Wednesday, August 14, 2013: Transformers are used to solve power quality problems like brown-outs, waveform distortion, to provide surge protection. The different types of transformers available in the market include variable auto transformers, isolation transformers and generator step-up transformers (GSU). These can be liquid-filled or the dry type. In this section, we are featuring the new transformers launched in the last one year. However, companies like GE Industrial, GT Digital, Schneider Electric, Crompton and Greaves, and Siemens have not launched any new transformer in the past one year.
Model: 570 MVA, Brand: ABB, Manufacturer: ABB Ltd, Switzerland
Launched in April 2013, this 570 megavolt ampere (MVA) is the first generator transformer with two primary circuits, purpose built to do the work of two generator transformers, according to the company.
Key features
- The transformer has two low voltage (LV) windings (370 MVA at 19 kV and 200 MVA at 13.8 kV), which are fed power from the gas and steam turbine generators stepped up to 132 kilovolt (kV)
- The transformer adapts an oil-directed forced air cooling (ODAF) system, using radiators with axial flow oil pumps and propeller fans to dissipate the heat caused by the power loss of more than 2 MW inside the transformer

Model: PEAK, Brand: Cooper Power Systems, Manufacturer: Cooper Industries (part of the Eaton Group), Ireland
Launched in February 2013, the PEAK transformers are uniquely designed to provide additional capability to manage increased loads and temporary overload capacity, without accelerating the loss of insulation system life.
Key features
- Available in 75°C average winding rise (AWR) and 65/75°C AWR in configurations of single-phase pole- and pad-mounted, as well as three-phase pad-mounted and substation variants
- For applications where a smaller footprint and a lighter transformer unit is needed, a 75°C AWR PEAK transformer is recommended
- When additional overload capacity is most important to manage increased loads or peaks in demand, a 65/75°C AWR PEAK transformer is recommended
