Why 'during fault' do we use the transferred reactance of (X_12) 1.8 to calculate P2 Max. Why do we not include 0.54 or 0.8 (X_13 & X_23).

B) A 60-Hz generator is supplying 60% of P max to an infinite bus through a reactive network. A fault occurs which increases the reactance of the network between the generator internal voltage and the infinite bus by 400%. When the fault is cleared, the maximum power that can be delivered is 80% of the original maximum value. Determine the critical clearing angle for the condition described.

Q4) Consider three-stage space-division switch using CLOS criteria with N=450.4. What is the number of simultaneous connections if single-stage crossbar is to be used?

Briefly describe the trade-offs between ripple adders and adders with carry look-ahead.
