Required pulses calculation for accuracy verification testing
The reference test equipment typically requires you to specify the number of pulses required for a test duration of “t” seconds. 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:
Number of pulses = Ptot x K x t/3600
Ptot = total instantaneous power in kilowatts (kW)
K = the meter’s pulse constant setting, in pulses per kWh
t = test duration, in seconds (typically greater than 30 seconds)
