Resistance thermometer (RTD) with built-in heating element to simulate the measuring of winding temperatures within a transformer. Provides an analog (Pt100) output for remote indication and monitoring. Choice of one or two RTD’s allows for an extra signal for indication or input to SCADA system. Installed in a well (pocket) that allows exchanging units without draining the transformer tank.

 

For winding temperature simulation where the point of measurement (the well or pocket) is not easily viewed from the base of the apparatus or the information is required remotely.
