1 Sudden Pressure Protection for Transformers A report to the Substation Protection Subcommittee of the Power System Relaying Committee of the IEEE Power and Energy Society Prepared by the K6 Working Group December 2014 Assignment: To complete a technical report to the Substation Protection Subcommittee on the application of Sudden Pressure relaying in power Transformers . Members of the Working Group: Randy Crellin (Chair) Don Lukach (Vice Chair) Pat Carroll Mark Carpenter Arvind Chaudhary Steve Conrad Dominick Fontana Rafael Garcia
3.2 Flow Sensing The flow sensing sudden pressure relay is located between the transformer tank and an oil conservator and is commonly referred to as the Buchholz relay. This relay normally utilizes two different detection principles to detect transformer faults. One method is the accumulation of gasses within a detection chamber.
