1、 Product Overview:
The insulation oil dielectric loss tester is an integrated high-precision instrument used for testing the dielectric loss angle and volume resistivity of liquid insulation media such as insulation oil. Internally integrated with 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 to effectively avoid the influence of mains voltage and frequency fluctuations on the accuracy of dielectric loss testing. Even if the generator generates electricity, the instrument can operate correctly. The internal standard capacitor is SF6 gas filled three pole capacitor. The dielectric loss and capacitance of this capacitor are not affected by environmental temperature, humidity, etc., ensuring consistent accuracy of the instrument after long-term use.
Insulation oil dielectric loss testerInternally, all digital technology is used for intelligent automation measurement of multiple modes. The measurement mode is equipped with a 7-inch large touchscreen color screen display and a fully Chinese menu. Each step has a Chinese prompt for the test results, which can be printed and output. Operators can proficiently use it without professional training.
