Abstract

The authors propose a method for measuring of asymmetrical three-phase loads, based on the principle of action is laid on the integration of the instantaneous power of a sliding time interval lasting half a period of supply voltage. Measuring channel has sufficient stability and is characterized by the absence of systematic errors of measurement in the presence of three-phase voltage unbalance and higher harmonics of load current
