Advice On Sensor Positions

cheers my apc smart ups' have been clicking over into over voltage protection lately, IIRC the logs showed 260vac+ which is nice... Seems to happen every time we get powercuts. Will have a good ol' Google.

:P

If you can prove the 260, then your electricity supplier will be forced to resolve that..... However i doubt the readings accuracy. I imagine lots of things going bang at a peak like that

Tested this morning with my multimeter and was getting 246, I'll test it again when the ups clicks over to AVR trim.

I've planned my cable runs so not to go anywhere near mains wiring.

This is where the ac filters would go? Providing I had over 1.2vac being measured.

One of the filters is a mains filter, you wire from the spur to the filter and use the filtered output in your mains connections.

The 1313 is a low voltage spike suppressor this has three wires a 12 positive, a 0V negative and a mains earth. You only require one of each filter.

FYI the filters come with destructions.

thanks, I'll defiantly be getting a 1313 then, just as a precaution.

Most don't need one.

Someone told me I was ignorant and apathetic, I don't know what that means, nor do I care.

True, most sites with metal end stations and cables away from mains don't.

It was mentioned how to test if you need one above. Ox's Post.

Test between a 12Vdc connection and mains earth on your lowest AC range; if over 1.2Vac fit one.

Sometimes putting your spare cores to earth can do the same thing, depends on the installation.
