Guyz will you please help me out, im not good when it come to electronics design. Im building a high and low voltage protector for home appliance, the circuit that im building is on this site **broken link removed** but the part that i dont understand is the first part which are two transformers (X1 and X2). Im not sure whether these are auto-transformers because their secondary ranges 0-24v and for X2 0-12v,is it one type of transformer or what?
If Nigel has the correct link the circuit will not detect under/over voltage but only a phase loss in a 3 phase Y (WYE) configuration. Additionally that website has a rep for several circuits that do not work at all as well as poorly designed circuits.

Beats me Nigel, at least you placed time and effort into trying to find the correct circuit. Maybe when and if the OP returns he can provide the circuit he had in mind. Till then.... Oh well.
