This paper introduces each type of environmental data includes entry ID, monitoring device ID, sensor ID, sensor status, collection time, and corresponding the environmental data values. The surface temperature in the figure shows the transient change from the 25.4° C to 42.6° C during the load change process, indicating the polarity reversal process will cause changes in the distribution of electric field strength on the valve side bushing, which will be characterized by the temperature changes. This is because the lower porcelain bushing is located in transformer oil tank, and the transformer oil temperature can be found to be 79.5° C from the experiments. The basic temperature is relatively high, and the main heat dissipation method is the oil flow caused by oil pump in transformer oil tank circulating to the radiator for heat dissipation. Taking the calculation model with a degree of freedom of 40 k as the example, the average calculation time of the model has been reduced from 3.2956 seconds for full order calculation to 0.02408 seconds for the reduced order calculation.
