Course Description
Power system protection is an essential component of all forms of electrical power systems. In practice, protective relaying is directly associated with security of supply, the reduction of damage to faulted plant, cost of energy and, most importantly, all aspects of safety. The subject is unique in requiring knowledge of all topics broadly classified under the title of electrical power engineering, including generation, utilization, maintenance and the transmission of electrical power. As a consequence, it enhances an engineer €™s working knowledge and becomes an important asset for power system planning, operation and management.
The Training Course Will Highlight ?
The course focuses attention on the fundaments of the subject and illustrates the protection philosophies in common use by reference to the application of modern multi-functional microprocessor relays to practical situations.
