Temperature monitoring system for an electric generator.

摘要

A generator having water cooled stator windings including a plurality of sensors each for measuring the temperature of cooling water prior to its entry in a manifold. Sensor outputs are combined for an initial average reading, each sensor reading is subtracted from the average to derive a correction factor. When operating, the correction factors are utilized to obtain a value for a percent of averaae coil temperature:where T is the temperature indication, AVG is the average, and CF is the correction factor.
