Hmm Looks strange in Google. And there is no definition in English for creeping current while I found three for stray current. Is there an electrician on board?

stray current
leakage current in the Earth or in metallic structures buried in the ground and resulting from their intended or unintended earthing

I don't know what's the definition of "prąd pełzający"

Iwona Szymaniak May 12, 2011:

OK:), thanks but are they actually two different things or just two different name to name the same?

stray current to prąd błądzący http://www.electropedia.org/iev/iev.nsf/display?openform&iev...

And what about stray voltage or stray current? When I was in the US, I heard this term being used. I must add that the person who used it was not an electrician but a technician who installed milking parlors, and talked about risks associated with stray currents to people, animals and equipment. Are they two different things? Just wondering.
