In Depth Understanding of Live Cable Identifier
In Depth Understanding of Live Cable Identifier
Everyone should be familiar with the live cable identifier. Xiaobian introduced it in the previous article. It is a very common cable construction and maintenance equipment. At present, there are both instruments for identifying non operating cables and instruments for identifying operating cables. Now we will introduce some knowledge about live cable recognizer. 1、 The transmitter panel of live cable identification instrument is introduced as follows: 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: the instrument has a backlight controllable function. The backlight can be turned off during the day to save power. At night, the backlight can be turned on for test. When this button is pressed, the backlight will be turned on. When it is pressed again, the backlight will be turned 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 of cable identification instrument: the instrument adopts liquid crystal display for man-machine dialogue. 2、 Precautions for the use of live cable identifier 1. If the operating cable has voltage and there is no load, there is no current flowing on the cable. At this time, the magnetic field cannot be detected. It is considered to be an uncharged cable, which is very easy to misjudge. 2. If the cable is not running, but if this cable is parallel to other running cables, there will be induced current and magnetic field. At this time, the instrument will also have indication, and misjudgment will occur. 3. If there are multiple cables in the cable trench, these multiple cables will generate a magnetic field. At this time, there will be a magnetic field generated by 50Hz current in the whole area. At this time, there will be a magnetic field in the whole area, which makes the discrimination impossible. It is easy to misjudge. 3、 Basic parameters of live cable recognizer insert 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 clamp the transmitting caliper a on the identified cable. The arrow on the transmitting caliper a points to the cable terminal. 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 the identification point, identify each cable with receiving caliper B. 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.
How to Choose Fiber Optical Tester
How to Choose Fiber Optical Tester
Transmitter and receiver jack are fiber optic connectors that measure the power of the transmitter by connecting the test cable to the source and measuring power at the other end. The receiver is the one who disconnects the cable attached to the receiver jacks and measures the output with one meter.Other methods of testing fibre optic connections include starting the cable from the receiving cable and connecting it to an electricity meter. The standard loss test is an installed cable system that includes loss measurement to test the cable connection at each end. If you can, you can measure the loss from a connector connected to a reference cable, a loss fiber connection, or any other connector on the cable you want to test.This allows you to measure the two lost connectors at one end and the loss from cable to cable. The source counter duplicates the transmitter and receiver of the fiber-optic transmission connection, so that the measurements correlate with the actual system loss. The optical return loss (ORL) is expressed in decibels (dB) and affects how the light source or fiber reduces the data transmission speed.The optical time domain reflectionometer (OTDR) is used as a fiber optic cable tester to test optical losses. Using a high intensity laser light that emits a predefined pulse interval and is connected to the cable at one end, the cable is guided through an OTDR to analyze the backscattering of the light returning to the source location. A simple instrument that injects visible light is called a fiber tracer or visual fault locating mechanism.Calibrated optical light sources (OLs) can be used with an optical power meter (OPM) in conjunction with an OPM to quantify the insertion loss of the members during powering on. An important test of loss of input in an installed fiber optic cable system is performed with a light source power meter (LSPM), while an optical loss test kit (OLT) is required as an international standard to ensure that the system has a loss budget for acceptance and installation. The OLT, which uses both optical light sources and power meters, is considered the best fiber test practice to ensure the optical power budget and design specifications.Two devices are required to test the end-to-end performance of a fiber optic system: an OPM test and a light source. The testing of optical fibres requires special tools and instruments to select the appropriate components for the cable system to be tested. The source of the power meter, the optical loss test kit (OLT) and the appropriate device adapter are the cables and equipment you will test.Outside the fiber system, cables with an OTDR are tested for end-to-end losses to ensure that the installation is carried out correctly. The OTDR can also be used for troubleshooting, e.g. Interruptions in places due to excavations. Installers are often asked to use a loss test set up with a source current meter and