Hi, So I was just vacuum cleaning the carpet in my room , I have wooden floor and the overall air is rather dry and warm.Normally I get static electricity buildup when vacuuming because the small dust particles that go through the cleaners pipe build up charge on the plastic pipe , I assume some charge settled on my skin and since i have wooden floor it stayed on me , then I switched off the vacuum cleaner and with my one hand wanted to move out of the way the power cord going into the cleaner , as I touched the cord it zapped me but not with the usual static kind of "zap" but with a bit more of something similar to an AC tingle which I am familiar with since i have been electrocuted from mains AC before. My question is is it possible that the high voltage static charge kind of broke down the insulation of the cable and he charge found its way into the neutral conductor back into the mains socket which was something like an earthing rod for the HV charge ? the cable is otherwise fine and has never caused any problems but this accident was strange. It's hard to say for sure because this shock wasn't like the ones I have gotten from bare wires but still it felt like a small vibration passing through my arm into my leg. what's the chance of that being a real shock or maybe my nerves simply giving me a false feeling of vibration which I have gotten a few times were electricity has been nowhere near. also if for example the insulation of the wire was indeed vulnerable and the static high voltage charge did pass through it how much of a current was there ? once more the fact that I was on a wooden dry floor , I assume the current there was extremely small but since the voltage was high it simply gave me a feeling yet after i checked my pulse and it was just a bit higher and that was probably from the shock feeling.
