摘要
The device (1) for measuring electrical parameters in a photovoltaic string (2) is provided with measuring means (3) for measuring at least one electrical parameter (V, I) of the string, which further comprises inductive means (4) for generating a supply current for the measuring means, and a through hole (5) adapted for the passage of an electrical power cable (6) through the device and through the inductive means for generating the supply current by the induction of a magnetic field induced by the electrical power cable during the passage of an electric current through the electrical cable.
