KEMA-Powertest continuously invests in new equipment, improved testing techniques, as well as personnel training to stay at the leading edge of technology. The laboratory is accredited to ISO 17025 by the American Association of Laboratory Accreditation. We can provide proposals and quotes and assist with test programs to be performed at the KEMA High-Power or High-Voltage Laboratories in the Netherlands. We can also coordinate with these labs to perform test programs they send.

In addition to high-quality electrical and mechanical testing services, we can conduct field-testing and provide engineering consulting services such as failure investigations for equipment, including  switchgear, circuit breakers, transformers, and cables.
