WUHVModel UHV-2000A -Partial Discharge Detector

SHARE

The UHV-2000A multi-channel partial discharge detector is a 2-channel, desktop, TFT LCD display with reliable system and low failure rate. In addition to being used for partial discharge measurement of high-voltage electrical equipment (standard), it can also be used for online continuous monitoring of partial discharge of high-voltage electrical equipment such as large power transformers (optional). Truly achieving the integration of partial discharge measurement and online monitoring functions. This local discharge device is a specialized instrument for measuring and analyzing the insulation performance of power equipment. This system adopts modern electronic and computer integrated technology to achieve signal amplification (analog, electronic, digital), filtering, data acquisition, data processing, graphic display, and automatic generation of test reports, thereby completing partial discharge measurement and fault diagnosis. The scope of application, detection method, test circuit, technical performance parameters, etc. of this discharge meter fully comply with the requirements of the international standard IEC 60270-2000, the national standard GB/T 7354-2003 "Partial Discharge Measurement", and DL/T 417-2006 "Guidelines for On site Measurement of Partial Discharge in Power Equipment".
