Appendix D — Recommended Test Voltages

Recommended DC Voltages for Insulation Resistance Test

EASA AR100 and IEEE 43 sections 5.4 and 12.2 provide guidelines on voltage to be applied during Insulation Resistance
(IR) testing. Test voltage should be applied for one minute.

Recommended DC HiPot and Surge Test Voltages

Megger Baker Instruments has a recommended standard (see table) for test voltages for DC tests and Surge tests
conducted on a motor, generator, or transformer. That standard is twice the AC line voltage plus 1,000 volts.

This test voltage is consistent with NEMA MG-1, IEEE 95-1977 (for test voltage greater than 5,000 volts) and IEEE 43-
2000 (test voltages less than 5,000 volts).

View other standards in the tables below for a comparison of IEEE 95, EASA DC-HiPot, IEEE 522 Surge testing, IEC 34-
15, and Megger recommended testing voltages.

NOTE: The tables list representations of motors, as well as the formulas to calculate voltages so that you
can calculate test voltage of any size motor.
