The fully automatic dielectric loss and resistivity tester for insulating oil is designed and manufactured according to GB/T5654-2007 Measurement of Relative Permittivity, Dielectric Loss Factor and DC Resistivity of Liquid Insulating Materials. Used for measuring dielectric loss factor and DC resistivity of insulating oil and other liquid insulating media.
Integrated structure. The main components, such as dielectric loss oil cup, temperature controller, temperature sensor, dielectric loss test bridge, AC test power supply, standard capacitor, high resistance meter, DC high voltage source, are integrated internally. The instrument is equipped with a 5.7 inch TFT pure color LCD touch display with a large screen and a Chinese menu. The test results can be automatically stored and printed out. The operators can skillfully use them without professional training
