n Non-intrusive Partial Discharge Detector

The non-intrusive partial discharge detector,as a convenient and simple method, is used for identifying the potential insulation faults which may cause power cutoff or personal injury.

The partial discharge emits energy in following manners:

Electromagnetic energy:radio wave, light and heat;

Sound energy: sound wave and ultrasonic wave;

Gas:ozone and nitric oxide.

The most practical non-intrusive detection technologies are all based on the detection of the high-frequency signals and the ultrasonic signals in the electromagnetic spectrum. The product is an instrument which has simple operation and is specially developed for detecting the activities of electromagnetic waves and ultrasonic waves.
