Abstract

Aparato y procedimiento para identificar la localización de un fallo en un banco de condensadores en derivación.#Se divulga un aparato y un procedimiento para identificar la localización de un fallo en un banco de condensadores en derivación. El aparato incluye un circuito de muestreo para el muestreo de señales de corriente o tensión asociadas con el banco de condensadores en derivación. Un microcontrolador está acoplado al circuito de muestreo y programado para medir un ángulo de fase de punto neutro compensado de la señal muestreada, y comparar el ángulo de fase de punto neutro compensado con un ángulo de fase de referencia fijo. El procedimiento incluye el muestreo de una señal de corriente o tensión asociada con el banco de condensadores en derivación, la determinación de un ángulo de fase de punto neutro compensado, y la comparación del ángulo de fase de punto neutro compensado con un ángulo de fase de referencia fijo.
