Power System Stability

The Sequence components of the fault current in a system are as follows:
= j1.5p.u
= -j 0.5 p.u
= -j 1 p.u
The type of fault in a power system is_____

Identify the location of fault in the power system shown in the figure below. A sustained 3-Φ fault occurred. (The voltage and current phasors, after the natural transients have died down are also shown.)
