As soon as the first mill motor is started and bypassed to the line, the drive is available to start the second mill. The same process is repeated to make the drive available for starting the third mill. All three mills can operate directly across the line, or one can remain connected to the drive for variable frequency operation if required.

The liquid resistance starter, also known as liquid rheostat (LRH), is programmed to drive the electrode downward as the motor accelerates to reduce the resistance approximately proportional to the reduction of secondary voltage. This will enable the motor to maintain the rotor current relatively constant during the acceleration of the motor.

Liquid rheostats used as motor start switches, circa 1900. A liquid rheostat or water rheostat or salt water rheostat is a type of variable may be used as a dummy load or as a starting resistor for large slip ring motors.. In the simplest form it consists of a tank containing brine or other electrolyte solution, in which electrodes are submerged to create an electrical load.
