3-Phase Wind Power Transformer is utilized in wind power generation systems for stepping up the voltage or current of the electricity produced by wind turbines. The transformer has wind turbines for generating electricity at a relatively low voltage, normally between 690V-6900V, which is not suitable for they use by most electrical machinery and equipment. But, the transformer steps up the current or voltage of electricity to a higher level, between 33kV-132kV, which is well-suitable for long-distance transmission as well as for they use by electrical equipment. Moreover, 3-Phase Wind Power Transformer has three separate windings, attached to 3 different phases of the electrical power system that enables transformer to handle large power loads and also to operate more efficiently and 1-phase transformer.
