Fault Analysis

A Fault Analysis is a study which describes the fault currents and the behaviour of a power system during an electric fault.  Faults may be line to line faults or line to ground faults. The fault analysis provides information about the  The Fault Analysis is used to determine the ratings of fuses and circuit breakers. 

Using the fault analysis, we can determine the maximum current which will be developed during a fault.  The bus bars, breakers and other transmission equipment should be equipped to withstand the heavy current which flow during a fault.

The protective relays are set based on the current calculated during the fault analysis.
