8262.5 ▸ A balanced star connected load is connected to a 4 kVA, 415 V, star connected three phase generator via a three wire transmission line. The impedance of each line is 0.3 + j6.0 ohms. The synchronous impedance of the generator is 0.4 + j2.4 ohms. The fixed losses of the generator are 175 W. The field winding is connected to a 120 V source and the field current is 5.5 A. When the generator delivers rated load at rated voltage and at 0.866 power factor lagging, find ▸ The efficiency of the generator (79.8%) The voltage regulation at the load (11.2%) ▸ The efficiency of the entire system. (79.2%) Ts = 8262.5w (401) =65.74 N.m ▸ Draw the power flow diagram of the entire power system indicating on the diagram all the values of the power flows.
