Safeguarding the Grid: Comprehensive Testing Services by KEMA Labs

Switchgears and control gears are important nodal points in modern power systems and it is vital that they work reliably. In the context of transmission networks, these devices play a critical role in managing the flow of electricity, ensuring that power is transmitted efficiently from generation sites to distribution networks and end users.

Furthermore, high voltage switchgears and switching devices are essential for protecting critical assets within the power grid. They are designed to isolate faults, preventing damage to equipment and maintaining the stability of the electrical system. One of their key functions is to open fault currents, which occur when there is a break in the circuit. By swiftly isolating these faults, switchgears minimize the risk of widespread outages and ensure the safety and reliability of the power supply.

Our laboratories are equipped to handle a diverse array of testing needs for high voltage switchgears and switching devices. We offer short-circuit testing and certification according to internationally recognized standards such as IEC 62271-100 and ANSI C37.09, ensuring robust performance at high power. The facilities cater to evolving industry demands, with increased short-circuit current testing capabilities up to 1100 and 1200 kV.

The laboratories employ realistic test circuits and cutting-edge test methods, including:

  • Three-phase synthetic testing up to 245 kV
  • Three- or single-phase direct testing up to 72.5 kV
