Introduction of Test Composition of Live Cable Fault Tester
Introduction of Test Composition of Live Cable Fault Tester
Cable fault tester is a commonly used cable fault detection equipment. This equipment is used with a variety of cable fault detection. Its stable performance and accurate detection make the cable fault detection more comprehensive. The work efficiency of inspectors has been greatly improved. Today we mainly explore the composition of live cable fault tester. Test composition of live cable fault tester: 1. Live cable fault tester is composed of the following parts: 1. Instrument host: cable fault flashover tester, referred to as flashover tester for short. Cable path test signal source, referred to as path tester. Cable fault point / path meter receiver, referred to as point meter. 2. High voltage accessories: high voltage pulse capacitor. The utility model relates to an AC / DC dual-purpose high-voltage test transformer. High voltage test transformer operation box. 2、 The test functions of the cable fault tester mainly include: 1. Purpose: it is suitable for low resistance fault test, short circuit fault test, open circuit fault test, high resistance leakage fault test and high resistance flashover fault test of various power cables with different sections and media, high frequency coaxial cables, municipal cables, street lamp cables, ground buried wires, etc. Specifically, there are the following types: (1) testable cables are equivalent according to voltage: low voltage cables and high voltage cables. (2) Testable cables can be divided into: power transmission cables; Control cable; Street lamp cable. (3) The testable cables can be divided into: directly buried cables, cables laid in cable trenches, overhead cables and more than two parallel directly buried low-voltage wires. (4) Testable cables can be divided into: short circuit fault; Phase failure; Low resistance fault; High resistance leakage fault; High resistance flashover fault is described in detail after fault classification. (5) If there is a cable identifier, we can find the cable we are looking for from multiple cables buried in the cable trench, that is, the cable identifier. (6) Both fault test and cable identification are conducted for power-off cables, and fault test cannot be conducted for live running cables. 3、 Introduction to the test principle of cable fault tester: 1. The host of this set of instrument is a host, which is mainly used for cable fault test. 2. It is a rough measuring instrument for cable fault distance, which can measure the approximate distance from the fault point to the cable test end face. 3. The lightning meter can measure the cable length and the propagation velocity of electromagnetic wave in the cable. The test principle of lightning meter is radar reflection method, also known as pulse reflection method. Single end test distance of lightning meter: 15km. Minimum test distance (blind area) of lightning meter: 15-20m. 4. Measurement error of cable fault tester: rough measurement error & plusmn; 1%, system (point) error & plusmn; 0.2m. In short, after accurately determining the fault point, dig a pit to find the fault point. 5. The principle of cable fault detector for finding cable path is to add electromagnetic wave signal to the tested cable and receive the signal of finding cable path through the pointing instrument. The minimum characteristic of receiving electromagnetic signal on the ground directly above the cable is used to determine the buried position of the cable.

Introduction to Relevant Knowledge of Power Cable Pathfinder
Introduction to Relevant Knowledge of Power Cable Pathfinder
Electricity has an incomparable position in our daily life. It can be said that without electricity, our life will be a mess. However, the power demand is so large that the cable will inevitably fail. In order to remove the fault in time, relevant detection equipment is essential. Today, Xiaobian will introduce you some relevant knowledge about power cable Pathfinder. In the power industry, due to the outgoing fault of power cable, it is necessary to determine the fault location. At this time, in order to accurately find the fault location and reduce the excavation quantities and search time, it is necessary to use the intelligent cable path detector to quickly and accurately determine the cable path. There are many communication cables and TV cables in the communication industry. When these cables have faults and need to be detected, their paths also need to be determined. In order to avoid damaging underground pipelines during excavation, reduce unnecessary economic losses and speed up the project progress, it is necessary to accurately know the location of buried pipelines. Due to the incomplete or missing data of underground pipelines in the past, the urban construction and planning department can not accurately grasp the distribution of pipelines under the city, resulting in many problems in the process of urban planning. In this case, the path of underground pipelines should be detected again and saved. Because the cable is directly buried or buried in the cable trench, it is difficult to observe the cable path direction when the GIS data is incomplete. Therefore, after pre positioning the cable, the next step is to use the Pathfinder to find the cable direction and find out the approximate location of the fault point, and the precise point at the back is meaningful. At present, the commonly used cable path detection method is audio induction method, that is, add audio current signal of specific frequency into the cable, the current signal generates magnetic field signal around the cable, sense the magnetic field signal with an induction coil, convert it into sound or waveform after filtering, and display it through earphone or display, Where there is sound or waveform display is where the cable passes, so as to detect the cable path. When using audio induction method to detect cable path, if you want to get a strong magnetic field signal on the earth surface, you must make some current pass through the earth, otherwise the magnetic field signal may be weak. The power cable Pathfinder is a device for detecting the underground cable path. It not only has the function of the old underground cable path detector, but also has some new functions, and has made a certain technical breakthrough. 1. Peak mode. In this mode, the relative position between the cable and the operator can be judged and the direction in which the operator should move can be indicated, Then find the buried location of underground cables. 2. Valley value mode, which has compass function, can judge the deflection direction between the operator and the cable, and prompt the operator to correct his direction in time until the position of the cable is found. 3. The automatic search and locking frequency function can search the signal frequency when the frequency input is unknown, so as to determine the access frequency and lock it. 4. Current and depth display can display the current and buried depth of underground cables in real time. 5. GPS positioning: when the location of the cable has been determined and the current geographic location information of the cable needs to be recorded, you can select the GPS positioning function to record the geographic location information of the current cable, and finally upload it to the computer for cable data management.
