What Are the Fault Finding Methods for Rural Buried Cables
What Are the Fault Finding Methods for Rural Buried Cables
After a fault occurs in an underground cable, it is generally necessary to make a preliminary judgment on the nature of the fault. Then, according to the fault type, the appropriate fault location method is adopted to preliminarily locate the fault point; Finally, along the direction of the buried cable, carefully detect the fixed point before and after the position until the accurate position of the fault point is found, so as to realize the fault maintenance of the buried cable. Today, let's learn about the fault finding method of buried cables in rural areas. 1、 Analysis and judgment method before finding the fault of rural buried cable, it is generally necessary to understand the relevant situation of the fault, then conduct comprehensive analysis, find out the cause of the fault, and then find and eliminate it pertinently. For example, finding informed parties such as constructors, wire users and other relevant personnel to understand the situation in detail may often eliminate the fault in the shortest time at a small cost. The advantages of analysis and judgment are simple and easy, no complex instruments are required, and some faults can be eliminated in time. Therefore, it is difficult to eliminate it quickly by this method. For buried wires with a length of more than 100 meters, the fault can be found by human analysis and judgment without instruments. Sometimes, it takes more than a dozen times to excavate, and it is difficult to find the fault point in more than ten days. Sometimes, it will damage other wires in the same trench and cause new faults. This method is generally not used alone, but in combination with other instrument detection methods. The failure of buried wires is caused by the following reasons: 1. External force damage: it is the main cause of the failure. For example, repeated construction above buried lines, laying water pipes, building canals, planting trees, building buildings, etc. are often very easy to damage the buried wire insulation layer, resulting in wire breaking fault or grounding fault. 2. Joint failure: due to the nonstandard joint process during construction, it is very easy to cause mechanical damage at the joint. Or there are problems such as large contact resistance and poor insulation at the joint. After the wire runs under load for a period of time, the hidden danger at the joint often causes wire breakage or grounding fault 3. Nonstandard laying: there shall be strict process requirements when laying buried wires. However, due to the large workload, wide range and shortage of personnel in rural power network transformation, there are often some non-standard construction behaviors in some areas in the construction of buried lines. For example, when the trench is backfilled, the spinning soil is not used, and the soil block containing gravel is directly backfilled, which is very easy to damage the insulating layer. 2、 The simple ground fault tester is used to test faults. At present, many brands of ground fault testers on the market have similar working principles and test methods. Its working principle is: a fixed voltage signal is applied to the grounding wire, and an electric field is formed on the ground around the grounding point. The closer it is to the fault point, the greater the potential difference between the same distance, and vice versa. According to this principle, the ground fault point can be found. The market price of this kind of test instrument is hundreds to thousands of yuan. The buried wire fault with very small grounding resistance can achieve the test purpose. The fault finding method of rural buried cable is introduced here. I hope you can use it in your work.
Cable Fault Tester
Cable Fault Tester
Cable fault detector can be seen everywhere in our daily life. Cable fault detector plays a lot of roles. Cables on the road can divert people and vehicles. The guardrail beside the river can protect people from falling into the river. The guardrail beside the lawn can protect the lawn from being trampled by animals and people. Therefore, the role of guardrail is still great, The installation of guardrail is also very important. The installation of river guardrail needs special attention. Let's follow the traffic guardrail manufacturer to see how to install River guardrail. The river guardrail is a guardrail product installed next to the river to prevent pedestrians on the river road from falling into the river. The base to be fixed during the installation of the river guardrail can only be in the original position, which may cause the base to not be fixed and lose the significance of setting the river guardrail. Simply put, it is to install the guardrail at an oblique angle, hit 2 Road nails to fix the base, and the remaining 2 nail holes are used for later maintenance. After the base of the river guardrail is fixed, the column is installed. Insert the column into the base, and then install the expansion screw. After the screw is fixed, two people need to cooperate when tightening the screw. One person holds the column to keep it vertical. When tightening the screw, the other person can tighten the screws at both ends. In this way, the column and base are installed. The next step is to install the guardrail piece. The steel connecting sleeve connects the river guardrail and the column. This is generally fixed on the column before leaving the factory, so as to reduce the on-site operation process of constructors. Align the guardrail piece with the upper and lower connecting sleeves of the column, and connect the left and right accurately. The above is the introduction to the steps of installing the river guardrail. When installing the river guardrail, we should follow the steps strictly and master the installation skills of the river guardrail, so that we can make fewer mistakes in installation and ensure the performance of the river guardrail in the process of use. We are a professional guardrail manufacturer. If you need to buy our guardrail products, you can call us to communicate with us.
