Product Introduction By testing the insulation resistance of different components in the system (transformers, switching devices, wires, motors), faulty components can be isolated and repaired.
High-voltage insulation resistance tester uses insulation test to verify that the insulation between the test object and the adjacent conductors is of great significance to ensure the product quality and the safety of people and equipment in operation.
Before powering up the system, verify it is sound using insulation tests to improve the performance of the system; insulation testing can identify manufacturing process issues and equipment defects that are generally undetectable before the equipment fails. In the European Union, this test is mandatory, even for the smallest civil systems.
In the insulation test, the insulation resistance value at a certain moment cannot fully reflect the good or bad of the insulation performance of the sample. This is due to the insulation material with the same performance, the insulation resistance presented when the volume is large is small, and the insulation resistance exhibited when the volume is small is large; The insulating material has a charge-absorption ratio process and a polarization process after the high voltage is applied. Therefore, the power system requires that the absorption ratio (R60s and R15s ratio), and the polarization index (R10min and R1min ratio) should be measured in the insulation test of the main transformer, cable, motor and other occasions, and the insulation status should be determined as excellent. inferior.
Absorption ratio and polarization index are in the same test. The ratio of insulation resistance at 60 s to insulation resistance at 15 s (R60S/R15S) is called absorption ratio.
In the same test, the ratio of the insulation resistance at 10 minutes to the insulation resistance at 1 minute (R10min/R1min) is called the polarization index.