Data Cable Used at Home and in Business
Data Cable Used at Home and in Business
With the demands of modern life increasingly reliant upon technology it is vitally important to get the best equipment, as cheap as possible. Not only that but as consumers we should try and get as much value for our money by getting the most out of our equipment. Having the appropriate data cable is all part of this process and applies equally to large businesses and individual PC owners.There are various different types of data cable in use such as the Coaxial Cable, which is perhaps the most popular form of cabling as it is cheap and quite flexible. The Coaxial Cable is made of up a central copper wire surrounded by an insulator and a braided metal shield. The shield means it can be used over long distances at high speed, but the cable is usually only used for basic installations.Another type is a twisted-pair cable, which consists of two copper strands woven into a braid and covered with insulation. It is suitable for a local network with few nodes, a limited budget and simple connectivity. The drawback is that over long distances at high data rates it does not guarantee data integrity.Increasingly popular are fibre optic cables as they are lightweight, can accommodate a large bandwidth of up to several gigahertz and are immune to noise. These cables are very secure and allow connections over long distances. That said it is more expensive than Coaxial and twisted-pair cables and is therefore not ideal local network connections.Many of are using our PCs at home not just for working on spreadsheets and playing the occasional game of minesweeper, but also as part of our home entertainment system. When buying a new hard disk drive or HD DVD, Blu-ray, DVD or CD drive for your computer it is important to choose the most appropriate Serial ATA (SATA) data cable to connect the drive to the motherboard securely allowing for a direct path without bending the data cable too much. SATA is a single cable with a minimum of four wires creating a point-to-point connection between devices with transfer rates for SATA beginning at 150MBps.SATA data cables are much thinner than the old IDE cable drive and can be up to one metre in length. There are two speed levels too with SATA hitting up to 1.5 Gb/s and SATA II up to 3 Gb/s. In reality these types of speed are not reachable as it depends on the capacity of the computer.There are various different types of SATA available:• Straight Both Ends SATA Cable - This is the most commonly used as it has the same straight connectors at both ends and is the cheapest available. It is not ideal though if there is a large obstruction between the drive and the motherboard as it does not bend easily.• Straight Both Ends with Latches SATA Cable - This is the same as above but provides a more secure connection. The latch holds the data cable in place so it doesn't get easily pulled out.• Right Angled Drive Connector SATA Cable - This cable connector points downwards and is ideal for drives mounted higher up. However, it would be no good for drives near the bottom of a case or on the floor.• 270 Degree Drive Connector SATA Cable - Conversely this cable points upwards and therefore would suit drives near the bottom of a case and not those on top of a case or shelf.Data cables can be a real headache for businesses as their data centres try to keep up with modern technology and the growing traffic from the Internet, Smartphones and business applications. The numerous cables required to connect all the machines in data centres can cause huge costs to businesses as well as being an administrative nightmare. A typical computer server now requires at least eight or nine cables for tasks that should only need two connections and if you multiply that by the hundreds of servers in major data centres it can really get out of hand.Many companies are forced to buy extra equipment to manage all the necessary connections and coupled with the valuable office space this uses, it is costing a lot of money. In fact experts believe that as much as 15 percent of the cost of data equipment is spent on cabling. One of the solutions is to consolidate data cables if by moving to Ethernet, which has become the primary type of data cable linking almost all Internet-based networks, including the largest and most demanding telecommunications systems in the world.
