There are two important steps in where the cable fault occurs Two important steps in the cable fault detection Manufacturer Friends who are familiar with cable faults know that finding the location of the cable fault does not have to be like looking for a needle in a haystack, there are many locating methods , coupled with new detection technology instrumentation make this task easier and time consuming, however, you should understand that no“optimal”a single method or combination of methods. Your choice of the appropriate method for your situation, and the techniques for using that method, are the keys to safely and efficiently locating cable faults without damaging them. Pathfinding Cable Fault Detection Manufacturer's pathfinding is used when the specific direction (routing) of the cable is unknown. If you know the site very well, you can skip this step. The specific method is: ① Connect the red wire of the generator to the faulty phase of the low-voltage cable, The black wire of the transmitter is connected to the ground ② The receiver is connected to the magnetic rod with a special wire, and the magnetic rod is perpendicular to the ground. ③ Turn on the power of the receiver and transmitter, and press the path selection button on the transmitter setting panel. The transmitter has a short-term signal matching process. This process does not require manual intervention. The time is about 2S minutes. Therefore, during the pairing process, do not place the transmitter and the receiver too far apart. Otherwise, if the matching is unsuccessful, the measurement will be inaccurate. ④ After the pairing is completed, the transmitter does not move, the receiver measures along the road, and the receiver sends a signal when it receives a signal.‘Didi’There is a prompt sound with a gap. If the sound gradually weakens or even no sound indicates that the receiver is just above the low-voltage cable vertically, it can be marked before the end of the search.
After the fault location path is found, it is necessary to locate the fault. Under the condition that the wiring remains unchanged, set the panel of the host where the fault occurs to the fault option, and connect to the unit module of the step potential collector, parallel to the path of the low-voltage cable. Search, observe the direction indicated by the arrow during the search process. If it is on the red side, the step sampler will move to the corresponding side, and so on. When it moves to the red (green) side, the indicator will indicate the opposite direction. Below is the low-voltage cable fault point.
