How to Use Network Cable Tester_ Application Method of Network Cable Tester
How to Use Network Cable Tester_ Application Method of Network Cable Tester
Now cables are used in all aspects of people's production and life, so mastering the operation method of network cable tester is the most basic requirement for cable users. So how to use network cable tester?Application method of computer network cable tester1. Insert the two ends of the network cable above the main and auxiliary survey lines respectively, and you can insert any head at will;2. Then turn on the switch of the line measuring instrument;3. Observe whether the indicator lights of 1-8 on the main and auxiliary line measuring instruments are on, and the order of lights is correct.4. For example, 1 light on the main survey line instrument should be on, and 1 light on the auxiliary survey line instrument should also be on. If the 1 light on the main line measuring instrument is on and the 2 light on the auxiliary line measuring instrument is on, it indicates that there is a problem with the network cable and it can not be used normally;5. Among the eight lights, as long as the lights 1, 2, 3 and 6 are on, the network cable can be used, because the data is transmitted through these four lines, and the other four lines are not used to transmit data.There are two standards for the order of network cables:1: The standard of t568-b is orange white, orange, green white, blue, blue white, green, brown white and brown.2: The standard of t568-a is green white, green, orange white, blue, blue white, orange, brown white and brown.The first standard is generally used.Second, insert the crystal heads at both ends of the network cable into the RJ45 port of the main tester and the remote test end respectively, and turn the switch to "on" (s is slow gear). At this time, the indicator heads of the main tester and the remote test end should flash one by one.Test of direct connection: when testing the direct connection, the indicator lights of the main tester should flash one by one from 1 to 8, and the indicator lights of the remote test end should also flash one by one from 1 to 8. If this is the case, it means that the connectivity of the through line is OK, otherwise it has to be redone.Test of interleaved lines: when testing interleaved lines, the indicator lights of the main tester should also flash one by one from 1 to 8, while the indicator lights at the remote test end should flash one by one in the order of 3, 6, 1, 4, 5, 2, 7 and 8. If so, the connectivity of interleaved lines is OK, otherwise it will have to be redone.If the line sequence at both ends of the network cable is incorrect, the indicator lights of the main tester still flash one by one from 1 to 8, but the indicator lights of the remote test end will flash one by one according to the order of the line numbers connected with the main test end. In other words, the remote test end cannot flash in the order of the above steps.Phenomenon of wire open circuit testWhen one to six wires are open circuit, the indicator lights of the corresponding wire number of the main tester and the remote test end are not on, and other lights can still flash one by one.When 7 or 8 wires are open circuit, the indicator lights at the main tester and remote test end are not on.Phenomenon of wire short circuit testWhen two wires are short circuited, the indicator lights of the main tester will still flash one by one in the order from 1 to 8, while the indicator lights corresponding to the two short circuits at the remote test end will be lit at the same time, and other indicator lights will still flash one by one in the normal order.When three or more wires are short circuited, the indicator lights of the main tester still flash one by one from 1 to 8, while the indicator lights corresponding to all short circuits at the remote test end are not on.
Wiring Methods of Cable Identification Instrument: Direct Method and Coupling Method
Wiring Methods of Cable Identification Instrument: Direct Method and Coupling Method
The wiring method of the instructions for use of the cable identifier is direct method and coupling method: the wiring method of the cable identifier is divided into two types: direct connection method and coupling method. The direct connection method is only applicable to the identification of uncharged cables, and the coupling method can accurately identify both live and uncharged cables. A) Direct connection method: the ground wire of the cable to be identified is disconnected, the signal current output line (red) is connected to any good phase, and the other end of the connected phase is grounded. The signal current return line (black) is grounded. Identification method: first judge the phase, subject to the initial swing of the meter pointer, and let the current flow along the direction indicated by the receiving clamp according to the direction shown in the figure. If it is a cable to be identified, the initial swing direction of the meter pointer should be to the right. In the process of phase judgment, if multiple cables are in the same phase, the amplitude can be compared. Adjust the sensitivity knob to the appropriate position to compare the amplitude. The cable with large amplitude is the cable to be identified. B) Coupling method: connect both ends of the cable to be identified with the earth (through core wire, shield or armor) to form a closed loop. When the direction of the output coupling clamp is consistent with that of the receiving coupling clamp, the cable with the positive deviation of the pointer direction of the meter is the cable to be identified. Identification method: under the condition that the output coupling clamp and the receiving coupling clamp are in the same direction, first judge the phase, subject to the initial swing of the meter pointer, and let the current flow along the direction indicated by the receiving clamp according to the direction shown in the figure. If it is a cable to be identified, the initial swing direction of the meter pointer should be to the right. During the phase judgment process of the cable identification instrument, if multiple cables are in the same phase, the amplitude can be compared. Adjust the sensitivity knob to the appropriate position to compare the amplitude. The cable to be identified has a large amplitude.
