Product Detail

Product Tags

The PD detector is used for PD test of electric transformer, HV mutual inductor, arrester, HV switch, XLPE cables, etc. It is always used together with the AC voltage test system.


Digital PD detector

The PD test is main items of insulation test, and the PD value is main parameter of equipment quality. The detector is designed with modularization, the simulation adjustment part is designed as standard function module, and it can be changed according to users option. The module is Europe structure, which is convenient for maintenance. The detector adopts PC processing program and NI sampling module, the PD signal sampling and analyze is processed by digital filtering.
