LV fuse replacement safety

Hi all I know that in this country and possibly in Europe too when DNO faultsmen  are replacing LV fuses in substations and distribution  pillars  they generally wear lots of PPE  sensible in view of  the flash and bang you get if there's still a fault however I saw a video from India  where the guy literally stood on top of the transformer  and put fusewire  a cross the LV terminals where I'm guessing a proper fuse should go  there's no checking contacts  are isolated before putting the wire on. Similar with the HV side the videos by BEEE WORKS  The videos are only a year or 2 old

  • I assume Kelly refers to this video. 

    He does actually turn off the isolator  built into the transformer, and as he uses a neon indicator to check for live when he has finished, I presume he has the option of using it to check before he starts as well - we do not know how the video has been edited.

    I agree it is careless and as an educational video likely to cause more problems than it solves.

    The sheer weight of wire tangles around those horns suggests that those  fence wire ‘LT fuses’ blow quite often, and no one ever removes the old stuff. He seems a bit unsure about 1 strand or two in parallel per phase.

    India is on my list of places where the normal rules of the game do not seem to apply, having been out there for work on a couple of occasions. I do recall in the supply to a clinic looking up at the HV feed to realise there was a splice (like you might do in a rope) with loose ends sticking out like a hedgehog, swaying about merrily in mid span on one of the phases, and on another occasion there was a hotel meeting room prepared for a conference, and to get power to the tables for the guests laptops, phone chargers etc (imagine a layout like lots of tables to watch a cabaret ) strips of carpet tape ran zig zag from table to table and at each intersection a pair of red and black singles emerged from a slot in the tape into a twist and tape joint for a 15A socket…

    With transformers on the ground and open, for a while that country held the prize in my list for dodgy, much worse than the former eastern bloc. Then I went to South America for a while, it is fair to say that India is now in 2nd place.
