Abstract

Procedimiento para compensar la corriente de fuga en una instalación fotovoltaica, que comprende los pasos siguientes: - detección de una corriente de referencia que circula hacia tierra a través de una capacidad (C1, C2) desde al menos una línea conductora de corriente (8, 9, L1, L2, L3) sometida a tensión. - generación de una corriente de compensación con la fase y la frecuencia de la corriente de referencia y con una amplitud adaptada frente a la corriente de referencia por un factor de escalado negativo -G; - detección de una suma de corriente (18) con ayuda de un primer sensor de corriente diferencia (16), siendo los sumandos de la suma de corriente (18) las corrientes circulantes por un juego completo de líneas conductoras de corriente (8, 9, L1, L2, L3, N) y - contenida en ellas o separada - la corriente de compensación; - minimización de la suma de corriente detectada (18) por adaptación del factor de escalado -G; caracterizado por - conducir la corriente de compensación por al menos otro sensor de corriente diferencia (5) de modo que la corriente de compensación compense una porción de corriente de fuga en una corriente diferencia vigilada con el otro sensor de corriente diferencia (5).
