DNV KEMA has ordered two additional Alstom short-circuit generators for the extension of its high-power laboratory in Arnhem, Netherlands. DNV KEMA says the laboratory will test new transformers, circuit breakers and other components for so-called "super grids" to transport high volumes of electricity across great distances.

The complete project consists of the supply and installation of two air-cooled short-circuit generators and auxiliary systems such as a drive system, normal excitation system and lube oil system. All systems should be operational in 2015.

The test laboratory in Arnhem already has four Alstom short-circuit generators in operation since 1970. By adding two more units, DNV KEMA says the rating and capacity of the lab will be extended by 50%, allowing it to test at ultra-high-power for super grid networks of 800 kV and above.
