ABSTRACT:
A system for the floating energization of a balanced load from a remote power supply via a pair of conductors, e.g., for feeding operating currents to repeaters of a telecommunication link, includes a circuit breaker controlled by an open-circuit sensor and an unbalance sensor through a memory unit provided with a pair of storage circuits. These circuits, designed to store a malfunction signal emitted by either of the two sensors until the arrival of a resetting signal, inhibit each other to prevent the registration of more than one malfunction at a time.
