UST LPG distance to high voltage pillars

UST LPG distance to high voltage pillars

UST LPG distance to high voltage pillars

(OP)
Hi, couldn't find any references to minimal distance between under ground propane tank to pillar of high voltage. The pillar is grounded in case of a bridge of cables, and this creates a risk to close UST. Please advice, or give reference relevant. Is the electric distribution company has some rules about it? Regards E.L.

RE: UST LPG distance to high voltage pillars

I am not aware of any such regulation.
How far away is the pylon?

RE: UST LPG distance to high voltage pillars

Well it doesn't sound like a great idea, but you can't create rules for everything!

RE: UST LPG distance to high voltage pillars

Anything in NFPA?

RE: UST LPG distance to high voltage pillars

I don't see what the risk is though to a buried tank. Please explain.

RE: UST LPG distance to high voltage pillars

I ass-umed it was for a relief vent connected to the tank..

Is this question about cathodic protection interference ?

RE: UST LPG distance to high voltage pillars

(OP)
thanks to all responses. I'm just asking if someone have any references to such demand. I'v been informed, not officially by a friend that the authorities require a 20 meter distance between the earthing (or cathodic grounding) of the high voltage pylon and the UST, because of safety and not because interference with cathodic protection. THE RISK IS ELECTRIFYING THE TANK AND ITS METAL PIPEWORK IN CASE OF A BRIDGE OF HIGH VOLTAGE FROM cables TO THE GROUND. (HIGH VOLTAGE refers TO 1000 V AND MORE). Maybe, there is something in local regulations that you can help find. thx E.L.

RE: UST LPG distance to high voltage pillars

It looks like you need to ask "the authorities". Doesn't matter what anyone else says.

What "local regulations"? Where are you referring to as what one company says will have no impact on another.

If you do get a local grounding of a pylon from the cables then you can get a local increase in voltage. I don't know if this is enough to actually cause any issue in a buried tank or not and suspect its one of those things that just sounds like a good idea without any basis in fact or history of any issues

RE: UST LPG distance to high voltage pillars

Have you contacted the electrical service?

Einstein gave the same test to students every year. When asked why he would do something like that, "Because the answers had changed."
