Testing........

[Alwayslearningelec]

We have cables coming into manhole...600V DC. Is there something that's inexpensive that can be used to test for leaky/stray voltage? Some conduits have 4 cables. Thanks.

Under $700.

A megger test?? I'm talking something that you could just wrap around the cables or do right at that location... Or clamp around the cables For a megget don't you have to be a both ends of the cable? We want to do this while the cables are live.

Where exactly are you wanting to test for this voltage? From what point to what point do you think you have "stray" voltage. What is the reason for doing this testing?

We have to fill the conduit with a duct seal type of sealer. It's applied with caulk gun and tube of the sealer. Before we do this we want to check for any stray/leaky voltage. We may do it live.

It sounds like you need to test for leakage current, not voltage.

Turn the power off. Disconnect the wires. Meg it. My Fluke was 400+-.

Yes sorry

That was not carried in our bid...no way we can do that ...we d be royally screwed . We qualified shutdowns were not included so we may have an out. Btw does megger test for current ?

 

[ptonsparky]

You’re screwed.

Ok, hopefully someone can help with suggestions to mitigate the damage.

Would you apply this to a conduit with live 600v cables?

Voltage leakage will be apparent from testing in 2 locations...anyway-
A private megger guy isnt that much...

What documentation exactly is the customer/contract asking for

What documentation exactly is the customer/contract asking for

None at all. Just a safety think . One of the guys said he'll put the sealant in live and another wont ...we want to at least mUbe test so there no start current or voltage but something that will take minimal time to do

As I recall the OSHA rules for being in a manhole with energized conductors requires Level 4 arc flash protection, even where the conductors are insulated.

Not sure that there is any test that will accomplish what you want. Maybe a voltage probe with one end against the conductor and the other in the earth outside of the manhole, but it would have to be a low resistance meter, as the high resistance digital meter will very likely show voltage.
