Abstract
In accordance with the present invention, there is provided a hybrid mechanical and electrical transformer temperature monitor. The mechanical sensing mechanism drives mechanical switches, a local display and a sensing input to the electrical side of the monitor. The electrical portion of the temperature monitor has the ability to calculate winding temperature (with an additional current sensor), data log, actuate electrical switches and has a local display for winding temperature.
