Description
Unit transformers are installed at thermal, hydro, solar and wind power plants. Insulation is oil, the units are built to IEC and ANSI, and Eco and ATEX versions are available. The transformer steps up the voltage of the generator or inverter block to the level of the grid to which the station is connected.
