A conventional hydrogen-cooled electric generator having gland seals prevents the escape of hydrogen gas from the generator housing. A conventional seal oil system provides the gland seals with the necessary oil so as to perform their sealing function. Diagnostic apparatus is provided for the arrangement and includes a plurality of sensors which provide output signals indicative of certain parameters such as temperatures and pressures throughout the seal oil system. The output signals are provided to a diagnostic computer which, in a preferred embodiment, utilizes an expert system diagnostic routine for examining the sensor signals and deriving certain conclusions relative to the operating condition of the seal oil system. Various conclusions are additionally reached using operator-entered information from off-line sensors.

Diagnostic apparatus for an electric generator seal oil system

A connector assembly for joining gas-cooled phase leads of a dynamoelectric machine. First and second L-shaped plates connect each split end portion of a stator coil to a stator phase lead by means of screw bolts which join a shoulder portion of each plate with a crown portion of each plate. The opening defined by the interlocked crown and shoulder portions is adjustable to an exact fit with the conductor strands disposed therein by means of a slot in each shoulder portion which allows variable alignment with a tapped hole in the crown portion of each plate. After the screw bolts are tightened to a predetermined contact pressure, the conductor strands are soldered one to another and to the first and second connector plates.
