Power Transformer


1. The power transformer uses the principle of electromagnetic induction to convert the electrical energy generated by the hydro-generator voltage (large current) to higher voltage (small current) and transmit it to the power system, which can greatly reduce the loss of power transmission over long distances, and it is one of the main electrical equipment in the hydropower station.

The low side voltage of the power transformer is the rated voltage output by the hydro-generator, and the high side voltage of the power transformer is the rated voltage connected to the power grid.

2. The classification of power transformers:
A. It is divided into three-phase transformer and single-phase transformer according to the number of phases;
B. It is split into two-winding transformer and three-winding transformer according to the winding points.

Our company can provide various specifications and models of transformers according to customer requirements.
