Switchgears and control gears are important nodal points in modern power systems and it is vital that they work reliably .

Our independent testing, to the highest internationally recognized standards, allows you to prove to grid operators that your circuit breakers deliver robust short-circuit performance for today’s networks.

Kema Labs offers short-circuit testing and certification of high voltage circuit breakers according to global standards such as IEC 62271-100 and ANSI C37.09. We can also test according to local standards if required.

Notwithstanding the lack of consolidated international standards, Kema Labs is the pioneer and market leader in HVDC circuit breaker testing and through our Laboratories and skills we partner in a EU-funded research project for the development and testing of HVDC circuit breaker prototypes.
