Power System Protection Training

Power System Protection

This Power System Protection Training course will provide a practical understanding of protective device applications and protective relay schemes for electrical power systems and equipment.

Refresh your knowledge of the basic industrial system protection techniques including fault analysis and overvoltage assessment. Develop your own relay settings and thoroughly understand the philosophy of protective systems. Study actual cases illustrating various techniques in present use and highlighting particular approaches used by experienced system designers. Enhance your experience with power system protection problems generally faced, and solutions successfully adopted, by industry. Understand how to apply microprocessor-based multifunction relays for the protection of various power system equipment and apparatus.

Power System Protection Training teaches students how to make sure that  downstream devices (breakers/fuses) should activate before upstream devices and therefore protect their electrical systems. By doing this, it minimizes the portion of the system affected by a fault or other disturbance. At the substation level, feeder breakers should trip before the main. Likewise, downstream panel breakers should trip before the substation feeder supplying the panel.

Power System Protection And Coordination of various electrical equipment and apparatus requires a good understanding of phase and ground short circuit currents, detection, and safe clearing of the faulted equipment. This Power System Protection And Coordination Training Course provides a practical and comprehensive description of the principles and concepts of analysis, application and operation of protection schemes for various power system elements such as feeders, transformers, motors, buses, generators, etc. The Power System Protection And Coordination Training course starts with an overview of power system fundamentals, design and short circuit calculations which lead to the understanding of protection scheme requirements and their applications. Protection requirements for industrial plants, cogeneration, and interconnection with the utility power system are explained in detail. This course covers the subject of power system protection from a practical perspective, and includes important functional aspects such as testing and coordination of protection systems. This course is designed for individuals who are involved with industries and utilities which depend on proper system protection for operational efficiency and minimizing damage to equipment.
