Magnetic Material Laboratory
Core of electrical machines such as Transformers, Motors, Generators etc. are made up of soft magnetic steels i.e. CRGO (for transformers) & CRNO (for rotating machines). Efficiency of these electrical machines, which is one of important parameters, depends on core material used. Hence, evaluation of these core materials is essential. ERDA has state-of-the-art test laboratory to undertake evaluation of soft magnetic materials evaluation i.e. CRGO & CRNO as per Indian & International Standards.
