Dielectric loss test is a effect way to detect the damp degeneration and local defect of electrical equipment insulation, it is used in transformer winding and bushing, current transformer, voltage transformer, breaker, high-tension switch, parallel capacitor, coupling capacitor and etc. Dielectric loss detector adopts frequency conversion power technology, and make use of single chip microcomputer and electronic technique to carry out automatic frequency conversion and data operation, to make the detector has the advantage of strong anti-interference, fast test speed, high accuracy, fully automatic digitization and simplification operation. Take the high power switch power supply to output 45Hz and 55Hz pure sine-wave, and automatic inflates, can supply 10KV voltage at most. Automatically filter 50Hz interference, it is suitable for site test of transformer substation.
