Within our Electric Network we have several transformers within transclosures. The way they were explained to me is that it is an overhead transformer mounted to a short pole and inside a enclosure to protect it. These can be attached to underground single or three phase lines. There could be 1 or up to 4 in one location. Does the electric utility network have a way of modeling this now that I'm not seeing, or is this a situation that I should add a new asset type for MV transformers that is a Transclosure and rules stating that it can connect to a MV Underground Single or MV Underground Three Phase line?
