ROTATING MACHINE, FAILURE DETECTING METHOD THEREFOR GENERATOR, ROTATING MACHINE, AND FAILURE DETECTING METHOD THEREFOR

Document Type and Number:

Japanese Patent JP3791339

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To detect leakage from a hydrogen gas system.
SOLUTION: A device of measuring the dissolved hydrogen concentration of cooling water is mounted inside the cooling piping system to monitor hydrogen gas leakage into a stator winding coil cooling piping system. By continuously measuring the dissolved hydrogen concentration of cooling water for a stator winding coil during running, hydrogen gas leakage into the stator winding coil cooling piping system is monitored from a change in the dissolved hydrogen concentration.
