Unformatted text preview: 230 volts across the load. What is the voltage at the high voltage terminals? Compare the results using the Tequivalent circuit and an approximate equivalent circuit. c) What is the transformer efficiency under the load conditions in part (b)? 1 of 2 100/0 Vj2 Ω j ϖ M = j2 Ω j4 Ω +2 Ω 2 Ω 4 Ω j3 Ω 3. A singlephase load is supplied through a 33000 V feeder whose impedance is105 + j360 ohms and a 33000/2400 V transformer whose equivalent impedance is 0.26 + j1.08 ohms referred to its lowvoltage side. The load is 180 kW at 0.8 lagging power factor and 2200 V. Calculate the voltages at the sending end of the feeder and at the primary terminals of the transformer. Compute the real and reactive power at the sending end of the feeder. 2 of 2 33000/2400V Transformer 33000V Feeder Load...
