Our Substation Relay Protection Training is a 12-hour, instructor-led live online course designed for utility and industrial professionals involved in protective relay design, installation, testing, or maintenance. This course is ideal for electrical engineers, substation technicians, and system protection personnel who need a deep, practical understanding of relay protection principles across key substation assets.
Participants will gain applied knowledge of how relay protection systems safeguard transmission and distribution lines, transformers, buses, generators, and motors. You'll explore the function, coordination, and implementation of relay types such as overcurrent, directional, impedance (distance), differential, underfrequency, and generator protection relays. Real-world considerations and common challenges will be discussed, helping learners apply protection strategies effectively in the field.
This training emphasizes the theoretical foundations of relay protection and the practical tradeoffs, constraints, and modernization trends, including the growing role of data communications and substation networking technologies like IEC 61850.
