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 test the dielectric loss tangent and capacitance of various high-voltage power equipment. The instrument has an integrated structure, 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 internal inverter of the instrument and boosted by the transformer for testing the test object. The frequency can be changed to 45Hz or 55Hz, 55Hz or 65Hz, using digital notch technology to avoid interference from power frequency electric fields on the test, fundamentally solving the problem of accurate measurement under strong electric field interference. It is also suitable for occasions where power is supplied by a generator after a complete power outage. The instrument can be equipped with an insulating oil cup to test the dielectric loss of insulating oil. Usage conditions: -15℃∽40℃ RH＜80%
