摘要
A hot-spot temperature monitor for determining the hot-spot temperature of a transformer. The hot-spot temperature monitor determines the largest current flowing in the transformer and using this value calculates a temperature gradient. The temperature gradient represents the difference in temperature between the hot spot and the top-oil temperature. The top-oil temperature is also measured. The hot-spot temperature is calculated by adding the temperature gradient to the top- oil temperature. The hot-spot temperature sensor controls the transformer cooling units and can activate various alarms and indicators as desired.
