Partial renovation of switchgear of Paide 330kW substationPaide, Järvamaa

Partial renovation of the 330 kV switchgear at Paide substation took place over two years, as it was possible to schedule the necessary power cuts in the important 330 kV power grid only in the summer 2012 and 2013. The partial renovation took place in complicated conditions on the territory of a substation with live electrical equipment. A new overhead line cell was built for connecting to the Eesti Power Plant substation, along with new cells and foundations for 330 kV transformers, of which one was replaced with a new one in the framework of a separate procurement. The existing substation building was partially demolished and a new roof was installed on the remaining part of the building, with the building gaining a more modern appearance. New 20 kV switchgear was also built, to which the substation’s new local transformer and reactors were hooked up.
