Distance Protection of Electrical Power Systems Author: Velimir Lackovic Distance protection, is a non-unit protection arrangement providing significant financial and technical benefits. Unlike phase and neutral overcurrent protection arrangements, the key benefit of distance protection is that its short circuit current coverage of the protected element is almost autonomous of source impedance changes. Since the... Learn More
Power System Transient Stability Study Fundamentals Author: Velimir Lackovic The ability of a power system, containing two or more synchronous machines, to continue to operate after a change occurs on the system is a measure of its stability. The stability problem takes two forms: steady-state and transient. Steady-state stability may be defined as the ability... Learn More
Power System Short Circuit Current Studies Author: Velimir Lackovic Short-circuit studies are done to determine the magnitude of the prospective currents flowing throughout the power system at various time intervals after a fault occurs. The magnitude of the currents flowing through the power system after a fault varies with time until they reach a steady-state... Learn More
Cathodic Protection This course presents standard methods and best practices related to designing and constructing cathodic protection systems. It provides a detailed analysis of corrosion and various types of cathodic protection currently in use. Students will learn how to develop a design basis for cathodic protection systems, design techniques, and data requirements for a full-scale... Learn More
NEC Area Classification A major safety concern in industrial plants is the occurrence of fires and explosions. No other aspect of industrial safety receives more attention in the form of codes, standards, technical papers, and engineering design. Regulatory bodies like the Occupational Safety and Health Administration (OSHA) have established systems that classify locations which exhibit... Learn More
