Transformer health monitoring systems enable utilities to detect and diagnose transformer faults at an early stage, allowing for timely maintenance and repair. By implementing transformer health monitoring practices, utilities can improve the reliability and longevity of their transformers, reduce maintenance costs, and minimize the risk of catastrophic failures. Therefore, transformer health monitoring is a necessary practice for electric utilities to ensure a safe, efficient, and sustainable power supply.
