another urd thread

what is the amount of stand/offs or parking stands that you might carry on a truck during a shift?I guess it would depend on what shift and the amount of urd in your area.........on a 12 midnight -8 am shift we would carry about 6 or 8 for each 12kv and 34.5........sometimes using them all and re-stocking the next day.and no,I didnt forget the dummy plugs.

Ummmmmmm space on a truck was limited so I carried 6 for 13 and 6 for 34.5. That in itself took up a lotta room.Ummmmm I also carried a handfull of fuses for the urd bayonets. Never had to use many kause it was rare they would blow.

Dang Poot ,I didnt expect anyone to have as much as we carried,what shift was that? Your right that they take up alot of room and if you use that much on any shift,then thats what you would call a busy one.We were a 2 man crew that had 4 or 5 areas,so there wasnt anyone to call if you ran out..........and what city was you in,carrying that amount of stand/offs...........now as far as fuses go,have you ever refused a livefront transformer,its not done too often and my experiences werent that great,Id guess Ive seen one that held,I can barely remember what they looked like but they were located behind the u-clamp where you bolted the primary lugs on.

Ummmmmmm I was By myself and often 25 miles or more from our shop. Evenings and midnights a fella was on his own.And I yes I bleve I have refused a live front. Seems like they had a sand fuse that you had to take out to reset it then fish it back in and close it. We had a couple of folks get hurt on livefronts so they became outlawed and when we ran across one it got changed shortly thereafter.

It was a screw in type of fuse,and now looking back it was meant to refuse when the loop was de-energized,that may be the reason most of ours didnt hold,but one did hold..........dont get me wrong ,it wasnt done often.Usually if there was no voltage on the secondary side,we just called it a bad pot.

Ummmmmmmm Our livefronts had 3 switches in em ,one for the incoming primary, One for the outgoing Primary, and the one for the transformer was between them.I dont think we ever had a 3 phase livefrront. When opened the fuses( switches) had a springloaded trip device and a plastic shroud popped over the metal contact on the switch . the entire switch blade had to be taken out with a stick to reset that plastic shroud thingy

I believe what you are talking about is an arc strangler. We had quite a few, both single phase & 3 phase & the nice thing about them is they could drop load or break parallel.

Kind of off the topic,but since we are dicussing urd,Ill use this opportunity to tell a small story and ask if any one if you have heard this,I knew a fellow lineman,you could call him an oldtimer,he once told me that you could locate bad urd drops by using a battery opperated radio,the catch was that the radio had to be on the am frequency,and you would get more static when you ran the radio over the bad area of the urd drops.....Ive never had much luck with it ,but then again I didnt experiment with it too much,and id guess it would work better if the ground was a little wet.Anyone ever heard of that one?

Before all the sophisticated equipment of today or at least before we got any of it, we use to use an radio dialed in to an AM station to find interferrence problems, but that was a long time ago.
