Transformer winding thermometer USES the thermal simulation method

Transformer with a thermometer according to measurement purposes can be divided into: 1. Measure the top of transformer oil temperature 2. As the temperature of measuring winding winding thermometer 3. Measurement of winding thermoelectric temperature of winding thermometer 4. Measurement of dry type transformer temperature thermometer

hangzhou bimetallic thermometer manufacturer pressure instrument co. , LTD. Is hangzhou thermometer manufacturers, provide winding thermometer, bimetallic thermometer, etc. Winding thermometer as long as the working principle is to use the thermal simulation method. Abroad most of the substation adopts thermal simulation method to measure the transformer winding temperature profile, which is to use a flow of heating current in the electric heating element in the easy measurement of transformer top oil temperature T O basis, then applying a current transformer load additional delta T temperature changes, the sum of two T = T O + delta T can simulate the hot-spot temperature of transformer.
