Their place of installation is usually located at the start or end of a long overhead power line or cable connection, or in central substations.

Motor soft starter - Wikipedia

WebA soft starter continuously controls the motor's voltage supply during the start-up phase. This way, the motor is adjusted to the machine's load behavior. Mechanical operating equipment is accelerated smoothly. This lengthens service life, improves operating behavior, and smooths work flows.
