electricpete,
thanks for the note. i am trying to diagnose a problem with the transformer's cooling system.
i am not sure what the industry exactly means by the term "cooling efficiency" (it is used quite frequently - see Google) but I would expect (and what I am really looking for) is the...
Where can I find a method to calculate cooling efficiency for a oil filled transmission transformer? I have the top oil and ambient temperatures and fan/pump status.
Thanks
I am trying to calculate and plot apparent impedance from wavefom data captured by a substation relay. Where for Phase A the apparent impedance would be Va / (Ia + k*Ir). K would be a known value related to the zero and positive sequence line impedances.
A bit lost. Given that I have all phase...
