MEASURING REACTIVE POWER IN ENERGY METERS
METERING INTERNATIONAL ISSUE 1 200252 REACTIVE ENERGYThis change in the end-consumer profile is adisadvantage for ENERGY distributors which billenergy based only on active POWER . With theapplication of non-linear loads to POWER linesthe active ENERGY no longer represents thetotal ENERGY delivered. As a response toimprove billing, the measurement of reactiveenergy is gaining interest. For example, Italy sleading ENERGY distributor has decided toinstall more than 20 million household energymeters with active and REACTIVE growing interest in MEASURING reactiveenergy leads to the question: What methodshould an ENERGY meter designer implementto accurately measure the REACTIVE ENERGY ?Although today s electronic digital signalprocessing (DSP) enables REACTIVE energymeasurements to be closer to the theoreticalvalue, there is no consensus in the field ofenergy metering on the methods ofmeasurement.
