Assume a 275 kV transmission line having the following line constants:A = 0.85∠5° ; B = 200∠75° If a load is connected at receiving end at unity power factor but maintaining the same voltage profile. The receiving end voltage if the compensation equipment is not installed will be __________

Assume a 275 kV transmission line having the following line constants:A = 0.85∠5° ; B = 200∠75° If a load is connected at receiving end at unity power factor but maintaining the same voltage profile. The receiving end voltage if the compensation equipment is not installed will be __________ Correct Answer 245 kV

Pr = 150 MW, Qr = 0 |Vs| = 275 kV, |Vr| = ? 150 = (275*|Vr|)/200 cos⁡(75-δ)-0.8/200 cos⁡(75-5) 0=(275*|Vr|)/200 sin⁡(75-δ)-0.8/200 sin⁡(75-5) Solving the quadratic equations above and retaining the higher value for the voltage, |Vr| = 245 kV.

Seven people A, B, C, D, E, F and G live on separate floors of a 7-floor building. Ground floor is numbered 1, first floor is numbered. 2 and so on until the topmost floor is numbered 7. Each one of these having a different cars-Cadillac, Ambassador, Fiat, Maruti, Mercedes, Bedford and Fargo but not necessarily in the same order. Only three people live above the floor on which A lives. Only one person lives between A and the one having a car Cadillac. F lives immediately below the one having a car Bedford. The one having a car Bedford lives on an even-numbered floor. Only three people live between the ones having a car Cadillac and Maruti. E lives immediately above C. E is not having a car Maruti. Only two people live between B and the one having a car Fargo. The one having a car Fargo lives below the floor on which B lives. The one having a car Fiat does not live immediately above D or immediately below B. D does not live immediately above or immediately below A. G does not have a car Ambassador. Question : How many people live between the floors on which D and the one having a car Bedford ?
