4 Channel Transformer Switchgear Live Line Partial Discharge Detector


GDPD-414 adopts smart quick intelligent power test system (Soft No. 1010215, trademark registration number 14684481). HVHIPOT company introduces international advanced PD detection technology to develop and produce portable and efficient PD inspection tools for live high-voltage insulation equipment. It can flexibly configure various sensors according to different tested objects. TEV, AE and HFCT are suitable for partial discharge detection of high-voltage switchgear and ring network cabinet; AE and UHF are suitable for detecting the insulation state of GIS; AE and HFCT are suitable for testing the insulation state of the cable. The built-in expert diagnosis system can analyze the test data and judge the discharge energy and possible parts. It is widely used in electric power and railway.
