How 2500KVA Electric Transformers are Made

Great video. Just natural sounds. No bullshit music.

[@DD4DA]

looks like a very serious craftwork. Amazing to see, how a handful people build such one.

[@brunonikodemski2420]

RickFox below had the correct concept, only a few missing washers, many metal chips down into the windings, painter spraying chromate or zinc paint with no mask, and using the old style paper & jute insulation (which actually works good in oil), and no pretesting before final assembly. We did this also, and it was the PCB oils which made these designs durable. Later, some of us got cancer. In the US, this would be a crime against humanity, but no worries over there.

Interesting that they don't do any measurements during the assembly, when any errors would be relatively easy to fix. They only measure when the transformer is already assembled and filled with oil, when any issue is most difficult to fix.

[@robertlong2531]

I'm not an electricity power engineer, but it looks like each low voltage phase (secondaries) consists of 2 windings in parallel. I guess this is simply because a single winding would be to stiff to wind on by hand. The high voltage primaries looks also to have 2 windings each as well, one with taps, the other without. In operation at the lightest loads, the transformer primary would have just the phase windings without taps connected to the incoming supply. As an automatic 'on load tap changer' detects secondary voltage drop with increasing load , tapped windings are switched in parallel to restore the secondary voltage, i.e. automatic tap changing takes place without interruption to the supply.

[@zenonbiusz]

As an electrical engineer, I assure you that you cannot connect windings with different numbers of turns in parallel on one core. Such a connection generates equalizing currents that increase power losses in the transformer.

[@robertlong2531]

@@zenonbiusz Well, surely we can assume these guys know from experience what works ok and that there primary objective here is good voltage regulation. We're not all theorists and there practical solution is two equal parallel windings, but one supporting the other from one of five end taps. With a tap selected that's a potential 1/5 of full full load current mismatch. So that's just a tolerable 1/25 extra as a winding power loss, but importantly no extra winding loss when the transformer is working flat out on full load.

[@zenonbiusz]

@@robertlong2531 I looked this video again. It's different from what you wrote. The transformer has a Dy winding arrangement, meaning the high-voltage windings are connected in a delta, and the low-voltage windings in a star. The entire winding of each high-voltage coil is connected in series, and the taps are located halfway up the coil. That's where the tap is selected, which connects to the beginning of the second half of the winding.

[@phils4634]

Whilst these are rather small transformers, the construction requirements are generally similar throughout all scales. Look how much time and effort goes into just the one; now, consider how much materials / time / effort goes into the very HV "Supergrid" systems, and consider the far, FAR longer lead times for replacement should they be significantly damaged, as we saw in the US Metcalfe attack in 2014 ($15 million in damage over 20 minutes).

[@rocksfire4390]

our military budget costs us 1.5 million a minute, 93 million a hour or 2.2 billion a day. so while 15 million in 20 minutes sounds like a lot, when compared to real wastes of money...it's not even a drop in a bucket. clearly the time and effort required to build these transforms is no joke, still the cost of that attack isn't much in the grand scheme of things. also seems kinda crazy that they wouldn't have replacements ready....but i suppose that shouldn't be unexpected with how lax regulations are for companies.
