Summary

This report deals with overvoltages and overvoltage protection in the generator main electrical circuit in power stations. it includes earthing practice of the generator circuit, such as neutral point treatment of generator and generator transformer. Different kinds of overvoltages are described, together with their origin. Methods for calculation of overvoltages are presented as well as protection systems to minimise the effects of overvoltages.
