Portable Hand Held Pd Detector Partial Discharge Tester
The instrument adopts a portable design, which can scan and detect directly on the switch cabinet shell without any influence or damage to the operation of the switch cabinet. At the same time, the measured signal can be stored and replayed on the TF card for easy reference, and the supplied earphones can be used to hear sound of electric discharge.
Application for Partial Discharge Testing Set
Partial discharge usually occurs where the wire insulation is damaged. It can cause short circuits and fires, resulting in destructive fatal failures. The most dangerous situation is the poor isolation of the external as a whole, and the gradual collapse leads to unexpected equipment failures. Therefore, continuous or regular monitoring of high-voltage equipment and timely detection of partial discharge are very important.
Partial discharge detectors are widely used in the measurement of partial discharge of various high-voltage electrical products such as transformers, transformers, high-voltage switches, zinc oxide arresters, power cables, etc., product type tests, insulation operation supervision, etc.
