OEM Best pd calibrator Suppliers – GD-610C Remote Ultrasonic Partial Discharge Detector – HV Hipot
Partial discharge is one of the common reasons of medium and high voltage equipment and cable insulation failures. Partial discharge testing can detect harmful defects and help identify potential future failures. The GD-610C remote ultrasonic partial discharge detector uses an ultrasonic spectrum probe (sensor) to collect ultrasonic signals and analyze the signal to diagnose the charged detection, it is a diagnosis device for the accident of the distribution line. The device determines the line position and the fault type of the faulty hidden line when it is live. After collecting the ultrasonic abnormal signal, it transmits signals to the host, converts it into an audible sound signal and waveform, and finally diagnoses the type of the hidden danger and grade by the analysis software. ... -
