Introduction AC power transducer converts ac current and voltage signals into a load independent dc signal proportional to active power (watt) and reactive power (var). Two output signals combination in one transducer. The current and voltage signals are passed into the circuit via precision instrument transformers to provide galvanic isolation between the input circuits and the transducer circuitry. Each pair of current and voltage signals is mathematically multiplied together to produce a product signal proportional to true power and independent of wave shape and phase angle.
