8 Motor Testing and CBM
AC and DC High Potential Tests
While the Insulation Resistance, Polarization Index and Dielectric Absorption tests are methods of evaluating general insulation to ground condition, the high potential test is a method of evaluating insulation to ground integrity, or dielectric strength. There are two basic types of high potential tests: AC and DC, of which we will cover both in today’s presentation.
