With the continuous updating and development of modern technologies, higher requirements are put forward for the reliability of power systems and Gaodianya equipment. Accidents or damage to electrical equipment are usually closely related to the defects of insulation. The large capacity, high voltage, diversified structure and sealing of electrical equipment should be updated and higher requirements. The use of large-capacity equipment continues to increase, and the insulation performance of ordinary megabytes can not be detected.

The power test rules require a series of insulation performance tests for many power equipment such as cables, motors, generators, Transformers, Transformers, high-pressure switches, and lightning absorbers. The first step is to do insulation resistance tests.

When testing the insulation resistance of large-capacity power equipment, the insulation resistance value is related to the pressure time. The longer the pressure time, the higher the insulation resistance value. This phenomenon is called the insulation absorption phenomenon. To understand the insulation performance of the sample, we must first do absorption ratio and polarization index test to provide safety guarantees for the next step of leakage, medium loss, partial discharge, etc.. Insulation performance test. In accordance with the power standardization regulations, our company has introduced a double display tester of high capacity, high anti-interference, and stable performance of intelligent insulation resistance, and conducted insulation, absorption ratio, and polarization index tests on power equipment to provide accurate judgment for the series of insulation tests.
