Renewal of Tennet's HV substation according to IEC 61850 - Strukton

10 years to retrofit over 145 HV substations.
IEC 61850 Engineering and Training

Project start: 2019 (on-going)

Customer need: implementation of the secondary technology, including the IEC 61850 engineering and protection concept.


This project implies the retrofit of a collossal number of AIS and GIS high-voltage (110kV) substations, which is one of the most ambitious projects Elvexys has ever undertaken.

Elvexys has been given a period of 10 years to carry out this project. Given the extent of the infrastructure to be retrofitted, it is a great challenge to lead all design, test and implentation phases in this time span.
