Webto the system. To protect against surge events, it’s necessary to understand what determines the magnitude of both the voltage and current elements of the surge. The total energy in the originating event that caused the surge and the proximity of the originating event to the system under test determine the magnitude of the fault voltage. WebPhase Reversal Protection working Principle: The direction of induction motor depends on the direction of rotating magnetic field produced by the stator windings. These directions can be controlled doing phase reversal of the motor.
