Protection of induction motors and generators is provided to allow rapid reclosure of the power supply or fast transfer from one power supply to an alternate supply. A switching sequence is disclosed in which motor stator windings are short circuited immediately following interruption of the supply voltage. Said short circuit quickly discharges to a safe value the energy stored in the rotor of the induction machine, allowing the short circuit to be removed and safe reconnection to the power supply to be accomplished without further delay.
