PowerWorid Simulator case Problem 3_60 duplicates Example 3.13 except that a resistance term of 0.06 per unit has been added to the transformer and 0.05 per unit to the transmission line. Since the system is no longer lossless, a field showing the real power losses has also been added to the oneline. With the LTC tap fixed at 1.05, plot the real power losses as the phase shift angle is varied from 10 to +10 degrees. What value of phase shift minimizes the system losses?

A three phase, 33 KV, underground cable system, consider a single core of conductor radius 0.8 cm diameter and lead sheath of 2.3 cm. The core and lead sheath have been separated by two intersheaths with radius 1.3 cm and 1.8 cm. Draw the cable core, dielectric and intersheath layers showing the thickness of each layer, then determine the voltages on the both intersheaths. Suppose the maximum stress on the layers are the same. Please i need it know please