Introduction to the Use of Cable Fault Finder
Introduction to the Use of Cable Fault Finder
Due to the cable fault caused by cable laying, the location of cable fault varies with the cable laying mode, and the location increases gradually. Among them, the laying side in bridges, tunnels and trenches is relatively simple, and the direct burial method is difficult to locate. When the nature of the fault is simple, a special cable fault finder is used, and it takes 4-5 days or even longer to locate the equipment within dozens of minutes. When using echo method to locate cable fault, sometimes by transferring fault phase and wiring mode, complex fault will often be transformed into simple fault to quickly determine fault location. It is of great significance for the power supply user department to win time for the emergency repair of on-site lines. Low voltage power cables are generally multi-core cables. When faults occur in continuous use after laying, they generally show two core and multi-core phase to phase or phase to ground short circuit faults. Sometimes when it is detected that the fault waveform collected by one core is not ideal, it can be considered to convert the wiring to other fault cores for fault waveform detection, which often has unexpected effects, The collected and detected waveforms will become more typical and regular, so the specific location of cable fault point can be determined quickly. During the long-term on-site measurement of cable customers, it is found that the fault of small section copper core directly buried power cable (35mm2 and below) and aluminum core cable may be accompanied by short circuit and wire breakage at the same time. During on-site detection, converting short-circuit fault into broken line fault measurement according to the different fault nature of each fault core will often double everything with half the effort. For the medium voltage direct buried power cable with extruded armor as the inner lining, the fault is mostly caused by external mechanical damage. When the insulation core fails, the inner lining may have been damaged. When the cable insulation fault is special and it is difficult to collect the waveform with a professional cable fault tester, the acoustic method can be considered, When the high voltage pulse is directly applied between the steel strip and copper shielding layer of the cable, it will often be fixed quickly. Using the cable fault finder in the field measurement process, we also found that when using the acoustic method to locate the fault of low-voltage cable. When the high-voltage line and ground wire are connected between the bad phase and the metal shield or armor, due to the low resistance metal connection state of the insulation resistance of the two, the sound is very small, so the probe can not be used to listen to the fixed point, and the effect is not ideal. Through the actual listening side on the site for many times, it is found that the distance between the discharge ball gaps is appropriately increased. At the same time, if the high voltage and grounding wire are connected between the two faulty phases, the discharge sound will become louder and the fault point will be determined quickly.
Why You Want a Cable Length Testers
Why You Want a Cable Length Testers
Today there are many different manufacturers and types of network cable testers on the market. Standard testers are used by those who want to check the quality of their cables. Bridge cables are a one-piece technology and are often used by certification testers as they can perform a greater variety of tests and there are short training videos on how to use them.Professional network testers are used in commercial environments and by certified professional cable installers at work. Professional testers have more skills when it comes to troubleshooting cables while maintaining a high level of accuracy. As an added bonus, professional testers allow you to track and archive your test results for future references.Some verification tools contain additional features such as a Time Domain Reflectometer (TDR) to determine the length of the cable and the distance between interruptions and short circuits. Some test tools do not provide information about bandwidth or suitability for high-speed data communication.There are many different types of network testers on the market today. LinkIQ cable network testers are easy to use, as explains Eric Webb, Fluke Network Product Manager in the video below. It shows how the settings can be used to perform a cable test with a network cable tester, save the results and upload them to link ware where they are available.To help you find the best network or cable tester for your use, I have compiled a list of test products that work well. The most obvious difference between a generic or standard tester and a professional tester is the brand cost, where professional network testers are more expensive than other testers.