Darui Electric recommends：
Dielectric Loss TesterIt is internally equipped with a high-voltage step-up transformer and adopts safety protection measures such as zero-crossing switching and lightning protection. During testing, it outputs high voltage at different levels from 0.5KV to 10KV,Simple and safe to operate. The 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 value and capacitance of various high-voltage power equipment. The instrument features an integrated structure with a built-in dielectric loss test bridge, variable frequency voltage regulation power supply, step-up transformer, and SF6 high-stability standard capacitor. The test high-voltage source is generated by the instrument's internal inverter and boosted by the transformer for testing the specimen. The frequency can be switched to 45Hz or 55Hz, 55Hz or 65Hz, using digital notch filtering technology to avoid interference from the power frequency electric field on testing.
