Opens up new opportunities for rail markets
“The innovative use of power semiconductors in a core component such as traction transformers opens up new opportunities for rail markets around the world, and should be extendable across a range of other applications,” said Markus Heimbach, head of the Transformers business, a part of ABB’s Power Products division.
“In addition to its weight and size advantages, the new power electronic traction transformer (PETT) helps improve efficiency and reduces noise levels,” he added.
A pilot PETT installation on trial
As part of a long-term partnership between SBB (Swiss Federal Railway) and ABB, a pilot PETT installation is currently under trial on a shunting locomotive for use on the 15 kV AC and 1.5 kV DC lines at Geneva main railway station.
The innovation is a breakthrough that achieves one of the rail industry’s priority objectives of reducing the weight of on-board components. The traction transformer, which is traditionally made of iron and copper is one of the heavy pieces of equipment on a train.
