Control equipment and switchgear assemblies in power plants or substations must be able to switch high voltages and thus require efficient cooling systems.

Coupled numerical simulations are a valuable tool in this respect as they can predict electrical heating power, the three-dimensional air flow and temperature distribution in switching stations in interaction with electricity network parameters.

This simulation approach helps to identify potential hot spots and to take appropriate measures in design, construction and material selection. In addition, the Energy Department also offers simulation support in the development of low-voltage switchgear. The use of coupled numerical simulation methods minimises the need for experimental tests on expensive prototypes and thus helps to reduce the time-to-market for new products.
