Abstract
A winding temperature heater well for detecting the temperature of the oil about the coils in large transformers. The heater well comprising a temperature detecting device enveloped by a grid-patterned resistor element, the current through which varies directly with the current through the transformer, and a sleeve which protects the resistor and temperature detecting device from the oil. The heater well is embedded in a resin plate in such a manner as to allow calibration of the resistor from outside the plate.
