HSJS-IV frequency conversion anti-interference dielectric loss tester

1HSJS-IV frequency conversion anti-interference dielectric loss testerOverview

HSJS-IV frequency conversion anti-interferenceDielectric loss tester is a high-precision testing instrument used to measure the dielectric loss tangent and capacitance of various high-voltage power equipment in power plants, substations, and other fields or laboratories. The instrument is an integrated structure with a built-in dielectric loss testing bridge, a variable frequency voltage regulating power supply, a step-up transformer, and SF₆ High stability standard capacitor. The high-voltage source for testing is generated by the inverter inside the instrument and is used for testing the test sample after being stepped up by a transformer. The frequency can be changed to 50Hz, 47.5Hz52.5Hz, 45Hz55Hz, 60Hz, 57.5Hz62.5Hz, 55Hz65Hz, using digital notch technology to avoid the interference of power frequency electric fields on testing, fundamentally solving the problem of accurate measurement under strong electric field interference. It is also applicable to situations where a generator is used for power supply testing after a complete power outage. This instrument is equipped with an insulating oil cup and a temperature control device to test the dielectric loss of insulating oil.
