Real-time continuous monitoring: A new paradigm for transformer asset management

Traci Hopkins

Abstract

A major utility in the Caribbean discovered a fatal flaw in a transformer before it caused a costly incident. A hydrogen sensor recently installed on the transformer detected the presence of hydrogen gas in the insulating fluid. Crews were able to remove the transformer from service before a failure occurred. The article explains hydrogen sensor technology, discusses transformer reliability, and compares continuous monitoring to time-based maintenance.
