1DF6000 Variable Frequency Anti-Interference Dielectric Loss Tester is a high-precision testing instrument used in power plants, substations and other field or laboratory settings to measure the dielectric loss tangent (tan delta) and capacitance of various high-voltage power equipment. The instrument features an integrated structure, incorporating a dielectric loss test bridge, variable frequency voltage regulating power supply, step-up transformer, and SF6 high-stability standard capacitor. The high-voltage test source is generated by the internal inverter and boosted by the transformer for testing the test object. The frequency can be varied to 45Hz or 55Hz, 55Hz or 65Hz, using digital notch technology to avoid interference from power frequency electric fields, fundamentally solving the problem of accurate measurement under strong electric field interference. It is also suitable for testing with generator power supply after complete power outage. The instrument can be equipped with an insulating oil cup to test the dielectric loss of insulating oil.
