Protective Relay Training Fundamentals

This 2-Day Protective Relay�Training course provides a comprehensive understanding of industrial, commercial and institutional power system protection. Relay technicians, system protection engineers, consultants, and engineers and technicians working in system protection should take this course.

The course will benefit personnel of all levels of experience because it covers a range of complexity of relay schemes, methods of testing relays and of analyzing relay operations. We discuss system protection principles, measurement devices used for relaying, basic relay schemes used, and the most common schemes used in the field. This course provides professionals with real examples from actual system protection situations.

This course will cover relay theory and operation of the older electromechanical as well as the modern digital types, covering many types of functions such as overcurrent, over voltage, impedance and differential. Topics such as fault current basics and application of fuses and reclosers on distribution circuits and circuit breakers and instrument transformers in substations on distribution or transmission circuits or lines, will also be covered.

Gain valuable experience in utility and industrial electrical system analysis, protection, control, communication, and automation
Learn the latest trends in evolving electrical protection standards, design methods, and new technologies
Gain Valuable knowledge of electrical power system analysis and short circuit calculations, time current coordination curves, fusing fundamentals, and more!!
Learn how to keep your electrical system engineers, operators and project managers on track by using the latest relay protection techniques

Large or small, each and every industrial, commercial and institutional organization needs to understand how to protect their investment in their electric power systems. To do this properly, companies need to know how to perform an electrical protection analysis of all the parts of their power system: such as analyse fault data, come up with protection settings, then get all of the components of their plant to be controlled by the operators who are responsible for integrating their power system into communication and data acquisition modes.

Students will be learn the essentials of electrical protection design, relay coordination, and fusing fundamentals, breaker fundamentals. Students will be provided with an understanding of digital protective relaying, as we go through practical examples of generator, feeder, motor, and transformer electrical protection.
