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.
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.
@@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.
@@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.
Amazing crafstmanship & industrial skilled workers, but it's sad they're not being provided with PPE (personal protective equipment) such as respirators (masks) or gloves when handling the solutions, torches and solder as well as the painter.
Actually some of those welds sucked! They will likely fail under pressure and expansion/contraction due to heating/cooling cycles. Where is the quality control for this company?

I'm no expert but if that transformer is for step down then shouldn't the high voltage winding, which would be the primary, be fitted nearest to the core? Or is that too high a risk of insulation break down?
At 4:43 I was a little concerned that the torch carbonized the cloth on the adjacent cables. Is it possible that arcing could occur at that point causing failure of the entire transformer?

The complete transformer may handle kilovolts but the potential difference between the individual windings is so low it can be insulated by only a coat of varnish and some very thin cloth.

I have watched 20..30 similar videos, I find it amazing that these people produce complex products with such simple tools.

pln kayaknya beli alat2 seperti ini, padahal kalau bikin sendiri akan sangat menghemat anggaran
Кругом медь! Нифига себе
Vcs trabalham de um jeito tão arcaico, e mesmo assim, o trabalho fica
espetacular!
I have watched 20..30 similar videos, I find it amazing that these people produce complex products with such simple tools. But now, for the first time, I have to say that using a hammer handle is just stupid. A wooden or plastic hammer costs a few cents. But a simple piece of wood would also do, as we will see later.
Amazing video. I have fix small transformers and is really cool when you understand how they work.
pasquitan people....genius.....not poor...very rich in factory
Es increíble como trabajan sin usar ningún tipo de protección, además con los químicos en contacto directo con su piel, sin zapatos especiales de protección, guantes ni otros sistema para salvaguardar su integridad física. Mis respetos.
Ok..so who's doing the quality control...geez
There's QA?

Thats essentially how it's done.. Although in modern factories they use machines for rolling, and instead of shit on of what I'm assuming is cable they use full aluminum sheets
