Today’s dynamic electricity market places real pressure on critical assets across the rapidly evolving grid, with transformers playing a vital role in the safe, reliable, transmission and distribution of electricity. This places new demands on transformer operators to understand and mitigate the impacts on performance, safety and operational life. Real-time monitoring and diagnostics are recognized as a key requirement in addressing these demands and moving toward a predictive maintenance model – enabling the prioritization and effective targeting of limited maintenance, repair and replacement resources.
