Why is there a difference when calculating power P(W) and Q( Var) when changing the phase sequence (acb)? Specifically between using the two- wattmeter method and using a smart meter? My true power P ( W) remains the same but the reactive power Q (Var) changes dramatically between the two- wattmeter method and smart metering.
