35kV High Voltage Portable Cable Fault Locator and Detector for Precise Underground Testing
The fault detector consists of a signal transmitter, a signal receiver, a probe, a plug and other parts. The transmitter and receiver are small in size, reasonable in structure, and beautiful in appearance. The instrument has the advantages of high sensitivity, strong anti-interference ability of the sound meter synchronization, convenient operation and carrying, and rapid and accurate location of fault points. The receiver and sound meter are synchronized, with high and low sensitivity settings. The transmitter is equipped with output indication and measurement KΩ function, which can replace the multimeter or megohmmeter to check the circuit's continuity, disconnection, and mixing, measure the size of the ground leakage resistance, and directly determine the nature of the fault. The transmitter adds an output terminal "Output 2", which broadens the detection methods and functions.
Technical performance
Transmitter
|
The transmitter panel is equipped with "power switch", "power indication"; "output selection", "high, medium, low"; "output indication" and "K measurement" switching switches, and the indicator light indicates the switching position; "output·KΩ measurement" shares an output terminal, which is switched by the "output·indication" and "KΩ measurement" switches; set "output 2" output terminal; square meter head indicates output and KΩ resistance. It can check the line on, off, mixed, and measure the size of the ground leakage resistance. |
