Generator Transformer

Engineered at the Point of Generation.

The power generation system requires transformers that are capable of handling power at high levels and efficiently transferring electricity directly from generators to grid. KLR Transformers manufactures generator step-up transformers that are suitable for these applications, featuring capacities up to 100 MVA, and voltage classes that go up to 132 KV on the HV. We provide custom solutions that include ONAN, ONAF, OFAF or ODAF cooling depending on the specifications for thermal duty.

Generator transformers from us are specifically designed to be used in station auxiliary transformers, and unit-auxiliary transformer applications. They provide high-quality transmission of power and regulation in power generation systems.