OtDR to perform bidirectional tests, provide accurate cable documentation and certify their work.This video gives you a clear test procedure for fiber power meters and shows you how to test fiber adoption losses with two fiber optic test devices. Testing light sources of power meters is also known as the One-Jumper method as the most accurate way to measure the end-to-end signal loss in the fiber known as attenuation. If the light source operates at a wavelength of 1310 nm, for example, the optical power meter is set to 1310 for testing.The OLT Optical Loss Test Kit is a mainstay in the testing of fiber optic cables as it provides a precise method for the total loss of a connection as required by industry standards to ensure that the connection meets the loss requirements of a particular application. When fiber optic cables are in the facility, you need to test for continuity and end-to-end losses to resolve problems. Regardless of whether it is a long installation cable or an intermediate cable, you want to verify every single connection with an OTDR, because this is the only way to ensure that each one is good.Knowing how to select, install and maintain fiber optic cables is important to optimize system results. Combines fiber spectroscopic analysis systems to achieve optimal performance and results. Inline and flexible fiber-optic process analyzers and systems enable the user to place measuring probes at several points on one instrument, thereby reducing costs.Patented fiber constructions with emphasis on high-quality materials and spectroscopically guided waves are designed for high transmission efficiency and durability. The significant increase in the number of applications supporting data centres has resulted in more cable connections being established than ever before, and available space is a priority. Fusion splicing is used for FTTH applications to install connectors. Drop cable customers can use the new splice connector technology for fall cable fusion splicers.For example, expensive 10G certified Cat6A cables can be used instead of duplex fiber-optic cables, which require expensive transceivers. As a result, high-density solutions such as MTP / MPO connectors and multi-fiber cables, which require less wire space than single duplex cables, are becoming increasingly popular. While some manufacturers offer locally installed MTP and MPO connectors, many data center managers opt for Multi-Fiber Trunk Cable (MTP) or MPO (Factory Terminated End Fusion Splicing) or pre-terminated MTP (MPO) or Multi- Fiber LC Pigtails.They combine a fiber optic cable with a transceiver and eliminate the connectors. Fiber optic cables, also known as fiber optic cables, transmit data in light pulses through flexible pure fibers, glass or plastics. Thanks to their high data transmission speeds over long distances, they have become a popular choice for Ethernet networks and telecommunications applications.With thousands of connections, excessive slack leads to a lot of congestion, which restricts the proper airflow and cooling. An alternative is the purchase of multi-fiber pigtails that can be spliced into a multi-fiber cable. Sharp bends of 1.5 cm radius should be avoided, as they strain the fiber and cause optical losses.

Working Principle of Cable Fault Tester
Working Principle of Cable Fault Tester
Working principle of power cable fault tester consists of three main parts: power cable fault tester host, cable fault locator and cable path tester. The host of the cable fault tester is used to measure the nature and total length of the cable fault and the approximate position between the cable fault point and the test end. The cable fault locator determines the exact location of the cable fault point based on the approximate location of the cable fault point determined by the host of the cable fault tester. For buried cables with unknown direction, a pathfinder shall be used to determine the underground direction of the cable. The basic method of power cable fault test is to apply high-voltage pulse to the fault power cable to produce breakdown at the cable fault point. When the cable fault breakdown point discharges, it generates electromagnetic wave and sound at the same time. The working principle of the application of arc reflection method (secondary pulse method) in cable fault location: firstly, a high voltage pulse with a certain voltage level and energy is applied to the faulty cable at the test end of the cable to make the high resistance fault point of the cable break down and burn arc. 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 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 fault point. Compared with the traditional test methods, the advantage of the secondary pulse method is to simplify the complex waveform in the impulse high-voltage flashover method into the simplest low-voltage pulse short-circuit fault waveform, so the interpretation is very simple and the fault distance can be accurately calibrated. 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 obtain the fault point waveform than the secondary pulse method. Compared with the secondary pulse method, the triple pulse method does not need to select the synchronization time of arc burning, and the operation is also more simple.
