    AutoTransformer Question

    It means actual winding power handling capacity is only 1015 KVA but this autotransformer can handle 5000 KVA means auto transformer can handle 5 times more power and 5 times smaller than a conventional 2 winding transformer

    Electromangetic Filed fluction

    An electromagnet can be used for moving scrap steel from one place to another. In a scrapyard, a crane has a large iron disc that is not a permanent magnet. The crane operator lowers the electromagnet into a pile of scrap steel and then switches on the electricity.

    Generator internal voltage

    ye the answer should be :Vi = Vt + Id*Xd = 1+ 0.97*1.1j = 1.46 pu So, the voltage is 1.46 * 250 kV = 365.6 kV there can be mistake in solution manual.

    Problem 530 (NCEES)

    we can use MVA Method, 40MVA in series with 25 MVA (1MVA/.04) and 40 X 25 / (40+25) = 15.38 MVA we find out that Fault is on the 480v bus 15.38MVA/(sqrt(3) * 480e-6MV) = 18,500A

    home made electrical components

    To create a wirewound resistor, one piece of wire would have to serve as the path for the electrical current to flow from one end of the resistor to the other. To create a resistor with a small resistance (or Ohm) value, use a thicker, shorter wire as the path between the two electrical leads.
