Medium Voltage & High Voltage Equipment
MV & HV Equipment in Transmission and Distribution Systems
For power grid operators and utility companies the reliability of their power transmission and distribution equipment installed in their network is vital. Investments in grid renewal and extensions are costly; equipment needs to last for decades. On top of that, it is important to eliminate electrical failures, reduce power outages, and increase the safety of people who work in critical environments.
A safe power grid, safe equipment and systems, adequate processes and trained employees are paramount. By working with an independent third party like DEKRA, manufacturers can prove that their products have been tested according to international standards, meet end-user specifications, and relevant safety regulations. At the same time, grid operators and utility companies can rely on our certificates, reports, and verification services to assure the required level of reliability and safety.
The STL (Short-Circuit Testing Liaison) is an international forum for voluntary collaboration between testing organizations in the field of HV. The objective of the STL is to harmonize the implementation of IEC and regional standards for type testing of HV electrical equipment. VEIKI-VNL, a member of the Short-Circuit Testing Liaison (STL), was acquired by DEKRA in 2017.
High voltage laboratory
DEKRA is an approved third party inspection and testing company by power grid operators and utility companies in a large number of countries in Europe, Middle East, Asia and South America. VEIKI-VNL, based in Budapest, Hungary, joined the DEKRA family in 2017 and complements DEKRA’s capabilities with a broad range of in-house testing services, e.g. large capacity test, high voltage test, temperature rise test and environmental test, etc. VEIKI-VNL supplies its services to energy utility companies in over 40 countries on all continents.
Typical services we offer include type testing, product certification, production supervision, factory acceptance tests, quality assurance, factory inspections, non-destructive testing, failure investigations, and inspections as part of asset management programs. We believe testing should be done as close as possible to manufacturers and end users. That’s why we offer testing near your premises, either in one of the DEKRA laboratories, your own laboratory under DEKRA supervision or in one of our associated third-party laboratories under DEKRA supervision.
We provide local services to help you extend your global reach
Our testing laboratories are located in the Netherlands, Hungary, the United Arab Emirates and China. In addition, our Dutch, Hungarian, and China-based high-voltage inspection teams witness type testing at manufacturers’ sites and/or third-party laboratories around the world, including in Europe, the Middle East, South Korea, China, Japan and the USA.
Our certificates and test reports are widely recognized and accepted by grid operators, utility companies, end users, and other stakeholders around the world. We can provide you with a reference list on request. The DEKRA services cover a wide range of products and standards for which we are accredited as a testing laboratory (ISO-IEC 17025), as an inspection body (ISO-IEC 17020) and as a Certification Body (ISO-IEC 17065). Our employees are highly qualified and experienced, and personal references can be provided on request.
The DEKRA Middle East Testing Laboratory, located in Dubai, UAE, performs tests for products such as switchgear assemblies, cables, busbar trunking systems and packaged substations in line with national and international standards and client-specific requirements. In addition, preliminary testing is performed during the product design phase.
