Short Circuit Calculations & Studies
Short circuit calculations and studies are based on 5
primary aspects.
1. Avoiding any catastrophic losses and reducing any
potential electrical risk to a facility.
2. Increase both safety and reliability of an electrical
power distribution system and equipment.
3. Evaluating protective devices, equipment and
applications associated with electric power.
4. Identify any problems and faulty areas in the
system.
5. Obtain OSHA and other electrical safety code
recommended solutions.
Working on larger electrical systems in commercial
facilities requires studies to determine switchgear
ratings and relay settings. Short circuit studies are
considered very useful as it is one of the most serious
threats to human life due to extensive equipment
damage caused by fault currents.
