STATE OF THE ART FACILITIES

Testing

Our world class power transformer manufacturing facility is divided into three major workshops: the electrical assembly operations, the mechanical welding and surface treatment painting operations, and the electrically isolated high voltage test laboratory.

We have a modern and efficient test room equipped with high precision equipment calibrated to meet the requirement of IEC 76, IEEE, BS, IS and NEMA standards to conduct routine, type and special tests according to customer requirements, the national and international standards and company procedures.All transformers manufactured by EUROGULF are tested according to IEC standards. Our test lab is fully automatic wherein all values are captured into a software, using which, all test reports are generated at the end.

The laboratory is equipped to test  transformers up to:
