Connecting your Insulation Test Set

DC Hipots and Megohmmeters are fairly common test sets used by test technicians and engineers.  The basic operation for both a DC Hipot and a Megohmmeter is the same; a known DC voltage is applied across insulation.  The applied potential causes several small currents through and over surfaces of the insulation being tested. The total current is measured and the result is displayed as either an ohmic value or as a current value.
