"When it comes to transformer maintenance, there really is no such thing as a quick fix," commented Senja Leivo. "As transformer fleets continue to operate past their designed life span, online DGA monitoring is essential if internal faults are to be detected and addressed promptly and efficiently. It also provides an invaluable 'health check' following repairs and other service actions, demonstrating exactly how effective this work has been in targeting the root causes of gas build-up."
