    摘要: An arrangement is made in a transformer such that voltages induced on the opposite sides of a mid-point 17 of a secondary winding 16 are unbalanced by an amount on the order of 5%. When a ground terminal 18 is not grounded while a mid-point of a load is grounded, a voltage VUE is developed between the mid-point 17 and a non-active line terminal 15 and is rectified to provide a rectified output which turns a transistor 28 on, causing a light emitting element 33L to emit light. The resulting light renders a light receiving element 33P conductive, whereby a relay 37 is operated to turn a switch 13 off. When a ground fault occurs on one side of the secondary winding 16 while the ground terminal 16 is not grounded, a ground fault detection circuit 38 fails to detect the ground fault, but the non-grounding protection circuit 30 detects the ground fault and turns the switch 13 off.

    摘要: A neon transformer includes secondary windings 16 and 17, and a junction 20 therebetween is connected through a voltage detection circuit 41 to a ground terminal 18 of the transformer. A resistive element 54 is connected in shunt with the voltage detection circuit 41. The voltage detection circuit 41 may comprise a series circuit of a Zener diode 52 and a light emitting element 53L of a photocoupler, for example. When a ground fault occurs on the secondary side of the transformer, the location of the ground fault assumes a reference potential, whereby the potential of the junction 20 rises to cause a current flow through the Zener diode 52 and the light emitting element 53L, which renders a light receiving element 53P conductive to pass an energizing current through a relay drive coil 34, thus throwing a relay contact switch 13 from NC to NO, thus interrupting the supply of the a.c. power.

    摘要: An abnormality detection circuit detects abnormality relating to ground fault in secondary winding circuitry of transformer, non-grounding fault of transformer assembly casing or false connection of the AC power source to the transformer assembly in reverse polarity. An interrupter circuit turns a switch off in response to detection of the abnormality by the abnormality detection circuit to interrupt the supply of the AC power to the transformer. When the supply of the AC power is interrupted, the switch is connected to a restart circuit, whereupon the circuit is activated to allow a charging current to flow to a capacitor, which is connected in series in a drive current path of a drive circuit with a time delay on the order of 0.5 to 1.0 second which is determined by a delay circuit thereof. The charging current drives a restoring circuit, which controls the interrupter circuit to its restoring condition temporally so that the switch is turned to its “on” condition only once.