Experience and Depth Analysis of Cable Fault Locator
Experience and Depth Analysis of Cable Fault Locator
At present, the cable fault locator mainly adopts the method of acoustic measuring points for various main insulation faults of power cables with medium and high voltage and above voltage levels. Dgz-1827 cable fault locator has this function. Open circuit fault acoustic measurement method wiring diagram. For simple open circuit fault, if acoustic measurement method is adopted, wiring shall be carried out according to the following figure. For various short-circuit faults (so-called metallic grounding faults), it is difficult to judge the fixed point by acoustic measurement method. Audio method or other methods can be used. For sheath failure, the step voltage method is generally adopted for straight tunnel and the clamp current method is generally adopted for trench tunnel. For various faults of low-voltage cables (usually leakage and open circuit faults), acoustic measurement method, step-by-step method and audio method can be used. Fixed point method of fault point in special cases, discharge probe of fault point at the near end of fault cable. For the closed insulation fault, the suspicious part of the cable can be manually and mechanically moved, and the location of the fault point can be determined by monitoring whether the insulation resistance value of the fault phase changes. For the intermediate joint failure, compare the vibration sound waves of the faultless intermediate joint and the faulted intermediate joint to determine the intermediate joint failure (the vibration sound waves generated by the faultless intermediate joint are transmitted far away, there are no * big sound points, and the sound is relatively small). In recent years, due to the extensive use of various rubber and plastic cables, product quality and construction technology quality, it is difficult to locate cable faults. There are usually two cases of high ground wire loop resistance: 1. The copper shielding layer of the cable produced by the manufacturer is discontinuous and has a breakpoint. 2. When the cable construction unit makes the cable joint, the ground wire connection or lead contact at the cable joint is poor. From a technical point of view, improving the principle of fault fixed-point test will produce positive results. However, to fundamentally change the current situation of cable fault test technology, it is mainly an efficiency problem. We should start from two aspects of management and technology, and simply emphasize that on the one hand, it is not very objective.
How to Use Live Cable Identification Instrument to Identify Power Failure and Live Cable
How to Use Live Cable Identification Instrument to Identify Power Failure and Live Cable
Before we use the instrument.. Let's first understand the functions of the instrument panel buttons and what they are used for? Live cable identifier transmitter 1) signal output port: this port sends the signal to the cable to be tested through direct connection coupling. The instrument can automatically detect the connection mode (direct connection or coupling). When no output line is connected to this port, the screen mode menu displays "idle", and no signal is output at this time; 2) Frequency switching: the instrument has four output frequencies: low frequency, intermediate frequency, high frequency and radio frequency. It is suitable for different test systems and has strong anti-interference ability. When this button is pressed, the frequency will be switched between the above frequencies in turn; 3) Power regulation: the instrument adopts constant power output mode, and low, medium and high gears are optional. When this button is pressed, the power will be switched between the above gears. 4) Backlight switch: turn on the backlight for test after the instrument is turned on. When this button is pressed, the backlight will turn on. When it is pressed again, the backlight will turn off. 5) Power switch: the main switch of the whole instrument. When this button is pressed, the instrument enters the test interface; 6) Liquid crystal display: the instrument uses liquid crystal display for man-machine dialogue. 7) charging interface: it is used to charge the signal transmitter and the receiver of live cable identification instrument. 