A variable resistor R2 is connected in parallel with the relay coil 1 for adjusting the operating voltage, and a capacitor C1 may be connected as shown for smoothing. Rectifiers 3, 4 are included in the lines A, B. The second impedance network comprises resistors R3, R4, a choke 5 and a capacitor C2. The potential difference between the point 6 and the line C is zero if the phase-rotation of the supply is correct. This point is connected to the centre point 7 of a centre-tapped backing coil 8 through a D.C. blocking capacitor C3. The coil 8 is connected across a resistor R5 through oppositely connected rectifiers 13, 14. The resistor R5 is connected in series with a resistor R6 between the line C and the relay coil 1, so that if any error in phase-rotation is present the relay is energized and actuates an indicating instrument. The relay is also operated if there is voltage asymmetry in the network or if the voltage in the system falls below normal. The relay coil may be replaced by a control element that is arranged to pass a signal to a restoring means associated with the supply so as to actuate it in the sense to restore the balance.
