Incercari de compatibilitate electromagnetica
Incercari de compatibilitate electromagnetica
Primul laborator modern de EMC din Romania
Pentru a dezvolta activitati in domeniul incercarilor, ICMET a infiintat primul laborator modern din Romania pentru incercari compatibilitate electromagnetica (CEM), destinat sa asigure compatibilitatea electromagnetica pentru echipamente electrice si electronice. Laboratorul este rezultatul cooperarii stranse intre ICMET Craiova si Physikalisch Technische Bundesanstalt (PTB) Braunschweig, Germania.
In prezent, incercarile de imunitate si masurarea perturbatiilor conduse executate de catre acest laborator sunt acreditate de catre RENAR. In anul 2000 a fost pusa in functiune camera semi-anecoica, prima de acest fel in Romania.
