Sudden pressure relays (63AT and 63ST) provide sensitive protection against transformer internal faults. They respond to the sudden increase in oil or gas pressure that would occur as heat is generated during an internal fault. An auxiliary interposing relay is used with each sudden pressure relay to prevent false tripping of the main transformer.Get price
