This is a calculater for electrical engineers which will give you information that how motor will react when you will start it by DOL method and when you will start it by Star-Delta method.
Capacitors must be built to tolerate voltages and currents in excess of their ratings according to standards. The applicable standard for power capacitors is IEEE Std 18-2002, IEEE Standard for Shunt Power Capacitors.
This slide speaks about that how motor operation fails due to heat. how heat affect motors?