1) power switch: it is responsible for turning on and off the power supply. Press the state to turn on, and then press the key to turn it off; 2) Frequency switching: the instrument has four output frequencies: low frequency, intermediate frequency, high frequency and radio frequency. It is suitable for different test systems and has strong anti-interference ability. When this button is pressed, the frequency will be switched between the above frequencies in turn; 3) Backlight switch: turn on the backlight for test after the instrument is turned on. When this button is pressed, the backlight will turn on. When it is pressed again, the backlight will turn off. 4) Volume adjustment: adjust the sound volume of the speaker according to the demand, and adjust the volume in the order of small - medium - Large - off; 5) Gain adjustment: adjust the system gain according to the demand, the dynamic range is 000-100db, and the default is 60dB after startup; 6) Charging interface: it is used for charging the signal receiver. I believe you have a preliminary understanding of the instrument. Let's explain in detail how to use the live cable identification instrument: 1. Identification of power-off cable 1.1 direct connection conditions â—Ž it must be power-off cable; â—Ž know at least one end of the cable and separate the known end from the system, including disengaging the zero line and ground line; 1.2 signal application â—Ž in this method, the direct connection method is used to apply the signal (as shown in Figure 4); Turn off the power switch of the transmitter, insert the output connecting line into the output line interface of the transmitter, as shown in Figure 4, and connect the wire core with the red clip. Turn on the transmitter power switch and select the frequency: the transmitter has four or two frequencies: low frequency, intermediate frequency, high frequency and RF; After selecting the frequency, select the gear according to the actual situation. The transmitter is divided into high gear, medium gear and low gear. Generally, try to select a relatively low gear to save the power of the battery. After selecting the gear, the instrument automatically performs impedance matching. After matching, the transmitter displays the stable fault impedance of the current system, and the icon starts to rotate. 1.3 signal detection (identification) â—Ž connect the receiving coupling clamp to the receiver with a connecting wire with four core plugs at both ends; â—Ž turn on the power switch of the receiver to make its frequency correspond to the transmitter; â—Ž clamp the red line or cable head of the transmitter straight line with the receiving coupling clamp to reduce the gain so that the signal strength is about 800. Remember the current gain and strength value, and take this value as the reference value; â—Ž at the point to be tested, clamp the exposed cable with coupling pliers and find the cable with strong signal, that is, the cable to be found. 2. Identification of live cable 2.1 coupling conditions the cable must have known exposure points, and both ends of the cable must have grounding points or points associated with the ground (the live cable has been associated with the ground through the zero line); The coupling position shall be as far away from the end as possible; 2.2 one end of the four core aviation line equipped with the coupling signal application instrument is connected with the four core aviation base on the transmitting coupling clamp, and the other end is connected with the transmitter to complete the connection between the transmitting clamp and the transmitter; Put the transmitting coupling clamp on the cable exposure point, which is the signal application point. Note that the coupler should be completely closed; Turn on the power switch, select the frequency and match the impedance of the instrument; 2.3 signal detection (identification) â—Ž connect the receiver and receiver coupling clamp with four core aviation line; â—Ž at the transmitting point, clamp the receiving coupling clamp on the cable to reduce the gain so that the signal strength is about 800. Remember the current gain and strength value, and take this value as the reference value; â—Ž at the point to be measured, clamp the receiving coupling clamp on the exposed cable and find the cable with strong signal, that is, the cable to be found. If the cable is long, the signal will have a certain attenuation. At this time, compare the cable with strong signal.
Operation Precautions of Mine Cable Fault Tester
Operation Precautions of Mine Cable Fault Tester
Coal mines and oil wells are large users of cables. Due to the harsh underground operating environment, the annual damage of various cables is relatively large. In order to save expenses and reduce production costs, each mine and oil well is generally equipped with its own cable maintenance department. However, due to the limitation of testing equipment, the maintenance of cables is often unsatisfactory; The AC / DC cable detection device independently developed and produced takes the high-voltage breakdown method as the principle, so that users can accurately find the cable damage point in the maintenance process. Moreover, the mining cable fault tester also has the function of testing after the old cable is repaired. Therefore, this device is an essential maintenance equipment for cable maintenance companies in coal mines and oil wells. 1. Insulating rubber pad shall be added before the equipment. 2.

