Dyn11 Connected Group Three Phase Dry Type Transformer 0.4 Low Voltage

The Dyn11 three-phase core-type transformer (0.4kV low-voltage side) is a common distribution transformer. 

Its key features are:
Connection group designation "Dyn11": The high-voltage side adopts a delta (D) connection, the low-voltage side adopts a star (y) connection with the neutral point led out (n), and the phase angle difference between the line voltages of the high and low sides is 30°, with the low-voltage side voltage leading the phase angle corresponding to the 11 o'clock position on the high-voltage side by 11 points.
"Three-phase core type": It adopts a three-phase structure, with the core and windings not immersed in insulating oil but insulated and cooled by air or resin, suitable for places with high fire safety requirements (such as buildings, hospitals, etc.).
Low-voltage side voltage 0.4kV: The rated line voltage on the low-voltage side is 400V (phase voltage 230V), in line with the standards for low-voltage power distribution in civilian and industrial use, and can directly supply power to 380V/220V electrical equipment.
It can effectively achieve the conversion from high voltage (such as 10kV) to low voltage, and the Dyn11 connection method is conducive to suppressing third harmonics and ensuring the power quality of the low-voltage side.
