Phase changers guarantee continuity of power supply to single-phase receivers if 3-phase mains are available. Decay of voltage in hot phase of power supply to the equipment causes automatic switch-over to the other phase. Once the supply voltage has been re-applied, the relay may switch over the power supply to the phase selected as the basic one or remain in the phase of the best voltage characteristics. Please note that during switchover, a second break in power supply occurs, and therefore, the devices which are vulnerable to such a short power interruption (e.g. computers) should be additionally protected by battery supported uninterruptible power supply unit (UPS).
