| High Voltage Laboratory

The High Voltage Laboratory operates within the Institute for more than 65 years. It performs, type and special tests in accordance with valid national and international stand-ards (HRN EN, IEC, IEEE, ANSI, GOST, AS, CSA ...) and client’s requests.

Main activities of the Laboratory are research, developmen-tal and commercial testing of electrical equipment, calibra-tion of high voltage measuring systems and electrical field strength meters.

It also provides diagnostic field tests of power and instru-ment transformers.

65 years of experience

Accreditation according to HRN EN ISO/IEC 17025:2007High Voltage Laboratory is ac-credited by the Croatian Accred-itation Agency (HAA), according to the requirements of ISO / IEC 17025:2007 for testing and cali-bration.
