explain why direct on line starting toque and current may

Answer Posted / vdw
If a system needs high starting torque then corresponding motor will draw very high current, in such a case it may get overload or probably causes electrical flash which is not acceptable. The remedy for this is to use star delta starter for the motor so initial current drawn by motor will be within safe conditions of motor.
