Installing, Programming & Commissioning of Power System Protection Relays
Introduction:
The continuity of the electrical power supply is very important to consumers especially in the industrial sector. Protection relays are used in power systems to maximize continuity of supply and are found in both small and large power systems from generation, through transmission, distribution and utilization of the power. A good understanding of their application, operation and maintenance is critical for operating and maintenance personnel.
In this course, you will cover a thorough understanding of the capabilities of power system protection relays and how they fit into the overall distribution network. It will also cover the calculation of fault currents, selection of appropriate relays and relay coordination as well as configuring and setting of some of the commonly used types of protection relays used in industry. The strengths and weaknesses of the latest microprocessor (or numerical) relays as compared to the older electromechanical relays will be outlined. You will also gain a solid appreciation of how the modern relay communicates not only to the central SCADA system but also between them resulting in a truly multifunctional system which includes protection, control and monitoring. Finally, you will gain a solid understanding of issues of reliability and security for the modern relay.
