Product Description: Dielectric loss measurement is a basic method in insulation test, degradation and partial defect of insulation of electrical equipment. It adopts high-power switching power supply, which outputs 45Hz and 55Hz pure sine wave and automatically increase the voltage to a maximum value 10 KV. It can filter 50Hz interference automatically, and it is applicable to the site test of substation and other places with large electromagnetic interference.
