S&C’s Power Systems Services Seminar:
Short-Circuit Analysis of Electrical Power Systems
The reliability and safety of electric power distribution systems depend on accurate and thorough knowledge of short-circuit fault currents that can be present, and on the ability of protective devices to satisfactorily interrupt these currents. Knowledge of the computational methods of power system analysis is essential to engineers responsible for planning, design, operation, and troubleshooting of distribution systems. Such knowledge is necessary to determine the interrupting requirements of circuit breakers and fuses, the mechanical and thermal requirements of devices exposed to fault currents, and to perform protection and coordination studies. Basic analysis concepts are also essential for developing equivalent system impedances used in voltage-drop, motor-starting, and harmonic analyses.
This one-and-a-half-day seminar provides attendees with an in-depth review of fault analysis problems in utility, industrial, and commercial power systems and provide the means for solving such problems, and discusses the impact of short-circuit fault currents on equipment selection. The course also highlights the differences in the computational approaches recommended in IEEE and IEC standards. A commercially available software program for performing fault analysis–PSAF-Fault–is used by the presenter to solve example problems.

- Fault analysis
- Interpreting and applying results
- Case studies illustrating critical issues
Credit for Professional Development Instruction
Upon completion of the seminar, participants will earn 1.2 CEU credits.
Instructors
Chris Brooks
Chris has over 25 years in the electrical power industry and has a rich background of experience in T&D management, engineering, research, planning, design, consulting, and training, both domestic and international. He also has experience in transformer design and manufacturing. Most of his career was with Westinghouse Electric Corporation and ABB performing and managing engineering and design projects for major US and international utilities and research organizations, but more recently he was the engineering manager for a rural electric cooperative utility followed by several years as the director of engineering of a consulting firm that targeted coop and municipal customers, At Westinghouse he was a participant and project manager for many major projects with Electric Power.
Jim Niemira
Senior engineer for Power Systems Services with 17 years technical and project management experience acting as project manager, project engineer, and lead engineer in varied areas of power delivery systems engineering including system analysis, equipment analysis, testing, product research, design, application engineering, substation controls, substation physical design, and technical instruction.
Mr. Niemira’s power systems analysis has included application engineering, transient analysis, fault current studies, coordination studies, ground grid analysis, seismic qualification of equipment, harmonic analysis, reliability analysis, failure modes and effects analysis, and equipment testing and certification including test program design to assure compliance with applicable industry standards and to meet other test objectives.
