I.M are two types.slip-ring and Sq.cage type motors. in
cage motors windings are in the form of short circuited
conducter bars. which have high reactance, due to at the
time of staring they will draw more reactive power and
having less straing torque.
*** in slip ring induction motors we add extra resistance
to reduce drawing high current at the time of starting and
improves starting torque.
**** main use of Slip rings is improving starting torque.

I have a relay contact rated at 220v dc which is supplied with a 24vdc from the panel,for it to trip the dampers(24vdc).What if the application of the relay changes so that it should work at its rated 220vdc then will it work at 24vdc supply given or any other consideration needs to be taken .....
Consider three heater bank connected in 3 phase star with neutral.Each heater bank connected in each phase.So each phase get 230 volts supply.my question is,during balance condition, current flow in neutral or Not
a)In a 3-phase 4-wire circuit, a circuit breaker is selected to protect the circuit whose highest fault level is 6.6 MVA. Determine the required minimum breaking capacity in kA. (Note: Covert 3-phase power in terms of kA to find answer.) b)Using the below, determine the required minimum making capacity in kA as a “peak value”. Rate breaking capacity (Icn) ka: Icn<= 1.5 Factor = 1.41 1.5