Operating Steps of Live Cable Identifier
Operating Steps of Live Cable Identifier
1. Connect the transmitting source: the live cable identifier inserts the red and black wiring plugs of the transmitting caliper a into the two red and black wiring posts corresponding to the transmitting source, and clamps the transmitting caliper a on the identified cable. The arrow on the transmitting caliper a points to the cable terminal. Both ends of the identified cable shall be reliably grounded. For cables that do not operate, the core wires at both ends can also be grounded. 2. Turn on the power switches of the transmitting source and receiver to check the direction: on the identified cable two meters away from the transmitting caliper, clamp the receiving caliper B to the cable, and the arrow on the caliper must point to the cable terminal. Then check the current direction and test connection direction. At this time, the pointer of the receiver ammeter must deflect to the right, and there is an audible and visual prompt at the same time. If the arrow of the receiving caliper B points to the transmitting source end, there will be no audible and visual prompt, and the pointer of the current meter will deflect to the left. Remember the deflection direction of the receiving caliper gauge. 3. Identification: at the identification point, use the receiving caliper B to identify each cable. During identification, the arrow on the receiving caliper must always point to the terminal direction of the cable, and the cable shall be clamped one by one. On the identified cable, the current meter pointer of the receiver must be deflected to the right, and the audible and visual alarm prompt shall be given at the same time. On other cables, the pointer of the receiver current meter must deflect to the left without audible and visual alarm. The pointer of the current meter of the receiver deflects to the right, and the audible and visual alarm prompt is the cable to be searched and identified. This test result is unique. That is, no matter how many cables there are in the cable trench, when each cable is identified with the receiving caliper B, only the receiver current meter pointer on one cable (the cable to be found and identified) deflects to the right and gives an audible and visual alarm. Dear customers: Hello, our company is a high-quality development group with strong technical force, providing users with high-quality products, complete solutions and superior technical services.

How to Repair Recessed Kitchen Lights
How to Repair Recessed Kitchen Lights
Recessed lighting in a kitchen is usually durable enough to provide many years of reliable light, but, it is not impervious to problems. Recessed lights tend to suffer from two common, yet unsightly, problems - light bulbs that continually blink on and off, and the eventual sagging light cover or trim. You can fix both of these problems quickly and easily. Turn off the circuit breaker that powers the lighting circuit and test the circuit with a non-contact voltage tester to ensure that the correct breaker is off before you work on the light fixture. Remove the trim or light cover from the recessed light by unhinging the springs that hold the trim or cover in place. Inspect the springs to determine if one or more of them are stretched out. If you notice they are, remove them and take them with you to your local hardware store to purchase the right sized replacements. Install the new springs on the trim or cover and re-install the trim or cover to the body of the fixture. Using needle-nose pliers to secure the springs to the inside of the fixture will make the job easier. Turn off the circuit breaker that powers the lighting circuit and test the circuit with a non-contact voltage tester to ensure that the correct breaker is off before you work on the fixture. Climb into the attic or crawlspace above the ceiling where you can access the top side of the recessed fixture. Locate the thermal protection device. This device can look differently depending on the fixture's manufacturer. Some thermal protectors are thin, black cylinders that are connected to the wiring junction box on the exterior of the fixture while others are small, silver discs that can be found on the top of the fixture. Open the wiring junction box on the fixture and find the two wires that are connected to the thermal protection device. Disconnect the two wires and remove the thermal protector. Take the thermal protector to the hardware store so you can purchase the properly-rated replacement. Install the replacement thermal protector and connect the two wires attached to it to the two wires that connected the original thermal device. Twist one wire on the thermal device to one of the wires and screw a wire connector over them, and then do the same thing with the second set of wires. You do not need to worry about wiring certain wires together with this device. Replace the junction box cover and restore power to the lighting circuit.
