The utility model relates to an electric power system field provides a transformer winding deformation monitoring facilities very much, including data processing module, with voltage acquisition module that data processing module connects, the 2nd voltage acquisition module, first electric current collection module, second electric current collection module and with the host computer that data processing module connects, data processing module is used for calculating the transformer short circuit reactance according to the voltage of gathering, current data, the host computer is used for the basis the transformer winding deformation early -warning singal is sent in the short circuit reactance. This transformer winding deformation monitoring facilities realizes the unmanned on duty on -linemonitoring to transformer winding deformation through collection module, data processing module and the host computer of separately installation. Do not need the transformer to have a power failure in the time of the on -the
