INTRODUCTION
The course is intended to provide electric engineers with collective and recent knowledge about generators exciters including: ordering specifications, operation, analysis, maintenance, testing and protection.
A generator is subjected to electrical traces imposed on the insulation of the machine, mechanical forces acting on the various parts of the machine, and temperature rises. These are the main factors which make protection necessary for the generator or alternator. Even when properly used, a machine in its perfect running condition does not only maintain its specified rated performance for many years, but it does also repeatedly withstand certain excess of over load. Hence, preventive measures must be taken against overloads and abnormal conditions of the machine so that it can serve safely. Despite of sound, efficient design, construction, operation, and preventive means of protection, the risk of that fault cannot be completely eliminated from any machine.
The devices used in generator protection, ensure the fault, made dead as quickly as possible. It is imperative need to install some protective system to protect the expensive elements of the generator from different types of faults which are likely to occur sooner or later.
