Abstract

SE DESCRIBE UN APARATO PARA MEDIR LA POTENCIA ELECTRICA EN DONDE EL APARATO SE ENCUENTRA ADAPTADO PARA GENERAR UNA SEÑAL DE SALIDA PROPORCIONAL AL PRODUCTO DE UNA TENSION DE ALIMENTACION (3) Y UNA CORRIENTE (1) QUE FLUYE A TRAVES DE UNA CARGA CONECTADA. SE UTILIZAN UNA PRIMERA SEÑAL (10) PROPORCIONAL A LA TENSION DE ALIMENTACION (3) Y UNA SEGUNDA SEÑAL (9) PROPORCIONAL A LA CORRIENTE DE CARGA (1) PARA MODULAR EL PERIODO DE DOS SEÑALES DE PORTADORA DE FRECUENCIA CONSTANTE. SE TRANSMITEN UNA TERCERA Y CUARTA SEÑALES (38, 39) DERIVADAS DE LAS SEÑALES MODULADAS A UN MICROPROCESADOR (8), POR EJEMPLO A TRAVES DE DISPOSITIVOS DE AISLAMIENTO ELECTRICO (6, 7). EL PROCESAMIENTO DE LAS TERCERA Y CUARTA SEÑALES PUEDE INCLUIR UNOS CONTADORES (88) Y LA GENERACION DE UNA SEÑAL DE RELOJ DE FRECUENCIA CONSTANTE. LAS SEÑALES SE PUEDEN PROMEDIAR DURANTE UN CIERTO PERIODO DE TIEMPO PARA OBTENER UNA CALIBRACION AUTOMATICA DE POTENCIA CERO.
