20 Kv Digital Insulation Resistance Meter for Electrical Power Systems

20 kv digital insulation resistance meter for electrical power systems
 

I.overview
Hz 20kv Digital Insulation Resistance Tester, through the test system in different components of the insulation resistance (transformers, switching devices, wires, motors), you can isolate and repair the failure of components.
It is of great significance to ensure the safety of products and equipment in the quality of products and equipment by using insulation test to test the insulation between the sample and the adjacent conductor.
Before the system is powered by an insulation test verify that it is sound, can improve the performance of the system; insulation test can be found in manufacturing process and equipment defects, and these problems before the equipment failure is generally not found. In the EU, this testing is mandatory, even for the smallest civil system.

II.performance characteristics
