A 440V, three-phase, delta-star system has load impedances of Zc = 34.2<39, Zb =34.5<55 and Za = 16.2<-45. A wattmeter is connected in the system with its current coil in line c and its voltage coil between lines c and a.
Take Ebc as reference with a positive phase sequence and calculate the reading on the wattmeter.
A second wattmeter is connected in line b to measure the total active power consumed by the the load. Calculate the readings on the wattmeters and prove Blondell's theorem.
