Textbook Question
Chapter 3.3, Problem 2T
The two primary windings of a dual-primary control transformer (240 V or 480 V) are to be connected in parallel to step the line voltage of 240 V down to a control voltage of 120 V. Assuming the two primary windings are incorrectly connected in series instead of parallel what effect would this have on the control circuit?

- 5.1 Determine the three zone settings for the relay Rab in the system shown in Figure 5.26. The system nominal voltage is 138 kV, and the positive sequence impedances for the various elements are given in the figure. The transformer impedance is given in ohms as viewed from the 138 kV side. Assume that the maximum load at the relay site is 120 MVA, and select a CT ratio accordingly. The available distance relay has zone 1 and zone 2 settings from 0.2 to 10 2, and zone 3 settings from 0.5 to 40 2, in increments of 0.1 2. The angle of maximum torque can be adjusted to 75° or 80°. Remember that the zone 3 of the relay must back up the line BC, as well as the transformer.
