A method/circuit for determining the continuity of a fuse comprising a first and second galvanic isolators and a fuse, signal-generation and signal-detection units, each communicatively coupled to a galvanic isolator. A signal is sent through the first galvanic isolator and received through the second galvanic isolator by the detection unit. A detection signal is generated indicating on whether the electrical signal is present in the closed circuit comprising the fuse. A circuit for determining the continuity of a fuse comprised in a ground fault detection circuit of a photovoltaic array is described. |
