Seminar

Everything you wanted to know about fault studies, but were afraid to ask. This seminar will teach how to perform manual and computer calculations to determine fundamental frequency voltages and currents during short circuits on electric power systems. Topics covered include:

• Impact of short circuits on power systems. Relevant factors with respect to power system stability, reliability, power quality and protective relaying.
• Use of per unit systems and comparison with physical units.
• Short circuit levels in MVA or kA.
• Fundamentals of symmetrical components and their application in analysis of short circuits.
• Sources of data for short circuit calculations.
• Manual calculations of short circuit currents and voltages.
• Impact of rotating machines on short circuit calculations.
• Overview of applications of short circuit studies such as protective relaying calculations, circuit breaker ratings, voltage sag studies, and ground grid design. Detailed discussion of applications is not included due to the large variety of applications and extensive content of each application.
• Uses and abuses of fault studies.

The short circuit computer program ASPEN OneLiner will be used as an example of a computer tool for short circuit analysis. However this is not a training seminar on the use of ASPEN OneLiner.

** Note: Please bring a calculator to the session.
