winding ct is provided on the LV side of the Power Transformer. This winding ct is connected to the winding temperature indicator with a resistor at WTI end.This resistor produce heat proportional to the circulating current due to heat produced in the winding. WTI dipped in the oil of the power transformer which measures the heat produced in the oil. WINDING TEMPERATURE = HEAT PRODUCED IN THE OIL + HEAT PRODUCED IN THE RESISTOR DUE TO WINDING CT. Usually for power transformer winding temperature Alarm set at 85 degree celsius and trip at 90 degree celsius.
