An online intensive professional development training course on

Power System Protection

Fundamentals and Applications of
Protection Devices Selection and Coordination

Why Choose this Online Training Course?

Reliable, safe and secure power system protection is essential as the demand for electrical energy has increased exponentially. Electrical protection devices and their associated instrumentation components should be designed accurately with zero tolerance error. Numerical relays are fundamental and critical aspect of digital electrical installations besides the conventional fuses and circuit breakers. Protection is applied on a component or equipment basis. Relays are associated with each major component of the power system to detect various forms of distress associated with those components. If one of those relays operates, which means that an output contact protective devices activate followed by isolating the defective system components.

State of the art power system protection with internet of things (IoT) and artificial intelligence (AI) are now available on the smart grid which incorporates the much-awaited touch screen human machine interface (HMI). Sophisticated protection system measurements are incorporated in the electrical installation to ensure its integrity and reliability. Differential protections and distance relays are major components in the electrical power system protection.
