Electrical Protection Systems and Equipment

Electrical power system is a vital element in any industrial operation. Regardless of how well the system is designed and built, freedom from equipment failure cannot be guaranteed. A good protection system will minimize damage to the faulted equipment and system while maintaining service to the remaining system. This course covers the basic principles of protection systems and the arrangement of various protection systems for typical power system components.
