What is a liquid resistance starter?where it is used??
Answer Posted / gopal
Combination of water and castic soda for improving the
resistance in starter, i.e. called Liquid Resistance
starter.
If any slip ring Induction motor, at the time of starting
given the external resistance required to rotor side, why
because starting current and startying torque is very high.
So we are using resitance starter.Depend on motor
capacity , at that place using Liquid resistance starter.
