High Potential (Hi Pot) | Specialized Engineering Services, Inc.

The Basic test Voltage for Hi Pot testing is the 2X (Operating Voltage) + 1000 V. The reason for using 1000 V as part of the basic formula is that the insulation in any product can be subjected to normal day-to-day transient over voltages.
