Earthing Transformer

These transformers are used where there is no neutral earth connection. Connection type in such transformers is in a zigzag (Zn) form. This transformer has three coils; coil of each phase is divided into two equal parts and the end half of coil of the first column is in series with half of coil of the second column in an opposite direction. If necessary, an off-load voltage regulator can be considered in main coils. Borna Electronics is ready to offer services on designing and manufacturing different types of earthing transformers.