Correct Opening Method of Cable Fault Tester
Correct Opening Method of Cable Fault Tester
Why can't the fault point be found when using the cable fault tester? What is the correct opening method of cable fault tester? We need to understand some common problems of cable fault first, and then effectively solve the fault problems according to different problems. With the development of China's power system, the laying of high-voltage cables is becoming more and more common. Basically, the cables connected between distribution stations are very long. As long as the cables fail, it is very difficult to troubleshoot, and most of them are buried cables, which is difficult to judge. At this time, we need a cable fault tester to judge the correct fault point for us, So that we can quickly restore the power supply, we can analyze the problem according to several common cable faults. Cable faults are commonly divided into high resistance short circuit fault, phase to phase short circuit fault, low resistance fault, flashover fault and other common faults on site. 1. The low voltage pulse reflection method is applicable to low resistance (less than 10 times of wave impedance), grounding and open circuit faults, and can test the full length of the cable and the propagation speed of radio waves in the cable. In case of low resistance or grounding fault of the cable, the equivalent impedance at the cable fault point shall be the parallel connection of fault resistance and cable characteristic impedance. The smaller the cable fault resistance is, the more obvious the reflected waveform is. When the cable fault resistance is zero, it is total reflection. Because the equivalent impedance at the test end (input impedance of the test instrument) is greater than the characteristic impedance of the cable, the same polarity reflection pulse is generated at the test end. At the low resistance or ground fault, because the fault resistance is less than the cable characteristic impedance, the incident pulse generates the reverse polarity pulse after the fault point and transmits it to the test end. The falling edge of the received reverse polarity pulse corresponds to the reflected waveform of the cable fault point. In case of open circuit fault of cable, the equivalent impedance of cable fault is the series of fault resistance and cable characteristic impedance. Open circuit is equivalent to infinite fault resistance. In this case, the incident pulse will form total reflection, and the reflection pulse of the same polarity will be generated at the test end. The rising edge of the received pulse of the same polarity corresponds to the reflection waveform at the fault point. 2. First, use a certain voltage level The high voltage pulse with certain energy is applied to the faulty cable at the test end of the cable, causing breakdown and arcing at the high resistance fault point of the cable. At the same time, add the low-voltage pulse for measurement at the test end. When the measurement pulse reaches the high resistance fault point of the cable, it encounters an arc and reflects on the surface of the arc. When arcing, the high resistance fault becomes an instantaneous short-circuit fault, and the low-voltage measurement pulse will change obviously in impedance characteristics, so that the waveform of flashover measurement becomes a low-voltage pulse short-circuit waveform, making the waveform discrimination particularly simple and clear. This is what we call the "secondary pulse method". The received low-voltage pulse reflection waveform is equivalent to the waveform of a wire core completely short circuited to ground. Superimpose the low-voltage pulse waveform obtained when releasing the high-voltage pulse and when not releasing the high-voltage pulse. The two waveforms will have a divergence point, which is the reflected waveform point of the cable fault point. This method combines low-voltage pulse method with high-voltage flashover technology, which makes it easier for testers to judge the location of cable fault point. Compared with the traditional cable fault test method, the advantage of the secondary pulse method is to simplify the complex waveform in the impulse high-voltage flashover method into the low-voltage pulse short-circuit fault waveform, so the interpretation is very simple and the fault distance can be accurately calibrated. 