    Abstract: A medium- or high-voltage switching system for AC current comprising two series-connected switches substantially simultaneously opened by random operated opening means. The first switch is shunted by a series arrangement of rectifiers and of a thyristor having together a reverse voltage rated to withstand the restriking voltage across said first switch. Electronic trigger means feeded by the arcing voltage across the first switch and responsive to the current to be interrupted trigger said thyristor shortly before current zero in the appropriate half-cycle to commutate said current from the switch to the shunt path. The arcing interval of the first switch subsequentially deionizes and the opened second switch prevents application of the recovery voltage to the rectifiers.

    Abstract: A medium or high voltage three phase electric switching system comprising in each phase a pair of separable contacts shunted by a plurality of serially connected rectifiers. A special connection of the rectifiers of the different phases and a gated trigger circuit permit to select the number of serially connected rectifiers of two of the phases corresponding to only a fraction of the circuit interphase reverse restriking voltage.

    Abstract: Telemetering device for sensing an electrical quantity such as the current or the voltage associated with a high-voltage powerline. The rotation of the polarization plane of a polarized light beam directed from the vicinity of said powerline to ground and having traversed a magneto-optically or electro-optically transducer sensitive to said quantity is measured at a ground station where the light beam is divided in a pair of elementary beams directed to a pair of photoelectrical devices inserted in a measuring bridge. The bridge is balanced by a servomechanism controlled by the electrical error signal produced in the bridge under the influence of an independent second divided light beam.
