Ac Generator Theory Question #12
Question 12:
Suppose we have an alternator with two sets of windings, A and B:
Each pair of windings in each set is series-connected, so they act as just two separate windings:
If one end of each winding pair were connected together at a common ground point, and each winding pair output 70 volts RMS, how much voltage would be measured between the open winding pair ends?
Delta and Wye 3-Phase circuits Question # 15
Question 15:
One of the conductors connecting the secondary of a three-phase power distribution transformer to a large office building fails open. Upon inspection, the source of the failure is obvious: the wire overheated at a point of contact with a terminal block, until it physically separated from the terminal.
What is strange, though, is that the overheated wire is the neutral conductor, not any one of the "line" conductors. Based on this observation, what do you think caused the failure?
After repairing the wire, what would you do to verify the cause of the failure?
