- Two 7970-V:230-V single-phase transformers with impedance with respect to their secondaries of 1.5 + j3 and 2 + j4.5 ohms are connected in parallel to a 7900-V source. Their secondaries are supplying a common load of 30 + j40 ohms. What is the magnitude of the voltage across the load in volts? (2 decimal places)Connect three single-phase transformers in Y-Y, with subtractive polarity, so that the line-to-line voltages on the primary are 30 degrees delayed to their respective line-to-line voltages on the secondary. It should show each step that is needed to make this connection (example: the phasor diagram) and should show the final connection of the three transformers including the polarity markings. Assume phase A on the primary is terminal "H1".Three single-phase transformers (ideal) are connected as shown in the figure below to supply a balanced 3-phase, 150 KVA, 600 VL load from primary 4.16 KVLL line.

- 5.In three-phase transformers, the high voltage star connection is preferred. This is so because in this case A) The voltage on the star windings is lower than if they were in delta and this reduces manufacturing costs. B) The voltage on the star windings is higher than if they were in delta and this reduces manufacturing costs. C) The voltage on the star windings would be the line-to-line voltage of the system since it is a three-phase manufacturing transformer. D) THERE IS NO SOLUTIONThree single-phase transformers, each rated 10MVA,66.4/12.5kV,60Hz, with an equivalent series reactance of 0.1 per unit divided equally between primary and secondary, are connected in a three-phase bank. The high-voltage windings are V-connected and their terminals are directly connected to a 115-kV three-phase bus. The secondary terminals are all shorted together. Find the currents entering the high-voltage terminals and leaving the low-voltage terminals if the low-voltage windings are (a) Y-connected and (b) - connected.Consider the three single-phase two-winding transformers shown in Figure 3.37. The high-voltage windings are connected in Y. (a) For the low-voltage side, connect the windings in , place the polarity marks, and label the terminals a, b, and c in accordance with the American standard. (b) Relabel the terminals a, b, and c such that VAN is 90 out of phase with Va for positive sequence.
