Stator Slot Couplers
Typically used for large turbo generators (larger than 100 MW), Stator Slot Couplers (SSCs) monitor partial discharge activity occurring within the stator slot and at the endwinding region of the generator windings while eliminating all types of electrical noise. The standard package includes 6 SSC's per generator, a termination box, coaxial cables, and a hydrogen penetration (if required). Machines rated above 800 MVA may require more than 6 SSC's depending on the number parallels per phase. An external power frequency reference is required. A typical installation takes 4 days
