Product Description

GDPD-414H New Design Handheld Partial Discharge Inspector

The GDPD-414H handheld Partial Discharge Detector 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. The portable high-efficiency partial discharge inspection tool for high-voltage insulation equipment. It can flexibly configure various sensors according to different products to be tested. TEV, ultrasonic and HFCT are suitable for partial discharge detection of high-voltage switchgear and ring network cabinet; ultrasonic and UHF are suitable for detecting the insulation state of GIS; ultrasonic 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.
