Short historyShort history

• ICMET Laboratories Department (HV & HP) was built within 1968-1974, extended in 1978 and 1981 as part of CIMAE (Electrotechnical Industrial Group) based in Craiova at ELECTROPUTERE.

• Essential contribution for the implementation of 220 and 400 kV insulation classes in Romania

• Registered in 1982 at OMPI Geneva (World Intellectual Property Organization)

• From 1990: Independent government-owned Research, Development & Testing National Institute for Electrical Engineering (self-financed) under aegis of Economy and Commerce Ministry

Scope of DevelopmentScope of Development

• Stabilization of the Romanian Electrical Engineering Industry(this uses almost 20% of the entire Romanian labour force)

• Improvement of Romanian electrical equipment quality

• Increase of reliability in SEN (National Power System) with major implication in East-West energy transfer

• Infrastructure assurance for the European Integration of theRomanian Economy

• Assurance of testing services in the regulated EU fields Safety & EMC

• Growth of competition capacity on the market of testing services at Regional and International level, representing today over 70% of the turn-over for Labs Department
