TV Cable

[Erincka]

Hello, I wanted to move the tv from the kitchen, and the tv cable hit the fridge which cut the power, could someone tell me how to test the current coming out with a multimeter? I tried in AC and I have about 3volt but I am not sure, thanks in advance

Measuring between the shield of the T.V. cable and the refrigerator 3vac is a bit high but I have seen worse on 'grounded' equipment. Did you make the measurement after restoring the power?? Wonder if there was a 'hot' exposed connection behind the refrigerator?? With the fridge properly grounded there should not have been an issue since the shield of the cable should also be at ground reference.

No, I just did the tests before posting the message, when the plug was pulled out she knocked against the iron in the fridge and it cut the power, and there I tried removing the antenna from the TV and with the multimeter, put the + in the pin inside, and the - outside in AC mode

You won't measure anything of value that way. In fact the post doesn't make sense at all. Maybe measure between the cable shield and body of the refrigerator. Is it possible there is a short in the fridge making the cabinet 'live'?? If so you have a real shocker of a problem. Power of course must be back on.

I thought there was electricity in the antenna cable because I put a signal amplifier in a box that's why I did that, on another TV's I have 0.070 is that normal?
I will try to test the outlet where the fridge is plugged in

I followed this guide : https://www.techwalla.com/articles/how-to-test-for-voltage-on-a-coaxial-cable

What exactly do you mean by "cut the power"? Like a mains circuit breaker tripped?

I do not know how to say in English, the Electrical Counter has disjointed at the time when the antenna has typed on the fridge

Sounds like what has likely happened is there is a fault in either the refrigerator or the outlet it is plugged into, the typically earthed coax braid made contact and tripped the RCD protecting the fridge's circuit. That or the coax is no earthed and your signal amplifier or it's power supply has a similar mains fault and it grounded out on the fridge, again causing a RCD trip.

Either way something is likely presenting a serious shock hazard, proceed with caution.

Pictures are always helpful.

Thank you for your advice I will try to test the outlet where the fridge is plugged in, so it is possible that there is current in the coaxial cable, so normal the way I tested?
