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 anti-interference dielectric loss tester instrument 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, 55Hz, 55Hz, 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, Capacitance&Dissipation Factor Test Set is suitable for the situation of power supply detection by generator after all power failure.

4. Multiple test modes
The capacitance and tan delta test kit can be tested by direct connection method, reverse connection method, CVT self-excitation method, etc.
5. Measure CVT without removing high voltage lead
The transformer dielectric loss tester can correctly measure the dielectric loss and capacitance of CVT without removing the high voltage lead of CV.
6. CVT reverse shielding method for measuring C0
The anti-interference dielectric loss test instrument can measure the dielectric loss and capacitance of C0 at the upper end of CVT by reverse shielding method.
7. High speed sampling signal
The inverter and sampling circuit inside the instrument are all digitally controlled, and the output voltage is continuously adjustable.
8. Multiple protection, safe and reliable
The anti-interference dielectric loss tester has multiple protection measures such as input voltage fluctuation, output short circuit, over-voltage, over-current and temperature to ensure the safety and reliability of the instrument. The instrument also has grounding detection function to ensure that ungrounded equipment is not allowed to boost voltage.
