Dear sir,
How a protection system can distinguise between stalling and starting condition of an Induction motor?

Hello lalmehal,

Stall protection is a function that is generally not enabled until after the motor has reached full speed.

A locked rotor condition during starting will generally cause an overload or excess start time trip.
