[UC26] Transformer Loading Analysis

The Utility Problem

A transformer is a non-rotating electrical machine that enables the transfer of electrical energy from one circuit to another through electromagnetic induction. Each utility company has a significant number of transformers in their portfolio, forming a large portion of their overall assets. Utilities have developed a range of asset management techniques to manage this important portfolio. One of the more advanced techniques is Transformer Loading Analysis, which takes into consideration dynamic variables during operation.

Monitoring transformer loading over time is important for safety and system reliability. If a transformer is overloaded for a long period, it can shorten the transformer’s lifetime and cause failures, negatively affecting the utility’s reliability indicators. On the other hand, if the transformer is underutilized, it can be an inefficient use of investment funds and result in higher no-load losses.

Conducting regular Transformer Loading Analysis can bring multiple benefits in the form of improved decision-making in asset management and overall grid operations management. Overall, transformer is the key element in electricity distribution and managing them efficiently, helps maintain grid reliability, reducing energy losses and protecting the investment.
