Shop Best Choose Good Cable Fault Tester in NOYAFA

In recent years, cables have been widely used in various industries. More and more equipment are used to detect cable faults, and their types and models are increasing. At present, there are a variety of instrument types and instrument names in the domestic cable fault detection instrument market. In addition to the common cable fault testers in China, they also appear in the market one after another. So, how to choose so many cable fault detection equipment? 1、 When you choose a cable fault tester, you need to know its own quality, such as whether its parts are compact and whether its whole shell is solid. These aspects can let you know what the cable fault tester you choose is, whether it has very solid quality and whether it has very strict production process, To determine whether it's worth your choice. But then again, the manufacturers still have a good guarantee for all aspects of the cable fault tester produced by themselves. Although the process is rigorous and other aspects are outstanding, it can indeed have a good test effect in testing the problems of the power system of the power grid. 2、 When choosing the cable fault tester, we should also understand its operation performance and simplicity, whether the performance is stable and whether it will be disturbed by electromagnetic field. These aspects also determine whether the cable fault tester we choose has very accurate test data, whether the operation is simple and whether it takes a long time.

As the running live cable is not allowed to damage any grounding wire and other connecting wires, nor is it allowed to directly add the output signal of the live cable identifier transmitter to the cable phase line with high voltage. Two difficult problems need to be solved for live cable identification. One is how to couple the cable identification signal to the cable; Second, the coupled signal is generally small, and the operating cable may have 50Hz power frequency electromagnetic interference composed of 50Hz unbalanced current, induced 50Hz interference current, cable distributed capacitance current, etc. the high-sensitivity receiving caliper has the problem of how to resist 50Hz power frequency interference. The charged cable identification instrument developed by US adopts single chip microcomputer coding and decoding technology and PSK technology widely used in the field of communication. The phase coded signal with an average value of 0 is transmitted on the transmitting caliper, and the single chip microcomputer in the receiving caliper performs phase identification after filtering the received signal by hardware and software. When the receiving caliper cards the cable according to the current direction, the identified cable ammeter deviates to the right, accompanied by audible and visual indication. The current direction of other cables is opposite to that of the identified cable, and the ammeter pointer deviates to the left. No audible and visual indication. This reflects the uniqueness of the identified target cable. It is easy to distinguish the identified cable from multiple cables. In addition, since the signal current strength on the identified cable is the same throughout the line, the electromagnetic signal strength received by the receiving caliper along the cable is the same. In principle, the identified cable is not limited by the length of the identified cable.

How does the cable identifier judge whether the cable is live? First: why should we judge that the cable is live: as an important instrument of power cable detection instrument, cable identification instrument has been used more and more widely. When there are multiple cables in the cable trench, it is necessary to identify a specific power-off cable, calibrate, move or cut off the cable, and other cables in the cable trench operate live, so the cable identification instrument shall be used for cable identification. Second: easy to use: compared with the cable fault tester, the use of the cable identification instrument is relatively simple. It is easier to use it by reading the instructions. Third: test example: since the cable shielding layer is usually connected to the ground, if other cables are also connected to the public ground in the cable bundle, the black output jack on the generator can be connected to the public ground, The return current is distributed in several cable shielding layers, and the return current is divided into many tributaries, which means that the difference current of the identified cable is large and the useful signal is clear. "Difference" means that the output current and its divided return current are in the same channel. As shown in Figure 4, there are 5 cables in Figure 4. Cable 4 needs to be identified. The "output current" of the cables to be identified is 20A. Assuming that the return current is evenly distributed among the shielding layers of all cables, there should be a return current of 4A in the cable to be measured. The difference in the cable to be identified is: 20A (output) - 4a (return) = 16A (difference). How to use the cable identification instrument I. working method of the cable identification instrument: the transmitter (host) is powered by 220V AC power supply, which is used for the power-off The cable to be identified, plus a fixed period, unipolar DC pulse signal. The output line of the transmitter is connected to the cable core and the grounding point or ground nail. The armor of the cable is disconnected from the earth, and the core is connected to the grounding point or ground nail at the far end. The loop can conduct pulse current, which can be read out by the meter on the receiver of the identifier. The current is determined by the loop resistance, and the loop resistance should be as small as possible. The wiring diagram of the identifier is shown in Figure 2. Note: during field use, if the grounding resistance is too small, the output current of the transmitter will also be large when the output adjustment knob is turned back to zero, and the protection circuit in the transmitter will act (shown as a small fast swing of the meter). At this time, the randomly configured 1 ohm 20W high-power resistor can be connected in series in the transmitter circuit. After the transmitter and receiver start working normally, the voltage induced in the sensor coil is displayed in the receiver header. The pointer swing direction of the header can display the current direction, that is, only the cable with current flowing out, the pointer deflects and swings greatly. This is the cable to be found. For all other cables, only the return current flows, the pointer deflects in the opposite direction and the swing is very small. The output adjustment knob on the receiver can adjust the signal strength. 2、 Wiring mode: 1. Before the test, cut off the tested cable, and the surrounding environment shall be in a safe state. 2. The generator is connected with the tested cable, and the red clip is connected with one or several cores of the identified cable. Connect the black clip to the ground nail. 3. Connect the core wire at the far end of the cable to the ground nail. 4. Disconnect the armor at both ends of the cable from the ground wire. 5. Plug the power cord into the power outlet. 3、 Identify the cable through the loop test. 1. In order to ensure the normal use of the instrument, pay attention to setting the test loop. 2. Connect the red output jack to the core of the cable to be identified, connect the black output jack to the ground, and connect the cable core to the ground at the far end. As shown in Figure 3, 3. The output current flows to the far end in the direction of the arrow in the cable, and all cores of the identified cable can be connected together through the earth return generator to obtain a clearer signal.

