Solid Insulation Material Testing

 

Routine testing of vacuum pressure impregnated (VPI) and resin-rich (RR) insulation materials, as well as insulation tape-bands and paper insulation used in electrical machines, such as generators and motors, or transformers, should be tested regularly and properly.

The most important tests to conduct are tan delta, capacitance, and breakdown voltage. Testing of these material properties can help in research and development of new insulating materials or to ensure quality control following production.
