Their main duty is to “step-up” the voltage produced at the nuclear power plant to very high degrees (e.g., 138 kV, 230 kV, 500 kV and over) for effective long-distance transmission, and to “step-down” the voltage at receiving substations for further circulation. They are characterized by their really high power ratings (typically surpassing 100 MVA), complicated building and construction, and on-load faucet changers for voltage regulation.

An oil involved distribution transformer, on the other hand, executes the last step in the power distribution chain. It takes the tool voltage from the transmission lines (e.g., 11 kV, 33 kV) and tips it to the reduced voltages (e.g., 400/230 V) made use of by industrial and residential consumers. You typically locate them on utility poles (pole-mounted) or on ground-level pads (pad-mounted). They are smaller sized, have lower power scores (typically approximately 2,500 kVA), and are created for maximum efficiency at reduced, more consistent tons.
