Explain how a reduced-voltage motor starter functions and the benefits it provides compared to an across-the-line starter.



A reduced-voltage motor starter is a device that starts an electric motor at a reduced voltage, gradually increasing the voltage to the motor's full rated voltage. This is in contrast to an across-the-line starter, which applies the full voltage to the motor immediately upon starting. When a motor is started across-the-line, it draws a very high inrush current, typically 6 to 8 times the motor's full-load current. This high inrush current can cause voltage dips in the power system, potentially affecting other equipment....
