FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering, particularly to power transformers at industrial and railway substations. Proposed adjustable transformer comprises magnetic core (1) with primary and secondary windings comprising several coils (4 and 5) connected to switches (6, 7, 8, 9, 10 and 11). Coils (4) of primaries and (5) of secondaries are fitted on core (1), its all rods having identical cross section area. Note that all aforesaid coils feature equal number of turns.
EFFECT: simpler design, possibility to smoothly adjust power.
