Portable Partial Discharge Tester PD inspection Detector

What is Partial Discharge(pd)?

In electrical engineering, partial discharge (PD) is a localized dielectric breakdown (DB) of a small portion of a solid or fluid electrical insulation (EI) system under high voltage(HV) stress, which does not bridge the space between two conductors. While a corona discharge (CD) is usually revealed by a relatively steady glow or brush discharge (BD) in air, partial discharges within solid insulation system are not visible.

HZ-9007 Portable partial discharger inspector Overview:

Portable partial discharge inspector is mainly used for live detection of high voltage electrical equipment. This product is simple to operate and adopts portable structure design which can inspect on line. It equips with specific sensors to detect various high-pressure devices, which can detect the insulation state changes inside the equipment timely. So the insulation failure could be dealt with in time.

HZ-9007 Portable partial discharger inspector Product Configuration:

 HZ-9007 Portable partial discharger inspector Application:

 Partial discharge measurement is applicable to cables and accessories with various insulation materials, such as polyethylene or paper-insulated lead-covered (PILC) cable. Partial discharge measurement is routinely carried out to assess the condition of the insulation system of rotating machines (motors and generators), transformers, and gas-insulated switchgear.
