Calculate the number of required pulses
Normally, the number of pulses required is at least 25 pulses, and the test duration is greater than 30 seconds.
Use the following formula to calculate the required number of pulses:
Calculation for number of required pulses
This example calculates the number of pulses required for an inductive load 3-phase test point with a test duration of 60s; the source is configured to use V = 120V, I = 5A, PF = -0.5; the pulse constant of the meter under test is Kt = 1.8 Wh/pulse.
Round the number up to the nearest integer: Number of pulses = 9
