Protection of electrical systems is a balance in reliability, security, sensitivity and speed. This course is intended for professionals working in the electrical industry who wish to develop skills in the area of electrical protection. The course is based on hands-on learning, using software to demonstrate the fundamentals of electrical protection and the different components of a protection system. Topics include: ac signal sources, key drawings used in protection, protection zones, types of protective relays (current, directional, impedance/distance and differential) and their applications, fault current calculations and the per unit system. Labs will be based on using PSCAD and ETAP software. Instruction on using the software will be provided during the lab periods.
