    摘要： A protection system for protecting the secondary windings of current transformers against overvoltages. The protection system consists of a device shunting the secondary winding and having a triggering device operative when the winding is subjected to a voltage higher than the voltage appearing across the terminals of the secondary winding, under normal operating conditions and during a fault on the HV power network. The shunting device comprises a latching relay incorporating a coil which is energized by the triggering device to short-circuit the current secondary transformer through the relay contact, and, also, a voltage regulator connected in parallel with the relay coil. This protection system is simple, compact, lightweight and consumes no energy when the current transformer operates under normal conditions.

    摘要： A steering system used in a ground-engaged vehicle having independently motorized steerable wheels, where a steering assistance is provided by generating a differential torque in the motors for producing steering assistance forces, is disclosed. The steering assistance is provided, when a torque is applied on the steering wheel, by generating the differential torque by the motors and thus producing steering assistance forces due to virtual lever arms defined between the mean contact point of a wheel with the ground, and the virtual intersection with the ground of a prolongation of the pivot axis of the wheel.

    摘要： A semaphore for use in a detection system for a high voltage device and for signalling a predetermined state of the device. The semaphore comprises a housing supporting therein a retroreflector element. The housing has an aperture and the retroreflector has a reflective surface supported in a alignment with the aperture. The housing is mounted in close proximity to the device. A linkage is associated with the housing and the device and is actuated upon the occurrence of a predetermined condition whereby to expose the reflective surface in the housing for the reflection of signals through the apertures. A remote scanning device continuously generates infrared signals in the direction of the aperture and detects reflective signals from the reflective surface.

    摘要： A signalling system to indicate the position of a disconnect switch used in an electric transmission line. The switch has at least one moving contact and at least one fixed contact. The system comprises two transmitters associated with the moving and fixed contacts to transmit at least one ultrasonic signal indicating the position of the moving contact with relation to the fixed contact of the disconnect switch. A receiver assembly receives the ultrasonic signal transmitted by the transmitters and generates an output signal representative of the position of the moving and fixed contacts.
