Centralised MV Powerplant Transformer-Oil Type

Oil Filled Amorphous Metal Distribution Transformers

 

Up to 3MVA & 33Kv

 

This transformer is an energy saving and

hermetically closed oil-filled transformer which is

produced by winding a core made of Nano-crystalline

amorphous glass metal ribbon. This transformer is

capable of being constructed with two to four

low voltage windings of foil and a high voltage

disc winding. The transformer can accommodate

two asymmetrically loaded systems without mutual

influence on the low voltage side, while providing

an extremely low core loss under low power consumption.

By coupling of multiple low voltage windings and low no

load losses resulting in low life cycle and maintenance costs.

This transformer has 70% lesser no load losses in comparison

to traditional laminated core transformers.

This transformer is ideal for large PV plants that work with

several central inverters which feed with maximum system

yield to the medium voltage grid. Upon request the transformer

can be designed with a maximum of four low voltage windings.

The vector group Dyn5yn5 then increases up to a maximum

of Dyn5yn5yn5yn5.
