Transformer Magnetizing Inrush 5

[Mbrooke]

Does anyone know how S&C derives transformer magnetizing inrush and hot/cold load inrush values? They seem to be on the extreme side, but then again they may have a point in terms of a feeder trip and reclose with residual magnetism in the core.

I quite agree that this is a problem.

Nothing has blown so far, but I just want to have this knowledge underneath my belt so to speak if it ever comes up in the future. My philosophy is prevention rather than attention after that fact.
