A Short-Term Power Fluctuations Averaging In Low Voltage Ac Grid

In the paper a procedure of short-term measured power samples optimal averaging period tracking is proposed. Usually, short-term (in the scale of fraction of a second) power consumption fluctuates due to operation of variety of network connected switching mode loads. The aim of the suggested tracking procedure is to reduce averaged power measurements statistical deviation in AC electrical distribution network. Reduction of deviation of power estimates is important prerequisite for implementation of remote watthour meters or smart-sockets calibration or verification.
