Iris Power Stator Slot CouplersTM (SSCs) are sensors specifically designed to detect stator winding partial discharge activity in operating gas or steam turbine generators.
Used in conjunction with the Iris Power TGA-S portable test instrument or the Iris Power GuardII continuous monitoring platform, the Iris Power SSCs are permanently installed under the line end stator winding wedges (in existing machines), or between the top and bottom bars (in new or rewound machines). The Iris Power SSCs are not connected tothe high voltage winding, and they are not subject to any high electrical stresses. Turbine generators rated up to 600 MVA normally require 6 SSCs, while higher rated turbine generators may require more.
