Generator Partial Discharge, Flux and End Turn Vibration Data Collection and Analysis Service

The agency is seeking data collection and analysis services for three GE 220600KVA hydrogen-cooled generators, model 7FH2-GTG. The project requires on-line air-gap magnetic flux measurements to detect shorted turns in the rotor winding using an existing flux probe installed in the stator wedge. The agency needs mathematical integration of the magnetic flux changes to provide numerical data proportional to the total flux. The agency also requires an assessment of the generator insulation system by comparing current partial discharge readings with historical measurements. Data must be gathered on-site at various generator loads, utilizing the existing BusTrac system on the STG asset and the GuardII system on the CTG assets without requiring additional portable testing instruments. Additionally, the agency needs end-turn vibration voltage readings collected at different load points from twelve VibroSystems FAO-100 vibration sensors mounted on each of the three generators. These sensors connect to a PCU-5000 instrumentation unit with BNC output panels, and the agency requires a condition assessment based on current and past readings. Eligibility is restricted to onshore, USA-only organizations. The agency requires all performance of the work to be conducted on-site. The agency is currently looking for proposals to establish the budget for this project, and no key dates are provided in the source.
