    This demonstrated a bit more planning and control than the usual method of spiking an unknown cable, involving a digger bucket and an operator in need of a new pair of trousers.

      We sold some land for a small development, I noticed the digger driver in large ish (13 ton) machine going very deep and fast in the location of a previous twin pole and transformer location, that was removed and put underground maybe 15 to 20 years earlier....I walked up the field and warned him, he basically blew me off! "Weston power have checked it!" He pointed 👉 further up the field it's up there!!! I went back indoors, 3 minutes later, an almighty bang and flash, I ran back out to see if he was alright, his face was a picture LOL 😆. I couldn't help but say "You found it" 11kv and knocked out power to about 1000 homes for hours.

    Some years ago (early 80's) I was working for a large, well known UK company who were carrying out major expansion work on one of their sites. The contractors had unearthed a large "cable" that needed to be dealt with before they could move forward with their groundwork.
    Unfortunately we had a senior engineering manager who was a totally incompetent idiot whose first reaction was to send a message to the electrical department to send a couple of sparkys with hacksaws to cut out this piece of redundant junk that does not show up on any drawings.
    When we all refused point blank to do this he came back with, "OK we'll spike it, and then there will be an enquiry into why you are all refusing to do what you are paid for".
    So the following day we all turned up to watch this cable being spiked, because after all it is not something that you see every day and we were all horrified to see this tw*t turn up with our newest apprentice who was wearing a visor, rubber apron, heavy rubber gloves and carrying a sharpened bastard file and a lump hammer.
    Despite all our (very vociferous) objections this poor lad was bullied into standing in the trench, file pressed against the cable's casing and lump hammer raised while I was praying that in the worst case scenario, a cable that size must be an oil filled HV cable that will trip on the slightest loss of oil pressure.
    The lad's name was Terry and he was absolutely terrified when he closed his eyes and swung the hammer....
    We all stared in amazement when instead of a loud bang, a jet of water shot about 60 feet into the air and started rapidly filling the trench with water.
    In the aftermath of all this, Yorkshire water were massively unimpressed that no one had asked them if this was their water main and we did get a new senior engineering manager

      @@kss987 Modern ducts and pipes tend to be color coded as do some cables. IIRC it's Black for LV (under 1KV, normally 230V/400V) electric, Red for HV electric, Yellow for gas, Grey for BT, Green for cable TV, Orange for traffic lights and Purple for motorway services. Fiber altnets seem to often use orange or purple too.
      Direct buried comms cables and older plastic water pipes are often black though and there is certainly size overlap between the three categories. So they could easilly be mistaken.
      Cables that pre-date modern plastic would often have a metal armour coated in fabric and tar. Again this could look pretty similar to a pipe coated in the same way.

    The Dead short is how you identify a decommissioned cables as shorting cap ends (copper braid and nails into all cores and neutral earth's) are applied to either side of the disconnect, so if found and opened under live working techniques' it can be identified as a decommissioned cable. It's done on both sides of the disconnection so at any point if opening and cutting it can still be identified, if your leaving it the ground you should re-applied a shorting kit to each cut end so future jointers can also identify it without the need for using a spike (which we only spike HV, use live techniques on all of cables and testing). Ps I work for a DNO as a LV/HV cable jointer.

      They’re not dno cables though, they’re swa cables so by rights can’t be opened to test as they’re not designed to be worked on live. I’ve spiked many dno ooc LV’s over the years. I worked on a massive city centre project that involved spiking 100’s if not 1000’s of pilcs that where not on the drawings and needed rid of. The only thing to do was spike every 1 and hope for the best

    Many years ago we did an inventory of all the supply lines on a major site (dozens of buildings) on a chemical development site. All went went well upon one out going group, measuring around a 90 amps three face live…. All efforts (tracing, following etc) to locate the end of that supply failed, so out of a safety point of view the decision was made to switch off the one supply and find out where it was going. A plan was made about a hundred people in on a Saturday morning and….. damn … a hidden supply to a major computer server room. In the room unbelievable a wall was setup in front of the distribution board! What idiot did this .. we never found out.

Telecoms equipment down equating to £300K loss of revenue for twelve hours. My mate Darren attended site as a P1 ( priority 1 call out ) spent several hours trying to find origin of EE electrical supply, finally came to conclusion had to be behind brick wall sitting on a concrete floor rising to a concrete ceiling. Permission giving by landlords for a building contractor to demolish the wall. Yep there was the cutout and EE switchgear incoming 4 pole 300ma 100amp RCD tripped. The outcome the landlords came to a financial agreement to settle EE loss of revenue and named responsible to EE customer and the fuming blue chip clients.

    It turned out the building had been used for mixing explosives used in the quarry next door and the liquid explosive had somehow got onto and impregnated the cable and would cause showers of sparks when the hacksaw rubbed it.
    Strangest thing ever.
    All my metal tools used on that site turned to rust in a matter of weeks.