A Good Guide of Cable Continuity Testers How to Choose
A Good Guide of Cable Continuity Testers How to Choose
You are ready to start shopping now that you know a little more about what is involved in selecting a good voltage tester. Below are details of the best voltage testers on the market from trusted brands that manufacture high quality electrical tools. Trusted manufacturers in the power tool industry specialize in making electrical tools for professionals, and their products are top notch, with many professionals using gauges that they have purchased for decades.To help you find the best network cable tester for your use I have compiled a list of test products that work. I came across the Elegiant Network Cable Tester while working on establishing a LAN connection for a local company. With my extensive experience as an electrician, I can say that this is the best tool for testing cable connections.During the test, make sure you remove the cable from the computer, modem and router. Network cable testers are great for checking cable continuity and ensuring that the signal gets through. Klein Tools VDV501-823 and V DV Scout (r) Pro-2 test kits test voice (RJ11-12) and data (RJ45) via video-to-F connectors and coaxial connections.Platinum Tools TCB360K1 Cable Prowler (tm) Pro Test Kit - Full color cable length gauge with the ability to determine connection status, connectivity and POE detection. I love this type of cable tester because it provides accurate and accurate measurements of the integrity of cable connections. Make sure your cable and network connections are in top shape with this product.Network cable testers are sensitive products that are exposed to various extreme elements, so I suggest getting a tester with a longer warranty. A cable tester checks the electrical connection between signal and cable and confirms things like the wires at the end of the cable. With the HOSA CBT 500 you can test your cable gigging quickly and easily.Selecting, selecting and purchasing a suitable network cable tester can be a complicated and challenging task. In this article, a demanding effort is made to show you how you can test the continuity of circuits and how a good continuity tester will handle your situation. For example, suppose you are looking for a good Ethernet cable tester or an Ethernet cable speedometer.Continuity checks are indispensable for cable installation, cable marking, troubleshooting in the circuit and polarity testing. I have written this conclusion so that people can begin to make up their minds after reading this article. Here's a look at the best recommendations for the best continuity testers on the market.A continuity tester is an electrical test device that determines whether an electrical path has been established between two points where an electrical circuit can be produced [1]. The circuit is tested by activating and connecting the device. A voltage tester or plug analyzer detects the presence of electrical voltage.Voltage testers and socket analyzers indicate to which socket a device is connected. They are used for cables, wires, circuit breakers, lights, sockets and switches. A socket tester is the size of an electrical plug and works with any plug or socket.A fast, acoustic alarm test uses a digital multimeter to determine whether a circuit or line is complete or defective. A Fluke T6 1000 Pro electric tester with multimeter and field sensor not only detects the voltage, but also measures the voltage when disconnected from the outlet. During the sliding test of the fork wire, the tester reports the condition of the wire.The Fuke T6 1000 Pro electric tester also has other common settings that you would expect from a multimeter, including AC / DC resistance and Amperage measurements. One leads to the circuit breaker and fuse box, and the other conducts the current to other devices in the circuit. Using a multimeter, you can see whether the white or black cable is in the inverted socket and whether the earth cable inserted into the box is connected to the socket.When the receiver passes the correct circuit breaker, it emits a noise or light. To determine how hot the cable is, turn off the power, disconnect the socket and place a cap on the cable, usually one of the black ones. An electrician knows that with an electrical tester in his arsenal of tools, you never have to worry about getting a shock.It's the tester you want when you're constantly working with cables and circuits. If you work with coaxial cables, get a special tester, whether you are using a VDV512 or 007. Just like James Bond, they can spy on the cables and help you identify and label the right ones.
