Short Circuit Analysis  
Short-circuit calculations are needed to check equipment condition in accordance with ANSI and NEC requirements. All equipment in the system including circuit breakers, panels, fuses, and switches will be checked for their interrupting rating to insure their safe operation and response in case of fault conditions.
 
Complete short circuit report will be generated including all equipment interrupting rating and recommendations will be made to correct any abnormal condition that is in violation of ANSI and NEC requirements.

Protective Device Coordination
All adjustable devices including protective relays and circuit breakers will be closely reviewed and settings will be examined to insure proper selectivity and coordination.
 
Recommendations will be made to implement different settings, if needed, to reach optimal selectivity that would isolate downstream faults and keep the system up and running.









Power Flow Analysis
The developed computer model will be used to analyze the existing power system conditions including voltage drop, motor stating and equipment overloading.
