Company Profile

In 1978, EMEK commissioned her own research and testing laboratory capable of performing all the routine and type tests of instrument transformers (except the short time current test for current transformers). Later, a 5 meter high climatic room capable of going down to -45C was added to the laboratory. In 1982, EMEK realized the first export of instrument transformers, when 145 kV current and voltage transformers were exported to WAPDA, Pakistan. In 1994, EMEK was granted ISO 9001 certification by the Turkish Standards Institute (TSE). Additionally, EMEK was also accredited with ISO 9001 from Independent International Institutes since 1997, currently EMEK has ISO9001:2008 and 14001:2004 certificates from ABS Quality Evaluations INC valid till 2012.
