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.
What Are the Test Steps for Cable Failure
What Are the Test Steps for Cable Failure
The detection of cable fault generally goes through four steps: diagnosis, ranging, path finding and fixed point. 1. Diagnose the nature of cable fault, that is, determine the type and severity of fault, so that testers can suit the remedy to the case and select appropriate cable fault location and fixed-point methods. Measure the fault resistance with a megger and multimeter to determine whether the cable fault is high resistance or low resistance; Flashover or closed fault; Whether it is grounding, short circuit, disconnection, or a mixture of them; Is it single-phase, two-phase or three-phase fault. 2. Ranging cable fault location, also known as rough measurement, uses instruments to determine the fault distance at one end of the cable. The common fault location methods on the site include classical bridge method and modern traveling wave method. Use jcd-971 cable fault locator or cd-71 cable fault locator. 3. Use pd2000 cable path identifier or cd-12 / 22 cable path identifier produced by Zibo Electric Co., Ltd. for path finding. 4. Fault location acoustic magnetic synchronization method: use cd-81 cable fault locator to synchronize with the discharged electromagnetic signal and digitally sample the sound signal, The sound waveform at the moment of discharge is displayed on the LCD screen. The waveform can be maintained continuously for the operator to distinguish carefully, avoiding the disadvantage of transient sound. Moreover, the actual discharge waveform is obviously different from the surrounding noise. More importantly, the sound waveforms of multiple discharges are very similar. When the sound waveforms of multiple discharges are observed to be the same, It can be clearly judged that the discharge sound has been collected. Because the response range of acoustic measurement method is generally very small, when the discharge sound is heard, it is very close to the fault point, generally not more than 5m, or even within 1-2m
Application Field of Cable Fault Locator
Application Field of Cable Fault Locator
The application field of cable fault locator is in the power industry and some industries using cables, especially in some complex power systems, it is very difficult to find the fault of underground cable lines. However, in this regard, the continuous emergence of equipment with various functions and simple operation can not only reduce the high cost of fault detection, but also reduce the inevitable long-time power failure when difficult to find (cable fault locator) cable fault, which brings a lot of convenience to troubleshooting. Direct buried cable fault detection in underground direct buried cable and underground residential power distribution (URD) system is a very time-consuming thing, and will cause very inconvenient power failure to users. Some technologies may also damage the cable. For some equipment with high technical requirements, its operation is more complex, and only operators with strict training can use it, which brings a lot of inconvenience to the popularization and application of this kind of technical equipment. Therefore, the selection of appropriate technology depends partly on the knowledge of cable system design understood by the designer of fault detector, and also partly on the professional and technical knowledge of equipment and operators in this regard. With appropriate equipment and professional technology working on site, it is the first step to detect faults quickly and effectively. Hammering (pulse) method many power companies use hammering (pulse) method. This technique is effective in detecting high resistance faults in a simple (cable fault locator) cable system. The hammering method includes using a pulse or impulse voltage to impact the power cut cable. When an effective high voltage pulse strikes the fault area, the fault point flashover and produces a hammering sound that can be heard by the operator along the cable surface. However, detecting cable faults often requires several hammers, and repeated shocks may damage the cable.
