Transformer Monitoring Guide

Power transformers are among the most critical and expensive assets on the grid, yet many organizations still rely on periodic inspections that only capture a snapshot of their condition. As renewable generation, changing load patterns, and aging infrastructure place new stresses on the grid, hidden electrical and thermal issues can develop between inspections and lead to costly failures. Online condition monitoring provides continuous visibility into transformer health, helping asset managers detect problems early, plan maintenance proactively, and operate assets with greater confidence, especially as transformer lead times now stretch 2–4 years and replacement costs continue to rise.
