- Testing Infrastructure and Capacity
KEMA Labs operates multiple high power laboratories across different locations.
Available short circuit power range:
- From 2,000 MVA
- Up to 15,000 MVA three-phase
Key advantage:
- One of the widest testing ranges available in independent third-party laboratories
What is short circuit power capacity?
Short circuit power capacity indicates the maximum electrical power level that a laboratory can reproduce during simulated fault conditions. In high power testing, this is a critical parameter because it determines whether the laboratory can realistically stress electrical components under the same extreme conditions they may face in transmission and distribution networks. KEMA Labs High Power Laboratories cover a range from 2,000 MVA up to 15,000 MVA three-phase, enabling tests on a broad spectrum of equipment and system ratings. This capacity allows manufacturers and utilities to verify the behavior, resistance and safety of components when exposed to severe electrical faults, before they are installed in real operating environments.
- Engineering Expertise and Efficiency
These industry-leading facilities are supported by highly qualified test engineers and extensive technical experience.
Key benefits include high flexibility in testing configurations, efficient execution of test procedures and cost-effective testing solutions.
In short: advanced infrastructure combined with expert engineers ensures reliable and efficient testing.
- Certification and Results
After successful testing, components receive a KEMA Labs type test certificate.
Certification value:
- Globally recognized
- Proof of quality and reliability
What does a KEMA type test certificate guarantee?
A KEMA type test certificate confirms that a component has successfully completed the required tests under defined laboratory conditions and in accordance with applicable international or regional standards. For manufacturers, it provides recognized evidence that the product has been tested for performance, safety and reliability. For utilities, grid operators and technical buyers, it helps support procurement decisions by offering independent third-party validation from KEMA Labs. The certificate is therefore not simply a formal document: it is a technical proof point that the tested component has met demanding requirements and can be considered suitable for use in critical electrical infrastructure.