3. The triple pulse method adopts the double impact method to prolong the arc burning time and stabilize the arc, which can easily locate the high resistance fault and flashover fault. The triple pulse method has advanced technology, simple operation, clear waveform and fast and accurate positioning. At present, it has become the mainstream positioning method of high resistance fault and flashover fault. The third pulse method is an upgrade of the second pulse method. The method is to first measure the reflected waveform of the low-voltage pulse without breaking through the fault point of the measured cable, then impact the fault point of the cable with the high-voltage pulse to generate an arc, trigger the medium voltage pulse when the arc voltage drops to a certain value to stabilize and prolong the arc time, and then send the low-voltage pulse, Thus, the reflected waveform of the fault point is obtained. After the superposition of the two waveforms, it can also be found that the divergence point is the corresponding position of the fault point. Because the medium voltage pulse is used to stabilize and prolong the arc time, it is easier to find the fault point waveform than the secondary pulse method. The cable fault tester often has to solve the following problems: 1. The diversity and complexity of cable faults determine that the cable fault tester needs complete functions and diverse test methods. 2. 2. To solve the fault, many instruments should be used together in order to achieve the result of solving the fault. 3. Different test methods are needed for cable insulation, fault location and different faults. 4. Sometimes the difficulty of cable fault test lies in the snow with a thickness of more than one meter and bad weather (the temperature is more than minus 20 degrees), which is also a test for underground cable detectors and testers to pass the above understanding. I believe you basically have some general and judgment on the cable fault problem and how to use the cable fault tester normally.
Classification of Underground Pipeline Detectors
Classification of Underground Pipeline Detectors
Classification of underground pipeline detectors 1. One category is to detect metal pipelines, electric / optical cables and some non-metallic pipelines with metal marker lines by using the principle of electromagnetic induction. This category is referred to as pipeline detectors for short. Advantages: fast detection speed, simple and intuitive, convenient operation and high sensitivity. Disadvantages: (underground pipeline detector) when detecting non-metallic pipelines, non-metallic probes must be used. This method is laborious and needs to invade the interior of the pipeline. 2. The other is to use electromagnetic wave to detect underground pipelines of all materials, which can also be used to find underground buried objects, commonly known as radar, also known as pipeline radar. Advantages: (underground pipeline detector) can detect pipelines of all materials. Disadvantages: high requirements for environment, poor sounding ability (it is difficult to check pipelines with deep buried depth), and high requirements for operator quality and experience. Any instrument is not superior and needs to be used together to give full play to their excellence. Traditionally, pipeline detectors only refer to pipeline detectors using the principle of electromagnetic induction. They are also instruments that use * many.

