The HZJYY-JT Insulating Oil Dielectric Loss and Volume Resistivity Tester is designed and manufactured in accordance with GB/T5654-2007, "Measurement of Relative Permittivity, Dielectric Loss Factor and DC Resistivity of Liquid Insulating Materials." It is used to measure the dielectric loss factor and DC resistivity of insulating oils and other liquid insulating media.
The tester features an integrated structure that incorporates an oil cup for dielectric loss, a temperature controller, a temperature sensor, a dielectric loss test bridge, an AC test power source, a standard capacitor, a high resistance meter, a DC high voltage source, and other main components. Utilizing full digital technology, the instrument offers fully automated intelligent measurements and is equipped with a large 5.7-inch TFT full-color LCD touch display. The user-friendly interface and full English menu ensure that operators can use the instrument proficiently without specialized training. Test results can be automatically stored and printed.
