A Design Method for Enhancing Distribution Transformer Overload Capacity

Abstract

For problems such as low rural power distribution transformer overall utilization rate, the short-time serious overload and low power supply reliability, the paper put forward a design method for enhancing distribution transformer overload capacity to solve the problem of distribution transformer overload, including material selection, temperature rise calculation and test scheme. The research direction of high overload capacity distribution transformer and problems that should be paid attention to in the application are presented with the test results.

Research on transformer load forecasting based on deep learning

“…Typically, a transformer is considered overloaded when its load reaches 80% to 100% of its rated capacity, and overload state is defined when the load exceeds the rated capacity, i.e., operating beyond its normal load value [2] . In general, transformers are not allowed to operate in an overloaded state for an extended period, as this can lead to a shortened lifespan and may result in various faults or accidents [3] [4] .…”
