Abstract :
An electronic reactive energy meter whose principle of operation is completely in accordance with the IEC definition of reactive energy is introduced. By applying a simple integrating circuit as a phase shifter at the voltage input and consequently modifying the power to the frequency converter, a simple but high-performance metering system is achieved. This meter is suitable for measurements in three-phase and single-phase systems.<>