Small portable microscopes were once developed to test fiber optic cables. One of the best applications of such a device was the identification of trace fibres to determine the correct connection. This made it possible to find a specific fiber in a multifiber cable for proper connection and installation.Fiber optic is a fantastic medium for spreading light signals, but it needs to be amplified in contrast to copper cables. High-quality singlemode fibers have attenuation and a power loss of only 0.1 dB per kilometer. The signal power (measured in dB) is higher at the head of the network connection than at the end of the customer connection, and it is impossible to suffer light degradation over the length of the connection.When testing fiber optic cables for optical losses, the fiber tester must be connected to a test source that provides optical light on a standard launch cable calibrated to a 0 dB loss reference. For example, when the light source operates at a wavelength of 1310 nm, the optical power meter for testing should be set to 1310.A power meter at the other end of the circuit measures the test source for each fiber tested and quantifies the loss (dB) of each fiber during the test. For double-end loss tests, attach the cable to be tested to two reference cables connected to the source, one per meter. This allows you to measure the two connectors lost at one end for each power cable in the cable.If your electricity meter has an internal memory for data recording, make sure you know how to use it. Use your equipment in the office to test one of your reference tests (bridging cables in each direction) and use the end loss test to make sure it is good.Connect the optical source to Jumper 1, testing one end of the system fiber. Apply the adapter and insert the second jumper for the test, Jumper 2, which contains the same size fiber as the first, and an optical power meter. For the receiver, a separation cable is attached to the receiver socket to measure the performance of the meter.The power of the fiber optic cable or optical return loss is the light pulse that enters the end of the fiber optic core and the percentage of light reflecting back to the source. Optical fiber loss varies according to wavelength, so the optical power meter uses the same wavelength as the light source. The optical performance at the end of the fiber is the basis for the loss measurement, and the power source is presented to the receiver.Both singlemode and multimode fibers (VCSEL) are sensitive to optical return losses (ORL) expressed in decibels (dB). It affects the fiber and laser light source and reduces the data transmission speed.The OTDR test measures the backscattering of light to assess the quality of fiber optic cables. If the light at the other end is not visible, fractures or other problems may occur along the length of the fibre strand.The best way to test such impurities is to use a fiber optic or fiber optic microscope, a special microscope developed for inspection of fiber optics. Fiber optic communication systems operate in the electromagnetic spectrum in the infrared range which is invisible to the human eye.Fiber optic cables have become a more popular choice than Ethernet for network and telecommunications applications due to their high data transmission speeds over long distances. Fiber is the dominant medium for all types of mission-critical data center connections, backbone buildings, and remote campus networks. As the popularity of bandwidth-intensive applications increases, demand for fiber-optic installations and infrastructure is accelerating.Fibre optic cables play an essential role in the telecommunications industry. Testing fibre optic cables is considered one of the most confusing and misunderstood stages of installing a fibre optic system, but it is one of the last and most important procedures for installing a fibre optic network. For optimal savings in system performance, it is important to select a fiber optic cable that is matched to a spectroscopic analysis system.AFL Optical Fiber Identifier (OFIS) is a robust, easy-to-use test instrument that detects the presence of signals in optical fibers. The OFI is an important tool for field technicians to ensure live fibres are not separated and provides the ability to track the fiber from end to end.The optical time domain reflection (OTDR) is used as a fiber optic cable tester to test optical loss. The fiber optic cable is guided to one end through an OTDR to analyze the backscattering of light returning to the source using a high-power laser light that emits a predetermined pulse interval and is connected to the cable. This is the one-sided fiber test method used by fiber optic testers to analyze losses and pinpoint their location for installation, maintenance and troubleshooting.Fiber optic testing requires special tools and instruments to select the appropriate components and cables for the equipment to be tested. The most important test of insertion loss in an installed fiber optic cable system is carried out with a light source power meter (LSPM) and an optical loss tester (OLT), which is required by international standards to ensure that the cable is not lossless within the acceptance and installation budget.If it is a long installation cable with intermediate connections, you should verify each individual connection with an OTDR, as this is the only way to ensure which is the best. For this purpose, the loss testing method specified in OFSTP 1.4 is tested for losses in the installed cable system. Power Meter Optical Loss Test Set (OLT) Test Kit With the right equipment and adapter, the cable system you are testing (e.g.

