grinding machine insulation resistance value

Types Of Tests - Electrical Equipment Testing | Metrotest

Insulation Resistance Tests must not be carried out using Ohmmeters or Multimeters because these meters only produce a small battery voltage in the region of 1.5 to 9 volts. This small voltage is insufficient to pressure test the insulation to expose any weakness in it and therefore is totally inappropriate for Insulation Resistance Tests.
