The work performed by Maschinenfabrik Reinhausen (MR) included the replacement of the two on-load tap-changer inserts for longitudinal and diagonal regulation, which previously used oil technology, with modern on-load tap-changer inserts with vacuum switch technology, the manufacturer states in the press release.
Other improvements included installation of new voltage regulators with ISM® technology, and three motor-drive units, which have been newly installed to ensure the safe and reliable drive of the tap changer and de-energized tap-changer.
The entire system, consisting of drives and a voltage regulator, was validated in a special testing facility.
