The High Power Laboratory performs, type and special tests in accordance with valid national and international standards (HRN EN, IEC, UL, GOST etc.). Its testing capabilities, especially high-current tests at low voltages (short-circuit current tests and making/breaking capacity), make it unique in the Republic of Croatia. It also provides diagnostic field tests of HV circuit breakers, metal-enclosed SF6 switchgear and controlgear and metal-enclosed busbars.
The Laboratory is accredited according to HRN EN ISO/IEC 17025:2007 for “current testing of electric power equipment and testing of conformity of electrical equipment for use within certain voltage limits“.