Tips to Clean Stainless Fiber Optical Tester
Tips to Clean Stainless Fiber Optical Tester
Dry plug cleaners (also known as click cartridges) can be cleaned by slight contamination. However, connectors can be charged during drying, and this method can attract additional impurities.Laboratory tests have shown the attraction of metal powders to optical connectors that are electrically charged after being wiped with the dry tissue of a typical fiberglass cleaner cassette style (Berdinskikh, Fisenko, Daniel, Bragg & Phillips, 2003 ). Dry wiping creates a static charge which can attract contaminants onto the plug after cleaning (IEC TR 62627-01, 2010, p. Similar contamination can also occur in the practice of front surfaces on non-cleaned surfaces that are cleaned during the dry cleaning process.The static charge of dry cleaning can be reduced by exposing cleaned connectors and the end face during the cleaning process to deionized air for 5-10 seconds. Dry cleaning, however, hardens the contamination and requires additional pressure from the operator, which can lead to surface scratches that can cause permanent damage to the end face.The only way you can guarantee that your connectors will do their job is to thoroughly inspect and clean them. Once the fiber optic connectors are cleaned, it is best to reconnect them and cover them with a cap to ensure that they are not dirty.Owners of fiber networks should explore their options for cleaning fiber connections and choose the method that best suits their business. It is essential to inspect and, if necessary, clean the fiber optic connections before mating.Choose from cleaners for many types of appliances such as SC, ST, FC, LC, and Mu (clinking cloths) designed for multiple applications. This one-put-cleaner is designed to clean male connectors, female bulkheads, adapters, fiber optic patches, cables and testing equipment. It also cleans the end faces of the ferrule to remove dust, oil and other impurities from scratches on the end faces.The F offers several types of slide-in cleaners including a push-in cleaner for LC and Mu (1.25 mm ferrule), a push-in cleaner for SC, ST, FC and LSH (2.5 mm ferrule) and a push-in cleaner for MTP and MPO connectors.The easiest way to clean your test port is to use Quick Clean (tm) Cleaner. A handheld connector removes dirt, dust, oil, grease and dirt from the front of the connector.The CKF Fiber Optic Cleaning Kit includes our TravelSafe Fiber Connector Cleaner (FCS3), Plug Cleaning Pen (MCC25), Lint-Free Wipe (LFW90) and Hand Connector Cleaner (FCC 7020) and Replacement Roll (FCC 7021). Many products use the procedures shown in the Fiber Cleaning Techniques tab. The following hints are helpful to pay attention when cleaning connectors.IPA alcohol can be used to clean fiber optic connectors, but is not the best solution to clean them. An optical cleaning fluid to clean the fiber optic connection is the better choice. It will help to clean the connectors without the risk of damage.Calculating a force of 2.2lbs per 200mm will bring you to 45,000 psi, so contaminated migration in dusty environments should not be a problem. You do not have to worry about dust residues contaminating migration, as there is no physical contact with the plug and it is cleaned during the mating process. The best way to avoid the risk of contaminated migration is to clean the uncovered plug and cable assembly with a wipe and then glue the cleaner to the plug that is in the adapter.Several fibers are installed in its own sheath to separate from the buffer tube, and these fibers are surrounded by a common sheath. Scattering light causes a change in the refractive index of the fiber used, and the Bragg grid distributes the Bragg reflector. Coherent fibers are bundles of fibres arranged in the same way at the end of the transmitted images and are used to protect the fiber optic cable from physical damage by mechanical insulation. See macro bends for a small radius around the fiber optic cable so that it can be bent without excessive attenuation or breakage. This type of fiber optic connector consists of two tapered, ferrule-shaped receptacles that work in both directions.Please contact me if you need additional photos or information about this high-end upgrade.

Look at your face and follow the golden rule of inspecting, cleaning and re-inspecting. After cleaning, do not forget to inspect the front face. It only takes one second for a network to have Fi-7000 FiberInspector Pro certified front face according to IEC 61300 3: 35 standard.A digital microscope is a normal hand-held microscope to which a camera is added. The usual magnification range is 100x to 800x, but the most popular magnifications are 400x and 200x for this task. The latter is a better choice because you can see more of the area being inspected.
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.
