The laboratory is part of the Electrical Engineering department of the University, a premier academic institute in the region, and has been preparing specialists in the field of engineering for more than 66 years.

Installations include an auto-transformer, a testing transformer and measuring equipment for AC voltages up to 750 kilovolts (kV). The equipment supplied by ABB will be used for conducting tests on medium- and high-voltage electrical equipment and will also facilitate research in insulation materials.

“The high-voltage testing equipment from ABB will extend the testing facilities in our university to much higher voltage levels. Moreover, it will now be possible for us to conduct research activities in our own laboratory, improving the quality of education.” – said Prof. Marin Hristov, Rector, Sofia Technical University.

ABB specialists also engage with the students and deliver guest lectures and discussion sessions on relevant topics providing valuable industry and technical insights.

“This initiative is in keeping with our approach of working closely with academia and furthering power research and development” said Giandomenico Rivetti, head of ABB’s High Voltage business, within the company’s Power Products division.



ABB has over 1,300 employees in Bulgaria. Headquartered in Sofia, the company has three production units in the country, located in Petrich, Sevlievo and Rakovski and a service station in Varna. The high voltage products factory in Sevlievo manufactures components for gas -insulated switchgear (GIS), generator circuit breakers (GCB), breakers and modules (B&M) and also undertakes product assembly of metal enclosed capacitor banks (MECB) and high voltage (HV) disconnectors.
