Hydrogen Monitoring in the Transformer Headspace Compared to Traditional In-Oil Monitoring
By Chris Rutledge, Product Manager, Dynamic Ratings, Inc.
Introduction
The utilization of online dissolved gas analysis monitoring has proven to be one of the most effective predictors of overall transformer health and condition. A wide range of monitoring systems are available, offering multiple cost/feature/benefit combinations.
Hydrogen Monitoring
Single or key gas monitoring relies on the use of a sensor for the detection of hydrogen levels either dissolved in the oil or...