Instructions for Use of Underground Pipeline Detector
Instructions for Use of Underground Pipeline Detector
About the underground pipeline detector, Xiaobian has made a brief introduction to you in the previous article, so I won't repeat it one by one here. Today, we will mainly introduce the problems that should be paid attention to when using the underground pipeline detector. If you are interested in this, you can read this article carefully. Underground pipeline detector is a necessary tool for construction, acceptance and ground survey in municipal, electric power, telecommunications, tap water, gas, petrochemical, railway and other industries. Since its application in China, the underground pipeline detector for power production has a large number of users in the fields of power, telecommunications, water supply, heat, gas, petroleum, chemical industry, urban public utilities and so on with its excellent performance and flexible and convenient detection methods. The underground pipeline detector plays a positive role in improving the pipeline management level of relevant industries in China. The underground pipeline detector is composed of transmitter, receiver and accessories, which is used for accurate positioning, buried depth measurement and long-distance tracking of underground pipeline routing, as well as measurement and search of pipeline insulation fault points. The underground pipeline detector adopts multi coil electromagnetic technology, which improves the accuracy of pipeline positioning depth and the identification ability of target pipeline. It can also accurately track and locate the target pipeline in the area with dense and complex pipelines. The leakage current of the pipeline to the ground can be received by the two pins of the A-frame respectively, and the signal size displayed by the receiver is the difference between the received signals of the two pins. When the difference received by the two pins is zero, it indicates that the A-frame is directly above the fault point. Determine the wire path before fault location test. If there is abnormal signal loss during pipeline test, some signals may escape from the damaged insulation to the ground. When the path is determined and the general fault area is determined, cut off the connection point between the pipeline terminal and the ground to make the leakage current concentrate through the fault point. If the connection between the pipeline and the ground is disconnected, the current transmitted by the transmitter will flow out of the fault point, which will increase the escape of current at the fault point, which is conducive to fault location. Connect the transmitter to the cable, select the frequency as low frequency and the working mode as A-frame mode. Connect the receiver to the A-frame and insert the A-frame into the soil with appropriate force. Note: the underground pipeline detector receives the operation alarm of error current test. If a current reading of 000 is displayed during the current test, the receiver has detected an incorrect current reading. Check that the cable at the depth measuring point is straight at least 5m in front and behind. Check whether the signal within 10m is relatively stable, conduct depth measurement on both sides of the initial depth measurement point, and check whether there are adjacent interference pipes within 3-4m near the target cable. This is the most common cause of depth measurement error. Strong signals induced by adjacent pipelines may lead to 50% depth measurement error. For several depth measurements slightly deviated from the pipe position, the minimum depth reading is the most accurate, and the position indicated here is also the most accurate.

System software composition of cable fault tester: the cable fault tester is composed of test host, relative path signal generator, relative path signal receiver and detector. The cable fault tester includes integrated computer, bottom pressure single pulse generation and data processing methods to detect the spacing of common faults, and can also be used to accurately measure the length of cable and the rapid propagation of electromagnetic wave in cable. The relative path signal generator generates intermittent sinusoidal waveform data signals with a frequency of 30kHz and a force of 30V to find the relative path of the cable. The relative path signal receiver is used to receive the relative path data signal to search the cable route and estimate the depth of cable laying. The detector is used to accurately locate common fault points. Technical characteristics of cable fault tester: 1. Fault test system software: it can detect various common faults of various wires and cables, as well as the common faults of lead and short circuit faults of coaxial output power cables and local call cables. It can measure the propagation rate of electromagnetic waves in all known cable wires. The detection distance shall not be less than 16km 2. Relative path signal generator: output data signal frequency 30kHz, oscillation method, intermittent 3. Detector: detection sensitivity: 50 & omega; The video signal of the internal resistance outputs a 300Hz data signal, and the designated instrument inputs the data signal no more than 10&mu under the condition that the output remains 2V and the signal-to-noise ratio is better than 20:1; v. Input impedance: not less than 1.2k & omega;. Fault test method: the fault test is generally divided into the following processes: first find out the basic situation of common fault cable: measure the grounding resistance of common fault cable with megger and multimeter, and accurately measure the total length of cable with bottom voltage single pulse, whether there is disconnection, short circuit fault, etc. Second, according to the details of common faults, determine the appropriate detection methods and accurately measure the cable fault spacing. Generally, people set the common disconnection faults and resistance measurements at 100 & omega; The following cable faults are called low resistance (pilot) common faults, which are detected by bottom voltage single pulse method, and other common faults are detected by impulse flash method or direct flash method. Third, detect the relative path and depth of cable laying around common fault points. Identify the exact location of common fault points. Disconnect all connections between the cable head end and the terminal equipment head before testing. The control panel of the detection system software is equipped with two buttons for inputting amplitude and offset, which are respectively used to adjust the left and right parts of the input data signal strength and wave pattern for the next sampling.
