1、 Product introduction

DYJS-8000 dielectric loss and capacitance tester is a high-precision testing instrument for testing dielectric loss tangent value and capacitance of various high-voltage power equipment in power plants, substations and other sites or laboratories. The instrument is an integrated structure with built-in dielectric loss test bridge, variable frequency voltage regulating power supply, step-up transformer and SF6 high stability standard capacitor. The test high-voltage source is generated by the inverter inside the instrument and used for the test of the tested object after being boosted by the transformer. The frequency can be changed to 50.0Hz, 47.5Hz  52.5Hz, 45.0Hz  55.0Hz, 60.0Hz, 57.5Hz  62.5Hz, 55.0Hz  65.0Hz. Digital notch technology is used to avoid the interference of power frequency electric field on the test, and fundamentally solve the problem of accurate measurement under strong electric field interference. At the same time, it is applicable to the occasion where the generator is used for power supply detection after all power outages. The instrument is equipped with insulating oil cup and temperature control device to test dielectric loss of insulating oil.
