ABSTRACT:
High-voltage high-power, multiphase electrical installation comprising, for each phase, at least two circuit fields that include, in each circuit field, a circuit breaker arranged between two current transformers, each of them discharging into the same load as the homologous current transformers of the other circuit fields having the same phase; isolating switches placed at the ends; earth isolators placed between the isolating switches and the current transformers. The magnetic circuit of the current transformers is crossed simultaneously by the conductor of the phase of the circuit field and by an auxiliary conductor connected; on the one hand, to a ground isolator and, on the other hand, to a ground point.
