What would be the Field DC Hi-Pot Voltage for a Visi/Vac Circuit Interrupter? How is this value calculated?

The field test voltage is 75% of the factory test voltage. At 15kV the factory AC test voltage is 36kV. .75 times 36kV is 27kV AC field test voltage. The DC test voltage is 1.414 times the AC test voltage. 1.414 times 27kv is 38kV. This is the DC Hi-Pot value for the Visi/Vac field test.
