Power Transformer Capacitance?
(OP)
Can anybody tell me what to expect for values of coupling capacitance between the windings and between the windings and core of power transformers. I'm particularly interested in 3 ph transformers rated at between 7 MVA and 100 MVA, with primary voltage of 72 kV L-L. Any help will be greatly appreciated. Thanks.

On high impedance grounding systems (and ungrounded systems) the capacitance of the transmission and sub-transmission lines as well as that of lightning arresters and transformers (of all types) the reference pathway is through capacitive coupling. It's this path that is of concern to me.
