Abstract :
The operation of a new algorithm for computing kVAh from kWh and kVArh pulse inputs is described. The algorithm works in close to real time within the meter register to enable display of kVA demand and power factor together with the usual kWh and TOU functions. The algorithm has been tested with pulse input trains representing randomly varying power factors for random periods of time and found to be accurate to within a few tenths of a percent
