Metering of Active Electric Power in Three-Phase Four-Wire System in Non - Symmetric Regime

Node potential method has made it possible to justify that a three-phase meter of active energy is metering the whole consumed active energy at non-symmetric regimes of three-phase four-wire grid of 0,4 kV. The paper considers problems of non-balance in the readings of active energy meters installed...

Description
Summary:Node potential method has made it possible to justify that a three-phase meter of active energy is metering the whole consumed active energy at non-symmetric regimes of three-phase four-wire grid of 0,4 kV. The paper considers problems of non-balance in the readings of active energy meters installed , at different points of the 0,4 kV grid with non - symmetric regimes. In order to determine the rate of three-phase four-wire 0,4 kV grid non-symmetry it is suggested to introduce an additional criterion for the current GOST (All-Union State Standard) that is a magnitude of neutral wire current which can be easily determined for practical calculations.
