要約(英語): It is desirable to operate power equipment such as transformers considering improvement of utilization rate and the lifetime. It is considered that the application of dynamic rating to improve the utilization rate. However, the equipment is increasingly used with high load due to the dynamic rating, so it is necessary to understand the lifetime of the equipment and operate it. In order to implement the current capacity calculation formula and the average degree of polymerization calculation formula using for transformer lifetime estimation, it is required dedicated devices to perform complicated calculations for each formula. Therefore, this paper considers creating formulas with only four arithmetic operations for the current capacity calculation formula and the average degree of polymerization calculation formula, and implementing them in the same device. Also, it is required overload protection relay to perform dynamic rating, in order to prevent equipment failure. So, this paper shows the implementation of three functions, dynamic rating, overload protection function, and the average degree of polymerization calculation formula, for one IED that can perform simple calculations.
