Positive Negative Zero Sequence Impedance  Under Electrical
Protection  Before applying proper electrical protection system,
it is necessary to have through knowledge of the conditions of
electrical power system during faults. The knowledge of
electrical fault condition is required to deploy proper
different protective relays in different locations of electrical
power system. Information regarding values of maximum and
minimum fault currents, voltages under those faults in magnitude
and phase relation with respect to the currents at different
parts of power system, to be gathered for proper application of
protection relay system in those different parts of the
electrical power system. Collecting the information from
different parameters of the system is generally known as
electrical fault calculation .  Fault calculation broadly means
calculation of fault current in any electrical power system.
There are mainly three steps for calculating faults in
