Professional Dielectric Loss Tester for Transformer Bushing Capacitor Insulation Performance Detection

XHJS1000R Dielectric Loss Tester applies digital notch technology to shield the test from power frequency electric field interference, which effectively addresses the challenge of precise measurement in strong electric field interference environments. The tester is compatible with generator power supply, and when matched with an oil cup and temperature control unit, it can conduct dielectric loss testing of insulating oil.
