摘要：

The most severe crash of a generator with a water-cooling stator winding is a phase-to-phase short circuit caused by hydraulic hermeticity failure and insulation wetting. The means of detecting insulation wetting in proper time and preventing a phase-to-phase short circuit are described. © 2009 Allerton Press, Inc.
