In three-phase applications, if there is low voltage available in one or two phases and you want your equipment to operate at normal voltage, this circuit will solve your problem. However, in the input lines (R, Y and B) of each phase, a suitable classification fuse must be used. The circuit provides the correct voltage in the same power lines through relays of the other phase where the correct voltage is available. Using it you can operate all your equipment even when the correct voltage is available in a single phase in the building. The circuit is built around a transformer, comparator, transistor and relay.
Energy instability in developing countries creates a need for automation of electric power generation or alternative energy sources to support the provision of public services. This automation is required as the rate of power cut becomes predominantly high. The commercial processes depend on the power source and if the change processes are manual, serious time is not only wasted, it also causes damage to the device or the machine due to human errors during the switching connections, which Could bring massive losses. The generator is started by a relay that switches the battery voltage to the generator ignition coil, while the main power relay switches the load to the public supply or to the generator.
