High-Sensitivity Ultrasonic Partial Discharge Inspection Instrument
Introduction
With the continuous expansion of the power system scale and the increasing emphasis on the reliability of power equipment, partial discharge detection technology has become a key link in power equipment maintenance. Partial discharge not only leads to a decline in the insulation performance of power equipment but may also cause serious safety accidents. Therefore, it is particularly important to develop a high-sensitivity partial discharge inspection instrument capable of capturing weak ultrasonic signals.
