The GDPD-414 Portable (GDPD-414H handheld) Partial Discharge Detector adopts smart quick intelligent power test system (Soft No. 1010215, trademark registration number 14684781 (14684481)). 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 GIS; Ultrasonic and HFCT are suitable for testing power 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.
Ultrasonic and TEV sensor (2-in-1)
●?Adopt high-speed?DSP/FPGA?sampling board, 4-channel synchronous data acquisition.
●?Software system: analysis software based on ARM embedded system
●?6/8/16 channels can be configured
●?8.1 inch tablet or Thinkpad notebook as optional
● 6/8/16 channels can be configured according to customer’s different demands.?