    Wouldve been better to use a cartridge spiking gun on them reather than the slow drive hydro. Also a lee vaughan cable id tool wouldve gave an inkling wether the cables were loaded before you went near them (as the noise of a live loaded cable is like a roaring) with a spiking gun. Other ways would’ve been an experienced jointer to split the cable insulation and prove with test lamps as it’s an obvious LV cable rather than HV with the joint arrangement.

Working in process automation and interfacing with sparkies often, your videos are very educational to me. Sometimes I toy with the idea of retraining myself to become a true sparky, but then the bits, bytes and distillation columns keep calling me.. Sometimes I feel torn between these two worlds, lol.

    I would think you could use a clamp ammeter to see if there is current in the cable. Granted, it could be live and not passing current. If the cable has AC on it you can detect that using an RF probe like a telecom tone generator and probe. I like the fact that the spike is definitely going to make the cable safe by shunting it to ground. Great content.

      @petermichaelgreen Год назад

      Good luck detecting anything meaningful on a SWA cable without dismantling the cable first. You might detect some small leakage currents but leakage currents can flow in the armour even if the cable is dead so that still doesn't tell you much.
      The alternative to spiking the cable would presumably be to dismantle it using live working techniques but SWA is not designed to be friendly to live-working.

    Genuine question
    Obviously you can't safe isolate/lock of the breaker as you don't know what one it is so when you have cut through the cable and begin working with them what prevention is in place to stop someone turning on that breaker ? I know it's extremely unlikely

      That's a very good question, I love the video by the way. I'd be concerned over an automatic Changeover Switch.
      Iv had that happen to me once on a testing job. Where the cable was dead and automatically re-energised during testing. The tester came up with 440v and Litterally me and 2 of the cable fitters lads left immediately. We ended up calling UKPN to isolate the 11kv to sub stations in the area. Litterally the cable had just been stripped back too so ever since then we don't cut ones we don't identify. This was over 4 years ago in Earls Court, working for mitre as a subby. It turned out the supply we thought was redundant in the basement, was fed by another substation not controlled by UKPN but London Underground. It wasn't till UKPN turned off 3 surrounding substations we found out where it went. It turns out it was jointed to automatically operated feeders for bank capacitors. Obviously before the building was purchased that piece of land belonged to London Underground so the cable wasn't even on the plans.

      I've used a magnetic field meter with a separate search coil to determine if an swa cables is under load. This works as in close proximity, the fields don't cancel. It was very useful when I had 5 cables down a hole & I needed to cut one of them. As I was able to switch load on & off to all cables, I could check both ways to be absolutely sure. However, it doesn't prove dead which is harder as the earthed armour blocks electric fields.

      the torpedoes are resin filled which goes rock hard so if the cables were live, smashing it with a hammer wouldn't be a good idea.

    To be honest, I can't believe anyone still uses a hydraulic spiking gun. Outlawed by the DNO I worked for decades ago. Shouldn't the gun body be earthed? Y'know, just in case?

      @@residualelectrical we’ll have to agree to differ on the safety of hydraulic spiking guns. If it was earthed it wasn’t clear from the video. Spiking live LV cables is more likely to result in the “hand grenade” result than MV cables. Prospective fault currents can be much higher and clearance times significantly slower than MV. Not to my credit but I have spiked one live 11kV cable in my career - didn’t make any flash or bang (other than the silver gun cartridge, which is really only a pop). I’ve see LV cables take off like a flamethrower!

    Why didn't you use live working techniques for a strip and test ? It's certainly an LV cable with the joints. Spiking is a dangerous game especially when your in a basement, smoke, fumes and fire will fill that space in seconds. Spiking doesn't always mean it's dead either.

      @residualcurrent
      The cable looks like a fairly standard 4 core swa ? Fairly common formlive working, there is companies out there that have live working techniques outside of DNO's.
      LV cables will happily sit there burning for a good while, to that without knowing the source of the cable, you're lucky it wasnt live. The clip of the HV cable is actually a short amount of time as HV's will have better protection and are designed to isolate quickly under fault conditions.
      Spiking a cable would be 1 step to identifying a correct cable, not to prove dead or isolated in any way.
      Just be careful playing with this stuff, it will only bite you once. 👍

      @residualcurrent apologies I didn't mean to sound condescending, seeing the side of this when things go wrong I'm quite "passionate" about things being safe. What was the DNO response to this, did they make any attempt to trace them ?
      Cables outside of DNO usually have better protection so probably wouldn't burn to the extent of Network cables.
      Like I said, I apologise sounding condescending, I love your work, love the videos and specially love the use of tools you show.

    You got problems with your method here that can kill a fellow.
    *Ground could be non-conductive enough that a puddle would electrocute you even from a distance.
    *Both ends of the wire were not secured when cut
    *The cable could be intermittently powering the grid or other system, look off, and then go hot
    *Electricity could flash heat metal and shoot off burning ballistic fragments
    *When you measured continuity you sent a signal through a gigantic cable with your dinky meter thing that might not have enough power to pump a signal down the line, further you called it a "short" which in continuity testing would mean you received a signal(I believe you meant you received no signal.).
