They might care about horrific electrical accidents. With High voltage/high Amperage acidents - your lucky if you die on the spot otherwise you last a few days

They might care about horrific electrical accidents. With High voltage/high Amperage acidents - your lucky if you die on the spot otherwise you last a few days in intensive care with limbs blown off and your internal organs destroyed

Mines are such dangerous places that horrific electrical accidents may happen occasionally and it's still an improvement from the current situation.

  I think the end goal is to not have humans on the field unless something untoward happens.

You can couple mechanically, but get a human to check before actually supplying power. Seems like a simple thing to fix.

Like EV chargers, the couplers and protocols are designed with safety in mind. It's not like you're plugging in to a giant electrical socket and throwing a switch. The system handshakes, runs tests for current leakage, etc. If anything doesn't check out 100%, it won't energise.

  Have you not heard of murphy's law, or not thought that miners might take shortcuts and bodge a connection.

    Then where are all the folks dying today from the high power Tesla Supercharger incidents? 2MW or 250kW, either way you'll be dead if that accidentally lights you up. If you set the system up right, you can't do that in a meaningful way, and if you do... well there's 2MW of deterrent. It only takes one workplace incident like that to make sure the bosses put some measures in place to make sure it never happens again. And keep in mind: at that kind of power level, you aren't just zapping one person... it's probably going to destroy a LOT of equipment and infrastructure... so there's a hefty monetary incentive to make sure that never happens.

      Consumer EV charging is basically a cooker circuit. When you go to serious Amperage and High/Medium Voltages its a completely different ball game.

        Sure, the wall chargers you have in your house are. You think the 400V, 625A circuits (250kW chargers) are just dumb circuits though? Fairly certain they have temperature and voltage monitoring on both sides of the cable and both sides of the connector, all to monitor for any issues with either the connector or the cable continuously. Anything goes wrong, gets to hot, etc? It kills power. You're right though. Medium voltage circuits (and above) are going to be much more complex. The fact is, once you start operating at medium voltage and above, stuff that previously was an insulator may not actually be as insulating as you think...
