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 air gap. The selected contractor must evaluate the change in magnetic flux through mathematical integration to provide numerical data proportional to the total flux. The agency also requires partial discharge assessments to determine the overall condition of the insulation system by comparing recent readings with historical measurements. Data collection must occur 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 project covers end-turn vibration assessments using the twelve existing VibroSystems FAO-100 vibration sensors mounted on each of the three generators and connected to a PCU-5000 instrumentation unit. The agency requires voltage readings at different load points to compare current and past readings for a comprehensive condition assessment. Bidders must be onshore USA organizations to be eligible for this opportunity. The agency requires all performance of the work to take place on-site. The agency is currently looking for proposals to establish the budget, and the source document does not specify further evaluation criteria or key dates.
