EUROGULF Transformers operates a modern, fully automatic High Voltage Test Laboratory engineered to verify the mechanical, thermal, and electrical performance of power and distribution transformers. Calibrated in full alignment with international standards — including IEC 60076, IEEE, ANSI, BS, IS, and NEMA — our automated test bay guarantees precision diagnostic reporting, total transparency, and uncompromised quality assurance for global energy markets and EPC contractors.
Test Laboratory Capacity & Capabilities
Our purpose-built, electrically isolated test hall in Sharjah, UAE is outfitted with high-precision digital measuring systems, impulse generators, and computerized data acquisition software. All measurement values are captured automatically into dedicated test software, eliminating manual logging error and generating verified electronic reports for witnessed or factory acceptance testing (FAT).

KEMA & CESI Type Tested
EUROGULF transformer designs are independently type-tested and certified by internationally accredited laboratories including KEMA (Netherlands) and CESI (Italy), proving robust performance under extreme operating stresses.
Automated Data Acquisition
Integrated computerized software captures all electrical parameters instantly without human intervention, ensuring authentic, repeatable test reports with zero margin for error.
Interlocked Safety Systems
Our high-voltage lab is equipped with safety enclosures, emergency tripping interlocks, infrared light curtains, and zero-ground monitoring to safeguard engineers and client representatives during FAT.
