Switching circuit for a bistable magnetic actuator

A switching circuit for a two-coil bistable magnetic actuator, e.g for a reclosing circuit breaker, uses two switching devices 11,12, such as MOS or bipolar transistors, and freewheel diodes 23,24 which are switched out of circuit when an activating signal is being applied to the other of the transistors, but switched into circuit when the transistor with which they are coupled is turned off. If the diodes were left in circuit they would reduce the actuator's speed of response by allowing an induced circulating current to flow, opposing armature movement. The diodes 23,24 may be switched into circuit by normally open contacts 32,33 which are closed by the coils 30 and 31. A suitable relay response time response time (e.g. 5 ms) ensures that the diodes are in circuit for a sufficient time to absorb most of the magnetic energy of the magnetic actuator, thereby protecting the transistors from damaging overvoltages. The metal oxide varistors 20,21 also absorb some of the magnetic energy.

Fault detection for n phase electrical measurement - using two sets of metering one set of comparators and two sets of homopolar units

Electrical quantities such as voltage are metered for each phase of a system by a set of meters (A1) (A2) (A3). One set of check meters (B1) (B2) (B3) are also installed and comparators (CP1, CP2, CP3) check that both meters on each phase agree. A homopolar unit (HA) (HB) produces the vector sum of each set of meter readings and compares the result with preestablished values. Operation of a comparator (CP) for a particular phase together with operation of one homopolar unit for a particular set of metering identifies one meter uniquely as faulty. ADVANTAGE - Combination of comparators and homopolar units enables benefits of triple redundancy to be obtained with only two sets of metering.
