Generator Step-Up (GSU)
Transmission-class step-up
Overview
Step-up interface between generator and grid. Robust thermal design for cyclic and continuous loading. Use our datasheet templates and outline drawings as starting points. Final specifications are established by contract.
Typical ratings & options
- Voltage: Low-voltage generator side, HV grid connection
- MVA: Matched to generator capacity
- Cooling: ONAN, ONAF, OFAF options
- Thermal design: Cyclic and continuous loading capability
Referenced standards
IEEE/ANSI/IEC applicable standards as specified. We do not claim certifications.
Test program (described)
Factory testing subject to contract and witness arrangements. May include impulse, partial discharge, heat-run testing, and routine tests per specification.
Accessories & monitoring
DGA, PD, and fiber-optic temperature monitoring available by specification.
