In the preventive insulation test of power equipment, it is required to measure the insulation oil parameters of power equipment periodically. The measurement of dielectric loss and resistivity of insulating oil is one of the most important. For a long time, most of them adopt the bridge method for measurement, which is complicated in operation and the measurement accuracy is affected by many factors, thus leading to a large measurement error. With the rapid development of electronic technology and the power industry for small volume, light weight, easy to operate, rapid measurement, high precision measurement instrument requirements, I refer to domestic and foreign related instruments developed in the domestic leading insulation oil dielectric loss factor and dc resistivity tester. The instrument is designed and manufactured according to gb5654-2007 and related standards. It is controlled by microcomputer, easy to use, high measurement accuracy, high test efficiency and greatly reduces labor intensity.
