How many windings do autotransformers have
Web25 okt. 2016 · In the sketch, the primary winding is put around the secondary, giving the entire primary winding a larger diameter. And each winding consists of several layers, the outer having a larger diameter than the inner. So, even if the length of wires is known, the number of windings can not be determined @resident_heretic wrote about … Webwindings but uses part of the winding from both sides, allowing a much more compact design. The spectrum of autotransformers ranges from small distribution system transformers (from 1000 kVA) to large transformers of several hun-dred MVA. Their use becomes more interesting, the less the ratio between the high-voltage (HV)
