tan delta tester

The anti-interference pilot frequency dielectric loss tester is a high-precision instrument for testing the dielectric loss tangent and capacitance of various high-voltage power equipment in power plant, substation and other field or laboratory. The Capacitance Dielectric Loss & Dissipation Factor Tester is an integrated structure with 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 inverter inside the instrument, which is used to test the tested object after boosting by the transformer. The frequency can be 45Hz or 55Hz, 55Hz or 65Hz, 47.5 or 52.5Hz. The digital notch technology avoids the interference of power frequency electric field on the test, and fundamentally solves the problem of accurate measurement under the interference of strong electric field. At the same time, it is suitable for the situation of power supply detection by generator after all power failure.
