In fact, water, especially distilled water resulting from "rain", is a very poor conductor. The elt runs at low voltages as well and the chance of any serious current flowing from condensate are negligable.
If you have a Fluke or similar multimeter, try measuring the resistance of a glass of boiled water from the kettle, say with the probes at a cm spacing, to get an idea.
Again, all this smells of misinformation, un-named sources being given publicity which is then spouted by the media as possible cause, may be just a smoke screen to hide the real problem.
