[Class 38 (ii).] Relates to the overload protection of circuits using grid controlled discharge devices by the application of a negative holding potential to the grids. A.C. circuits 1, 2 are interconnected through a D.C. circuit 3 and valves 11-16, 21-26. The grids of the valves 11-13 are supplied with control potential from a transformer 4 connected to the supply 1 through a phase shifting transformer 5. A resistance 20 connected between the star-point of the transformer 4 and the cathodes of the valves 11-13 is in parallel with a resistance 19 in the anode circuit of a discontinuous control valve 7 the grid of which is connected through a negative bias battery 8 to the secondary of a current transformer 9 coupled to the supply network 1. When the load current exceeds a predetermined amount, adjustable by means of the resistance 17, the valve 7 becomes conductive and applies a negative potential to the grids of the valves 11-13 sufficient to prevent operation. This is maintained until the anode circuit of the valve 7 is broken. In a modification the valve 7 is controlled by the potential drop in a resistance in the D.C. circuit 3. The Specification states that the system may be arranged so that the holding potential is applied in the event of failure of voltage in supply circuit 1.
