Description
Overview
GAOTek partial transmission line tester is partial discharge is one of the common reasons for medium and high voltage equipment and cable insulation failures. partial discharge testing can detect harmful defects and help identify potential future failures. the 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 them into an audible sound signal and waveform, and finally diagnoses the type of hidden danger and grades by the analysis software. it helps inspection personnel to accurately discover the hidden troubles of the line faults prevent the occurrence of major accidents, and avoid unnecessary power outages.
