Splet01. dec. 2024 · The power is obtained from the 220 kV or 132 kV or 110 kV or 66 kV, three-phase, effectively earthed transmission network of the State Electricity Board, through single-phase transformers or Scott connected … SpletIn a transformer, magnetic flux is produced as a result of the varying electric field (i.e., alternating current). The change in magnetic flux in a transformer happens due to the variations in the current supplied by the AC source. AC source provides an alternating current that varies from negative to positive values in each cycle.
