Is there an approximate formula dealing with relationship between transformer price and its size? For example, assume two transformers of identical make, purpose, features, cooling and design, A rated 80 MVA while B is 120 MVA. Since the relationship between power output and qty of iron, copper, oil, etc, does not appear to be exactly linear (50% more power does not necessarily mean 50% more material) can one use an approximate formula to estimate budgetary cost of transformer B, if the price of transformer A is already known?
