The most common function of reduced voltage starting devices is to reduce the starting current of an induction motor. This is achieved by reducing the voltage applied to the motor during the starting period, which in turn reduces the current drawn by the motor. This is important because the starting current of an induction motor can be several times higher than the rated current, which can cause voltage drops in the system and damage to the motor and other equipment. By reducing the starting current, reduced voltage starting devices help to extend the life of the motor and improve the reliability and efficiency of the system. Reduced voltage starting devices, such as soft starters and autotransformers, are used to gradually increase the voltage and, as a result, reduce the starting current of an induction motor. This reduces the electrical and mechanical stress on the motor and its components, and also reduces the impact on the power supply system.
