Cercetare stiintifica

Firma noastra este in continua legatura cu Universitatea Politehnica Bucuresti, in ceea ce priveste cercetarea stiintifica. Incercam sa stabilim o legatura foarte importanta intre cercetare si practica. Participam activ la conferinte si simpozioane nationale si internationale in domeniul monitorizarii si diagnosticarii echipamentelor electrice si sistemelor de izolatie.
