Consider a transmission line of characteristic impedance 50 ohm. Let it be terminated at one end by +j50 ohm. The VSWR produced by it in the transmission line will be
View Answer Explanation
A 2-wire ring distributor is 300m long and fed at 240V at ‘A’. At ‘B’, 150m away from A, a load of 120A is taken and at ‘C’, 100m away in opposite direction a load of 80A is taken. If the resistance per 100m of single conductor is 0.03?, then current in section AB feeder is ___________
A transmission line whose characteristic impedance is a pure resistance
A transmission line of pure resistance characteristic impedance is terminated with an unknown load. The measured value of VSWR on the line is 2 and a voltage minimum point is found to be at the load. The load impedance is then
For a given system consisting of two generators Units Rating(MW) Speed Drop(%R) 1. 400 0.04 2. 800 0.05 The units share load of P1=200MW and P2=600MW. The units are operating in parallel to share a load of 700 MW at 50 HZ. The load is increased by 130MW with B=0. Then the value new steady state frequency variation is ______________
