“…Therefore, after running, the transformation ratio cannot be switched adaptively according to the running situation [7][8] . When the load of the distribution network increases or decreases, the current transformer load current is too large or too small [9][10] . However, if the current transformer ratio is too large or too small, it will affect the accuracy of electric energy measurement and the vital economic interests of both power suppliers and consumers, and will affect the performance of the current transformer itself.…”

“…Hence, the digital intelligence of the electronic current transformer (ECT) as a measuring equipment will be indispensable. In recent years, with the development of smart grids, ECTs have been used in large-scale pilot applications [4]. ECTs, as key measurement equipment for power grids, must be calibrated regularly to ensure the accuracy of their measurement performance.…”

“…Many monitoring and diagnostic technologies have been developed to address the problems in transformers. Online monitoring technologies can provide real-time information of the power equipment's state [3]. Nowadays, the key operation parameters of power transformers such as terminal voltage, current, ampere turns, and temperature are usually monitored continuously.…”
