The
power factor is to be determined by referring the open-circuit voltage wave to the two adjacent zero points
at the end half of the first complete current cycle by transposition through an appropriate timing wave –
the power factor to be computed as an average of the values obtained by using these two current zero
points and the voltage to neutral to be used in the case of a 3-phase circuit.

The System Voltage
used in the evaluation of secondary circuitry may be interpolated with interpolation continued
across the table for the Rated Impulse Withstand Voltage Peak and Clearance; and
