I got a call out tonight for a failed underground primary line serving a residential single phase service. In my area the property owner owns and is responsible for maintenance to the line. The POCO determined that there is a fault in the cable. How can I test/trace the cable to determine where the break is. I own the same underground locating equipment as dig safe if that will help? Thanks

You might get lucky if its open enough to the earth to make make contact with it and allow the use of a regular fault locator, but the design of the cable most likely will require a tdr/thumper.

I'll take on the burned secondary but not a primary. I wouldn't know where to get the materials to fix it, or how to splice it properly. There are plenty of private line companies here that I think I would farm that out to.

I agree with renting a thumper to find the fault. Honestly, since you're most likely gonna have to sub out the stress cones and whatnot anyway, I'd get in touch with a distribution contractor in your area and let them do the locates and repair.

Is this an industrial complex? Never heard of any resi. or commecial who owns their primary. But I definitely wanna see that thread on the DIY board:
"HELP PLS! Need 2 replace 15,000 voltage fuse!"
