Abstract
A hydrogen cooled generator having a system for diagnosing problems associated with a seal oil system. Included is a shaft having a turbine end and a collector end; a first shaft seal located about the shaft at the turbine end; a second shaft seal located about the shaft at the collector end; a first set of sensors for measuring seal oil pressure differentials across both shaft seals; a second set of sensors for measuring seal oil temperature differentials across both shaft seals; a third sensor for measuring a hydrogen side seal oil flow rate; and a system for analyzing data collected from at least two sensors to diagnose the shaft seals.
