In energy meter there r 2 CT's are used.One for recording
current through incoming phase & other through outgoing
phase .When the load is ON on outgoing side the current
flowing through both CT's is compared by electronic
circuit.An wattmeter is calibrated as per standards which
measures wattage proportional to current.
