DNV Kema has ordered two Alstom short circuit generators for the extension of DNV Kema’s high power laboratory in Arnhem, the Netherlands.
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 expanded power supply in DNV Kema‘s High-Power Laboratory will be used to test new transformers, circuit breakers and other components for smart grids to transport high volumes of electricity across great distances, enabling a safe and reliable power infrastructure for the future all over the world.
The test laboratory in Arnhem already has four Alstom short circuit generators in operation since 1970 for the testing of electrical grid components such as high power transformers, circuit breakers and switchgear.
By adding these two identical short circuit generators, each capable to generate a three-phase short-circuit power in the test bay of 2100 MVA (@50Hz), the rating and capacity of this laboratory will be extended by fifty percent so as to capable of testing at ultra-high power for smart grid networks of 800 kV above for transport of electricity across great distances, ready to solve the electricity challenges of the future.
The power generated for one test is comparable to the power supply to 500.000 households. This extension will also create additional test slots reducing the lead time for the current testing activities.
