I hate it when that happens! You just stick the screwdriver in for a second to see if it's a real short or if all those fuses were just bad - and bam - the screwdriver sticks. It could happen to anyone.
I think the last picture ("nasty metering") is either a before of the screwdriver fuse or the repair, at least it shows the same arrangement in considerably better shape.
Would be interesting to know where the power comes from - no meter and the meter tails just dangle in mid air. Well, at a closer look... maybe it has been bypassed. The wires are most likely L-L-N-N left to right.
These are DIII type bottle fuses 35, 50 or 63 Ampères on the burn out part. Could have been the mains fuse bypassed, although it may have also space for a kWh meter as well.
By carefully looking at the meter readings of the kWh meter, the first reading is 12419 kWh, the second reading 12420 kWh. That looks a different circuit than the one shorted out by the srewdriver. Russian meters are wired up the same as most European meters. Phase, Phase, Neutral, Neutral.
The panel on the left with no meter has been completely bypassed. (where a meter used to be).
Pretty shonky wiring on these other pictures. The rotary switch may even be a 3 phase arrangement.
The product of rotation, excitation and flux produces electricty.
No way - these are DII (0.5-25amps). I think these two fuses are either the only two circuits for the entire place (maybe 6, 10 or 16 amps) or (looking at some of the other pictures) hot and neutral fuse for the only circuit.
So the last picture is actually the repaired version... nice!
The far left arrangement clearly took the load side conductors directly to the meter line side conductors, bypassing meter and fuses... regarding the burnt panel I'm not sure what happened - either they disconnected the service and taped the wires or they (shoddily) bypassed the meter.
At any rate the key ring (epreventing overfusing) was missing, otherwise the screwdriver trick couldn't have worked at all.
The rotary switch sure is 3 phase... look how the breakers are split over the three wires. 3 3ph breaker hidden by a floating single phase breaker is nice too...
