@tubetime Generators often do the same with stator windings: they are basically pipes and distilled water is passed through them. I'm not entirely sure why conductivity of that water matters (after all its share of current will be very small, and it being AC would seem to obviate worries about corrosion). It seems that here the internal pipe is insulated?
@robryk @tubetime those distilled water systems are an absolute trip, when the water is pure enough to have very high dielectric strength it starts trying to yoink metals and even plastics into solution to scratch its polar itch.

@vxo @robryk @tubetime yep, see e.g.: https://techhub.social/@stereo4x4/111353086754094534
@stereo4x4 @robryk @tubetime I suspect that water was not only very pure but also acidic. Evil.

Ah, it's at least partially about leaks, which might create a water path between stator winding and ground. See e.g. https://www.nrc.gov/docs/ML0306/ML030650924.pdf
