I have plenty of experience in the field I used to install service and later manufacture generating plant. I learnt one important thing when I first started from my employer, if any one but any one comes and says hurry up, tell them that they have the choice of the job takes as long as required to do it safely or they can have the plant shut down for three months while the health and safety investigate what went wrong. I have worked on generators for the likes Of Ciba Gigy and Dows and at no time did I get the hurry up.
That indecent was not the fault of an analogue meter. The meter in question he was using looked like a Fluke DMM. The switch gear either did not have automatic lock out or that had been disabled.
The argument here is not about safety at work with HT systems but as to the safety of analogue meters when used in the correct environment and the correct way. I used analogue entirely until around 2006 by which time digital were robust and cheap enough for me to go over to them in the main. I personally never worked on anything above 1100 volts as that was the voltage of the largest gen sets I ever worked with. I now only service a few smaller sets the largest of which is 150 KVA 415 volt.
I can assure you that safety while working is my priority to the point that I have walked off jobs in the past as the site or other workers were not safe to be around, better no pay than dead.
Well your attitude makes me think of people who think the bible is absolutely true and not a total work of fiction with a few life codes thrown in.
All this because on page 1 I had the misfortune to write "never use an analog multimeter on high energy circuit."
Do you have Alzheimer's or are you just stupid?
Last time I looked this was an Electronics forum, and servicing HV lines, multi-megawatt generators or industrial induction furnaces is only a curiosity to most...
Almost all analog multimeters are from an era before safety standards. It doesn't mean they are unsafe by nature, they are such a big multimeter with plenty of room for spacings, big fuses- compared to small DMM's.
The Simpson 260 analog VOM has undergone many revisions over the decades, and there is the safety version Model 260-9S.
Cheap chinese multimeters with fake IEC 61010 approvals are garbage and much less safe than old bakelite.
That arc-flash video determined he was measuring phase-phase voltage in a 2.3kV MCC
Voltage measurement
...
The multimeter may only be operated by persons who are capable of recognizing contact hazards and taking the appropriate safety precautions. Contact hazards exist anywhere where voltages of greater than 33 V RMS may occur.
For those who haven't seen it or worn it, proper arc flash protection looks like this:
Does Proper PPE Protect me from Injury?
Protective equipment is designed to limit burns to second degree burns.
An arc blast can knock people off of elevated platforms or blow doors or shrapnel across the room, to which the proper arc flash PPE provides little to no protection
One of the lesser known risks is the sudden UV burst which burns your retinas out instantly, even if you're not actually affected by the burning hot metal spraying all over you.
The arc blast will likely vaporize all solid copper conductors, which will expand up to 67,000 times their original volume

concussions, collapsed lungs, hearing loss, shrapnel injuries, and broken bones are the common injuries.

Wonder how effective those outfits are. I used to have a plasma cutter rated at 300 volts Dc 55 amps output, that would spray out an plasma nine inches long and cut through anything including bricks ( I tried it) a copper plasma is used as anti tank weapon, so I wonder if the copper bus bar turned into a plasma and came in the direction of that suits wearer what protection id would afford, and before any one jumps down my throat I am sure it is better than nothing.
When checking leads acid batteries a face shield is not over kill, I have seen several batteries explode from over gassing and just a small spark, I have had that happen to me with a car battery when I was around fourteen and disconnected a charger incorrectly, I was lucky the acid only went on my hands and clothes, I washed it off straight away but when my mother took my clothes out of the washer she wondered why they were full of holes.
