https://www.mktester.com/transformer-oil-tester/oil-dielectric-loss-test-system.htmlOVERVIEW#65306;
Oil dielectric loss test system, is designed and manufactured based on GB/T5654-2007 of#12298;Liquid insulating material of relative permittivity, dielectric loss factor and DC resistivity measurements#12299;. It is used for measuring dielectric dissipation factor and DC resistivity of insulating oil and other insulating liquids. The instrument is characterized by integrated structure, and integrates test cell, temperature controller, temperature sensor, dielectric loss test bridge, AC test power, standard capacitor, high resistance meter, DC high voltage source and other major components. The instrument adopts full digital technology and all of the intelligent automatic measurement, is equipped with large colcor screen (800*480) LCD display, which each step has prompted the Chinese, the test results can be automatically stored and printed output, so that the operator without professional training will be able to use it proficiently.
