He commenced his career working on the Hot Strip Mill in a steel plant, on maintenance of protection systems and Variable Speed Drives, for 10 years. He then spent 9 years in the oil and gas industry where he was involved in the commissioning and maintenance of the complete spectrum of Power Electronic and Power Engineering equipment. He has devoted the next fourteen years to a combination of research/consulting and lecturing, focusing on Power Distribution, Power Systems Protection and High Voltage Engineering. One of his major successes during that period has been the designing, equipping and commissioning of a complete high voltage laboratory for the engineering school of a prominent University of Technology. He is still involved on a part-time basis as a consulting professor in the Institute for High Voltage Studies. He is also a director of a consulting company focusing on high voltage testing and the supply of test equipment. Jerry is a particularly entertaining instructor with a host of experiences in, and a tremendous passion for the topic of Electrical Power Cables and Insulation Systems.JERRY waLKER (D.Tech)The WorkshopThe continuity of the electrical power supply is very important to consumers especially in the industrial sector. Protection relays are used in power systems to maximise continuity of supply and are found in both small and large power systems from generation, through transmission, distribution and utilisation of the power. A good understanding of their application, operation and maintenance is critical for operating and maintenance personnel. In this course, you will gain a thorough understanding of the capabilities of power system protection relays and how they fit into the overall distribution network. The practical sessions covering the calculation of fault currents, selection of appropriate relays and relay coordination as well as hands-on practice in configuring and setting of some of the commonly used types of protection relays used in industry will give you an excellent understanding. Simulation software and real relays (but at safe voltages) will be used to give the course participants practical experience in setting up and configuring the various power parameters. Both electro-mechanical and microprocessor relays will be used to demonstrate the key configuration settings required and the major differences in the approach adopted between these two classes of relays.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 themselves 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. There will be at least nine practical sessions interspersed within the different theory sessions. These will enable participants to gain a practical feel of actual power systems and their protection system designs, plus substation automation and wide area protection architecture.
