Distribution transformer substation in Labore was built in 1968. In 2001 the substation was renwed due to obsolety and change from 10 kV to 20 kV. High voltage air-insulated 110 kV switchyard was replaced by a GIS switchyard and secondary equipment was replaced with new devices.

The secondary equipment was than almost 20 years old and on the ege of its lifetime, spareparts were also not suppliable anymore. Therefore appropriate maintenance of the control and protection system was not possible and reliability of the operation with such equipment was critical. The renewal was therefore very important for further reliable operation of this distribution transformer substation.
