Low-, Medium-, and High-Voltage Testing

Safe equipment & systems, complete process control and well-trained employees play a critical role in preventing electrical failures, reducing outages and avoiding accidents. As one of the world’s leading expert organizations, DEKRA has extensive experience and expertise in the low-, medium-, and high-voltage testing fields, and has provided a large number of manufacturers and power companies with testing and certification services and facilitate them in expanding into global markets.
DEKRA has professional testing labs with multiple accreditations such as ISO/IEC 17065, ISO/IEC 17025 and ISO/IEC 17020. DEKRA has continued to expand its testing capabilities in low-, medium-, and high-voltage fields. In 2009, DEKRA bought out KEMA Quality and in 2017 acquired VEIKI-VNL, a world famous medium- and high-voltage testing lab based in Budapest, Hungary and a member of the Short-Circuit Testing Liaison (STL). In addition, DEKRA is a testing agency certified by Dutch Accreditation Council (RVA).

Having been exploring the low, medium and high-voltage fields in China for more than a decade, DEKRA owns a CB testing lab for low-voltage electrical appliances in China and commits itself to providing one-stop inspection, testing and certification services for local customers.
