Consider a power system given below in the Figure 1.There are three generators and their ratings are given as G1= 100MVA, 12.5 KV, 15% (reactance) G2= 70MVA, 12.5 KV, 20% (reactance) G3= 60MVA, 12.5 KV, 25% (reactance) A reactor rated at 6MVA with 5% reactance is connected as shown. If a 3-phase fault occurs near the G3, what is the total subtransient fault current? |
