Product Introduction

This product is a high precision instrument with integrated structure for measuring dielectric loss Angle and volume resistivity of liquid insulating medium such as insulating oil.Internal integration of dielectric oil cup, temperature controller, temperature sensor, dielectric test bridge, ac test power supply, standard capacitor, high resistance meter, dc high voltage source and other main components.The heating part adopts the most advanced high-frequency induction heating method, which has the advantages of non-contact between oil cup and heating body, uniform heating, fast speed and convenient control.AC test power supply adopts ac-dc-ac conversion mode, which can effectively avoid the influence of voltage and frequency fluctuation of mains electricity on the accuracy of dielectric loss test, and the instrument can run correctly even when the generator generates electricity.The internal standard capacitor is SF6 gas-filled three-pole capacitor, whose dielectric loss and capacitance are not affected by ambient temperature and humidity, etc., so as to ensure the consistent accuracy of the instrument after long use.

The instrument is equipped with a large screen (320×240) touch-controlled display, a full Chinese menu, and Chinese hints for each step. The test results can be printed out, and operators can use it skillfully without professional training.

Warning: the company reminds the user that the device has high voltage output, which may endanger personal safety if not used properly!

The product names:Oil Dielectric loss tester for oil, insulating oil Dielectric loss tester, Dielectric loss tester, insulating oil Dielectric loss tester
