Three-phase transformer contains-
Three primary and three secondary windings
Three primary and three secondary windings - This option correctly describes the standard configuration of a three-phase transformer, having one primary and one secondary winding set for each of the three phases. Therefore, a three-phase transformer contains three primary windings and three secondary windings.
Important Questions from Three Phase Transformer Basics
The core of a three-phase, 50 Hz, 1000/400 V delta/star: 300 kVA core type transformer operated with a flux of 0.04 wb. Find the EMF per turn.
A three-phase transformer has 600 primary turns and 200 secondary turns. If the supply voltage is 1000 V, find the secondary line voltage on no-load when the windings are connected in star–delta.
In Three Phase Transformer, The load Current is 139.1 A, and Secondary Voltage is 415 V. The Rating of the Transformer would be:
Three impedances, each of (3−4j) Ω, are connected in delta to a 200 V, three-phase, 50 Hz balanced supply. What are the values of line current and phase current, respectively, in the delta-connected load?
