EE 205 Dr. Chokri. Belhaj Ahmed - 3 - Introduction to the Wattmeter ± To measure power in three phase circuits, the wattmeter is used basic instrument. ± It contains two coils, the current coil and the potential coil . ± The current coil is stationary , it is designed to carry a current proportional to the load current. ± The potential coil is movable , it carries a current proportional to the load voltage. ± A pointer is attached to the potential coil.
