What is Power Factor Meter Overview and Types about?

Power factor meters measure the power factor in AC circuits more accurately than just dividing power, current, and voltage. They have two coils - a pressure coil connected across the circuit and a current coil that carries some fraction of the circuit current. The phase difference between the voltage in the pressure coil and current in the current coil is used to calculate the power factor. Modern power factor meters are either electrodynamometer type or moving iron type, with the electrodynamometer type ha
