Abstract :
The windings of large induction motors and also some synchronous machines with power ratings ranging from a few hundred to several thousand kilowatts, are often subjected to very high stresses in service, for instance under direct online starting or short circuit conditions or during sudden system changeover. Additionally there exists a trend to subject such machines to high contamination or humidity conditions without any extra protection.
