Product Description
Dry-type transformers are different from oil-immersed transformers. Their windings and iron cores are not immersed in insulating oil but use air or other gases as the insulation and cooling media. This design endows dry-type three-phase double-winding distribution transformers with advantages such as fire prevention, explosion prevention, no pollution, and simple maintenance. They are suitable for places with high requirements for safety and the environment, such as urban power grids, high-rise buildings, hospitals, schools, etc.

How to Form a Three-phase Transformer with Three Single-phase Transformers?
To form a three phase 50 KVA dry resin transformer with three single - phase transformers, follow these steps:
Connection on the input side: Connect the input terminals of the three single - phase transformers to the three phases of the power supply respectively. Ensure that the phase sequence is correct, usually corresponding to A, B, and C phases.
Output side connection: There are two common connection methods for the output side.
Star (Y) connection: Connect one end of each single - phase transformer's secondary winding together to form the neutral point. Then, the other three ends are the three - phase output terminals.
Delta (Δ) connection: Connect the end of one single - phase transformer's secondary winding to the start of the next one in sequence, forming a closed loop, and the connection points are the three - phase output terminals.
Ensure balance: Make sure the output voltages of the three single - phase transformers are equal. If necessary, adjust the magnetic core saturation or tap positions of the step down and step up distribution transformers to achieve voltage balance.