Cable fault tester is a common cable fault detection equipment, and its accuracy and detection speed are guaranteed. We are used to evaluating this thing before we buy it, from its performance, value, price and other aspects. After that, we will decide whether to buy it. So, what evaluation should be done when purchasing a cable fault tester? When selecting the cable fault tester, the cable fault tester needs to understand its performance. Is its overall performance stable, or is it convenient in the whole operation? If there are problems in the operation and unstable performance of the cable fault tester you choose, it will certainly lead to more problems in the whole use, not to mention that the cable fault tester you choose is a test suitable for your own use, which can not highlight its whole use value. Therefore, when selecting the cable fault tester, we should pay attention to these two points: 1. How about the performance? Before choosing a cable fault tester, you'd better understand and test several different cable fault testers, that is, find some early tests to see if they really have high usability. 2. Quickly detect the fault point and find the problem of your own equipment in a very short time, If you can, it can show that it is a very good cable fault test. If you can't meet this standard, you will waste more time and money, and the selected cable fault tester will not be suitable for your own use. Therefore, we can understand how to select a more appropriate cable fault tester. After selecting an efficient and suitable cable fault tester, the next step is how to use it. What if you can better operate the cable fault tester to enable you to quickly detect the fault point? 1. Understand the instructions of the cable fault tester. After you get a cable fault tester, you need to understand its operating instructions before preparing for operation. Some people feel that they have a certain understanding of the cable, so it is not necessary to understand its operating instructions when using it. In fact, this is not the case, Most of the time, my knowledge is very different from professional operation, so I can understand the contents of the operation manual in advance before use, which naturally has a very good guarantee for the whole operation after use. 2. Check the circuit. When using the cable fault tester, do you need to test in advance or find out if there is a problem with its circuit connection? If there is a problem that needs troubleshooting, you also need to know whether the whole connection is normal in advance, so as to have higher detection efficiency in the whole detection, know the problem of cable fault, and find a good solution, so as to ensure the working performance of the whole power system. Generally speaking, after the carefully selected cable fault tester, the equipment performance of the cable fault tester is guaranteed. In the process of cable fault detection, the corresponding fault results can be obtained according to the fault performance in the operation manual.

Buried lines have been widely used in recent years. Therefore, many rural electricians and maintenance personnel are not familiar with the method of buried cable fault tester. If there is a fault in the buried line, without advanced instruments and better test methods, the fault can not be eliminated within the time limit of the service commitment of the power supply enterprise, which not only wastes time and manpower, but also affects the image of the rural power supply enterprise and frustrates the farmers' enthusiasm for the transformation of the rural power network. Therefore, it is urgent to be more professional in rural land buried line. Buried cable fault detector is a more effective fault detection instrument. Compared with buried cables, buried power cables have been used for decades in China. Buried cable fault tester has developed from resistance bridge, capacitance bridge test and standing wave test to flashover test. The development of the instrument has experienced the flash meter with ordinary oscilloscope tube display and the flash meter with storage oscilloscope tube display. Up to now, the intelligent instrument has been developed and produced. The buried cable fault tester adopts new technologies and processes such as large-scale integrated circuit, computer processing technology, large screen liquid crystal display technology and so on. After improving the power cable testing instrument, the buried wire fault is tested, and its effect is very good and efficiency is high. After a lot of practice, a buried line fault is generally tested. The buried cable fault tester is within 30 minutes from the beginning to the end, and the accuracy is very high.