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.Selecting, selecting and purchasing a suitable network cable tester can be a complicated and challenging task. However, there are some essential factors that consumers should consider when purchasing a good network cable tester and absolutely should consider, as they can make or break the tester you are buying.For example, suppose you are looking for a good Ethernet cable tester or Ethernet cable speed tester. Network cable testers are sensitive products that are exposed to various extreme elements, suggesting that you should get a tester with a long warranty. In this case, you should look at the reviews of the Ethernet cable testers from previous buyers, who can confirm the star rating of the products.These three basic tests are performed in accordance with the EIA standards for twisted pair cables, wire mapping and cable length for high-speed performance. Check that the signal is strong and fast enough to meet network performance requirements. If you are testing the cable length with a calibrated capacitive tester it is better to test with a time domain reflector tester, as it can measure the distance to the location where the error is displayed.Make sure that the two ends of the cable you want to test are not connected to a TV, cable distributor, or any other related device. Find the right cable and touch the cable to one or the other so that a beep is generated. Connect one end of the coaxial cable tester to the wall plate on your coaxial cable wall and point the other end to the tester so that the entire cable can be assembled.This situation is indistinguishable from a real insulation break when the triggering current is exceeded. As the length of the cable increases, its capacity is limited by the rise time. The shorter the rise time, the higher the voltage, and the larger the DV / DT, the greater the amount of current required to charge the cable (parasitic capacity). Increasing the wire resistance of a longer cable helps to slow the charging current but requires a minimum dwell time of 10 s to ensure that the full cable length is reached before the test voltage is performed (leak measurements).Dirty contacts, bad bruising, cable damage and poor quality can provide strange and wonderful reading results. In order to reach the test voltage without damaging the traction current, it should be taken care to adjust the voltage ramp to the length of the cable so that it slows down. Cami Research ramp tester has a ramp which can be adjusted from 150 V / s to 5,000 V / s.The flagship cable tester VDV-II Pro uses a TDR to measure cable length and provide distance and error information. A TDR works by injecting a signal into the cable and measuring the time the signal reflects an impedance change caused by a short circuit.Standard testers are manual, while professional testers work automatically. Automatic testers allow you to apply contrasting IA- and ISO-testing methods and highlight many individual tests to verify conformity.The PocketHornet comes standard with a limited warranty of 1-2 years, depending on the region. Customers in the EU receive a 2-year warranty, while others only receive a 1-year warranty. It is not a cable certification device, but conducts cable qualification and verification.There are various types of cables on the market, but the most popular and widely used cable for modern technology is the coaxial cable. This article describes how to test a coaxial cable signal with a multimeter in situations where the transmitter does not work well. We may receive a small commission if you purchase a product through our selected links but the price of the product remains the same.In a house with a wired network connected to the TV, the cable coming from the family room should connect to a cable modem or router upstairs. There are 2 cables in the family rooms, the one marked "upstairs" is connected to the office upstairs and the other "downstairs" to the basement.

THIS adorable humanoid robot can be programmed to stab you when you're not looking.UBTech's home android Alpha 2 - which has proved a particular hit in the US - was hacked by security experts who used the experiment as way to expose how vulnerable the technology we are allowing into our homes is.In the clip, little Alpha 2 can be seen furiously stabbing a tomato with a screwdriver after researchers at security company IOActive managed to hack the software that controls it.They were also able to turn two other popular robot brands, NAO and Pepper, to capture video and audio as they manoeuvred around a home and send it to whoever they wanted.Factory robots could also be hacked, they warned.According to the boffins, a brand of industrial robots called Cobots that work alongside humans, are a potential hazard.They usually include certain safety and collision detection technologies to prevent possible injury from use of the products but an experiment has proven thatthese robots can be hacked remotely and used to injure humans around them."Even running at slow speeds, their force is more than sufficient to cause a skull fracture," IOActive wrote in a statement.Bride-to-be Regina Allen Elsea, 20, was recently crushed to death by a robot just two weeks before she was due to marry the love of her life.This research follows an open letter to the UN from tech leaders such as Elon Musk urging it to ban killer robots for warfare.But IOActivewarned that we also need to evaluate the security and dangers of robotic devices that are appearing in our homes and workplaces.Lucas Apa, IOActive principal security consultant, said: "The brightest minds in the word have spoken out this week about the potential dangers of robots, but I would argue that it isn't just the use of robots in the defence industry we need to worry about, it's also the ones in our homes and factories."I have no doubt that devices used by armed forces will be infinitely better secured than the devices weve tested but nothing is fool proof."Tech leaders already want killer robots banned for doing what theyre meant to do. Just imagine if they go rogue or do what malicious hackers tell them to do instead."We pay for your stories! Do you have a story for The Sun Online news team?
