CONDUCTORES TRIFACICOS Vatímetro trifásico El vatímetro es un instrumento electrodinámico para medir la potencia eléctrica o la tasa de suministro de energía eléctrica de un circuito eléctrico dado. El dispositivo consiste en un par de bobinas fijas, llamadas «bobinas de corriente» o amperométrica, y una bobina móvil llamada «bobina de potencial» o voltimétrica. Las bobinas fijas se conectan en serie con el circuito, mientras la móvil se conecta en paralelo . Además, en los vatímetros analógicos la bobina móvil tiene una aguja que se mueve sobre una escala para indicar la potencia medida. Una corriente que circule por las bobinas fijas genera un campo electromagnético cuya potencia es proporcional a la corriente y está en fase con ella. La bobina móvil tiene, por regla general, una
