shall be tested for short circuits between turns of the individual coils by
applying a high frequency voltage of not less than 75 percent of the
voltage for which the machine is insulated, or by applying a surge test
voltage of equivalent value to the terminals of each coil. Equivalent
surge voltage shall be a wave whose peak value is equal to 1.06 times the
voltage for which the motor is insulated.
