Project: New Transformer / Distribution Substations with Secondary and Protection Systems for Upgrading the Grid

In view of the increasing infeed of renewable energies, e.g from photovoltaic systems, and the ever greater impact on the electricity grid and the grid infrastructure, the municipal utility company “Fröndenberg” wanted to extend and modernise their transformer and distribution stations together with AUTEC.

Within the framework of the required modernisation of the existing switch control panels in the Schwitten distribution substation AUTEC was commissioned by “GA Energieanlagenbau Nord GmbH” to assemble and supply more than 40 switch cabinets with secondary equipment. This so-called secondary equipment comprised protection systems such as directional and non-directional overcurrent protection as well as transformer differential protection and line differential protection.