How to Choose High-quality  Ip Cctv Tester
How to Choose High-quality Ip Cctv Tester
If you are installing an analog surveillance camera system, you might want to consider taking a few handy cables with you. Later on this blog post, we will delve into the types of cables you will encounter when you start a hard-wired surveillance camera system. Let's start with Ethernet cables, the most common cables you need for your hard-wired surveillance camera system.For an analog HD / TVI surveillance camera system you need Siamese RG-59 cables. With these cables, you can power your surveillance camera and receive video information from the camera when only one cable is running. Use a Siamese replacement cable for your surveillance cameras, use it for your computer, use a Siamese replacement cable for your printer or use it when your network needs something different.By using PoE switches and injectors, IP cameras can supply and transmit video with a single cable, reducing cable costs compared to CCTV. CCTV uses coaxial cables, while IP cameras use the standard Cat 5E and Cat 6 network cables.IP cameras work by twisting a pair of coaxial cables for a wireless connection. One of the advantages of IP cameras is that they can be powered by a pair of twisted Ethernet cables, eliminating the need to lay electrical wires. IP cameras have an aVision capability of IP that surpasses analog systems.Analog cameras, for example, require a separate cable to control pan, tilt and zoom functions. They are also vulnerable to security breaches as the feed can be intercepted and the recording device stolen. IP cameras can accept power, video, audio and PTZ controls and control the signal via a single cable.The cabling you want to install depends on what you have in the surveillance camera system and what type of camera you want to choose. Mounting a surveillance camera on the outside of a house may seem like a daunting task, but it is the only way to get a camera to work the way it is designed. When viewing a PTZ camera, you want to monitor the live video feed over a large area and be able to zoom in and see more detail, especially in the case of a security guard overlooking a parking lot.There are two types of video surveillance systems: CCTV (closed circuit television, also known as analog) and IP (also known as network cameras ). IP cameras are digital cameras that send signals over a cable and are stored in a network. They are the biggest technological advance in cameras ever produced.CCV systems convert the video signal into a format that can be used for television (video recorders and DVRs). IP cameras convert video signals into IP packets which are transmitted to a storage device such as a server (NAS) or stored on board the camera over a data network (Internet network). High-quality HDCVI cameras (Solid Copper Coax Roll-off) can transmit video up to 1,600 ft.The recorded H.264 video file can't be played in Windows Media Player when it is played by the tester. The video stream is not displayed on the tester if the data rate is close to 0 KB / s. For this reason, the video file must be converted to MP4 format before it can be played in the test.Some private security cameras have optical zoom lenses (digital zoom) that trim and enlarge the camera while shooting. The more megapixels the camera sensor has, the more you can zoom in to see things better. The 1080p is the standard resolution of the cameras we tested and will benefit from a model with a higher resolution sensor.The warranty does not cover operating system errors caused by third-party apps. You can use the built-in Chrome or Firefox web browser to download the camera app and camera information. We recommend that you use an existing VLC to play the video clips.Our security camera testers are designed to facilitate the installation, maintenance and testing of security cameras. A shopper who bought a CCTV camera tester used it to test his camera before he started installing it in his home. A closed circuit TV tester is a handy tool for professional installers of CCTV security systems and do-it-yourselfers to set up and configure CCTV cameras from any source.CCTV testers feature a colour LCD screen, video port, rechargeable lithium batteries and several types of colour bars for signal output. The Cat6 cable is the most widely used cable in the world and Balun is widely used, but wearing analog video destroys clarity, so the passive Balun should be used according to the manufacturer's recommendations. For a fast and dirty workshop, check the analog camera and look at the test card to show clarity outside the camera.The Evertech screen is not the best, he writes, but it's fine given the cost. A reviewer looking for a CCTV tester IP camera and monitor kit is stating that it comes at an unbeatable price, considering he only needs it for a single home security setup.The Koolertron GH iPCT98, which is hard to beat even for $300, runs on Android and iOS apps, meaning that you can download and install a word processor or calculator program and reduces the number of devices a technician has to take to the field.The vast majority of private surveillance cameras now have mobile apps, and many are focused on how to do it remotely. Web portals offer more flexibility to access your videos and notifications. Another aspect of the functionality that should not be overlooked by a CCTV tester is the ability to work with analog IP cameras.Additional features vary from camera to camera, but our top picks offer enough variety to separate them from the rest of the competition. Remember that these cameras are designed to help you keep track of what is happening around your home.
