Ultrasonic Partial Discharge Tester

Product Overview

Partial discharge phenomena in electrical equipment can have varying degrees of impact on both the equipment itself and the power grid, with severe cases even leading to equipment failure and grid collapse. Therefore, early detection of partial discharge in electrical equipment, accurate understanding of the equipment's operational status, and timely and effective elimination of potential faults are crucial for ensuring the safety of both the equipment and the grid. There are numerous methods for detecting partial discharge in electrical equipment, such as: pulse current method,DGAFrench and Ultrasonic Inspection MethodsRIVUltrasonic testing, optical measurement, radio frequency detection, and chemical methods are among the various detection techniques. Each has its strengths, but ultrasonic testing is particularly simple and convenient, making it ideal for routine equipment inspections and real-time monitoring of electrical equipment operation. Common electrical equipment partial discharge faults include corona, arc, and arcing. Corona and early arcing do not generate heat, and high environmental temperatures can mask these phenomena. They cannot be detected using standard infrared thermography, but they do produce ultrasonic signals, which can be detected remotely with an ultrasonic partial discharge scanner. Arcs and severe arcing generate both ultrasonic signals and high heat, so both infrared and ultrasonic methods can be used for testing. However, when partial discharge occurs internally within the equipment, infrared methods are ineffective. Ultrasonic partial discharge scanners can detect these issues on the surface or interfaces of electrical equipment.

The Ultrasonic Partial Discharge Inspector collects abnormal ultrasonic signals from power lines and analyzes them through software to diagnose potential faults in power line systems. This device can identify the location and type of faults without interrupting power supply. After the ultrasonic detector (ultrasonic sensor) captures the abnormal ultrasonic signals, they are transmitted to the main unit, where the built-in analysis software accurately diagnoses the type and severity of the potential faults, converting them into audible sound signals and waveforms for output. This aids inspection personnel in accurately detecting line faults and preventing severe accidents, thus avoiding unnecessary power outages and enhancing the reliability of power supply. Additionally, it improves the efficiency and reduces the labor intensity of the inspection personnel.
