Whenever a fault occurs in
an electrical power system, relatively high currents flow, producing
large amounts of destructive energy in the forms of heat and
magnetic forces. A short-circuit study ensures that protective
device ratings within a power system are adequate for maximum
currents that flow during a fault.
Energy and Automation
can perform a short-circuit study to:
- Make certain
protective devices have adequate interrupting current capability;
- Ensure power system
components can withstand mechanical and thermal stresses that
occur during a fault; and
- Calculate current
data for protective device coordination studies.
Computer-based modeling is
used to calculate maximum three-phase short-circuit currents which
are compared to protective device component short-circuit currents'
ratings. |
