Course Description
This 5-day workshop is designed to provide excellent understanding on both a theoretical and practical level to attendees. The workshop starts at a basic level, to ease the engineer and technician into the perhaps forgotten art of studying, and provide a refresher to those who are more familiar with the basic topics covered.
This course focuses mainly on the operation and maintenance of Generation and distribution equipment with reference to auxiliary equipment necessary for its operation.
Maximum efficiency, reliability, and longevity of electrical distribution equipment such as the various type’s transformers, generators, circuit breakers, fuses, and power station electrical and protective systems are of great concern to many industries. These objectives can only be achieved by understanding the characteristics, selection criteria, common problems and repair techniques, preventive and predictive maintenance. This course is a MUST for anyone who is involved in the selection, applications, or maintenance of electrical equipment. It provides the latest in technology. The course covers how this equipment operates and provides guidelines and rules that must be followed for a successful operation. Their basic design, operating characteristics, specification, selection criteria, advanced fault detection techniques, critical components as well as all maintenance issues are covered in detail.
An overview of power system layouts, configurations, faults and the protection scheme requirements for the detection and coordinated clearance of these faults will be covered in more details. This course deals with protection systems from a practical perspective, and includes important functional aspects such as testing and coordination of protection systems. It is specially designed for industries and utilities, which depend on proper system protection for operational efficiency and minimizing damage to equipment.
