Product Overview

The ETYJS-H insulation oil dielectric loss tester is a high-precision instrument used for measuring the dielectric loss angle and volume resistivity of liquid insulation media such as insulation oil.
Integrated structure, which includes main components such as dielectric loss oil cup, temperature controller, temperature sensor, dielectric loss testing bridge, AC test power supply, standard capacitor, high resistance meter, DC high voltage source, etc. The heating part adopts the most advanced high-frequency induction heating method currently available, which has the advantages of non-contact heating between the oil cup and the heating element, uniform heating, fast speed, and convenient control.
The AC test power supply adopts AC-DC-AC conversion method, effectively avoiding the influence of mains voltage and frequency fluctuations on the accuracy of dielectric loss testing. Even if the generator generates electricity, the insulation oil dielectric loss tester can operate correctly.
The internal standard capacitor is an SF6 gas filled three pole capacitor, whose dielectric loss and capacitance are not affected by environmental temperature, humidity, etc., ensuring consistent accuracy of the instrument after long-term use.
