Product Introduction

In the preventive test of electrical equipment insulation, periodic measurement of insulating oil parameters of electrical equipment is required. The measurement of dielectric loss and resistivity of insulating oil is one of the most important items.With the rapid development of electronic technology and the electric power industry’s requirements for measuring instruments with small size, light weight, convenient operation, rapid measurement and high precision, our company is based on the national standard GB/T5654-2007/IEC 60247-2004 “Liquid insulating material relative capacitance,measurement of dielectric loss factor, dielectric loss factor and DC resistivity”, and with reference to related instruments at home and abroad, we have developed a domestically leading high-precision integrated insulating oil dielectric loss factor and DC resistivity tester. It utilizes precision technology to rapidly and accurately assess the dielectric loss and resistivity of insulation oil, widely applied in transformers, switchgear, and other areas.
