The XHJS1000 inter-frequency dielectric loss tester is a high-precision test instrument for testing the dielectric loss tangent and capacitance of various high-voltage power equipment in power plants substations. The instrument is an integrated structure, built-in dielectric loss test bridge, variable frequency voltage regulator, step-up transformer and SF6 high stability standard capacitor. The test high voltage source is generated by the inverter inside the instrument and is used for testing the test object after being boosted by the transformer. The frequency can be changed to 50Hz, 47.5Hz\52.5Hz, 45Hz\55Hz, 60Hz, 57.5Hz\62.5Hz, 55Hz\65Hz. The digital notch technology is used to avoid the interference of the power frequency electric field to the test, which fundamentally solves the problem. The problem of accurate measurement under strong electric field interference. At the same time, it is suitable for the occasion of power supply detection after power failure. The instrument is equipped with an insulating oil cup and a temperature control device to test the dielectric loss of the insulating oil.
