Duration: 4.5 days
Location: Warrendale, PA
Credits: 3.6 CEUs
Target audience
Power system engineers, field service engineers, application engineers, sales engineers, technicians and others who want a solid understanding of short circuit analysis.
Learning objective
At the completion of this course, students will be able to recognize the several forms of power system single-line diagrams, calculate short-circuit current, and evaluate the application of power circuit breakers and power fuses.
Abstract
Using classroom exercises and demonstrations, this training program reviews the fundamental techniques of power systems analysis. Although it is not intended to teach the use of power systems analysis software, the instructors will use laptop computers in the classroom and review examples to help explain the construction of system single-line diagrams and the calculation of short-circuit current.
Course topics include:
Introduction to power systems analysis: basic unit relationships (voltage/current/power); ANSI device/function numbers
Three-phase power fundamentals: power triangle, power factor, phasor diagrams; the per-unit system
Distribution equipment: transformers, induction machines, synchronous machines
Short-circuit analysis: sources of fault current, symmetrical short circuits, modeling a power system, making impedance diagrams
Unbalanced fault currents: derivation of non-symmetrical phasors from their symmetrical components, positive/negative/zero sequence networks, three-phase vs. single-line-to-ground and line-to-line faults
Data collection, short-circuit calculations, protective device ratings, device evaluations, main-tie-main closed-transition applications, capacitive switching
