By anc, 8 June 2017

Tagged CIGRE, SCB3, substations

The Chairman of Study Committee B3, Australian Terry Krieg said that Transmission and Distribution substations continue to play a central role within electricity networks in providing safe and reliable energy to consumers and that the Study Committee aims to serve a broad range of target groups in the power industry with our focus on not just the technical,but also the economic, environmental and social aspects of substations.

The annual report summarises the work that has taken place within the Study Committee over the last year including events held, working groups supported, publications and the agreed preferential subjects for the Paris Session 2018.


Recent publications for Study Committee B3 include:

  • TB 660 - Saving through optimised maintenance in air insulated substations
  • TB 674 - Benefits of PD diagnosis on  GIS condition assessment
  • TB 686 - Internal Arc effects in Medium Voltage Switchgear (l-52kV)

 Work continued in 2016 on the Substation green book, the first of two SC B3 Green Book projects. These works will be used to encapsulate and present the consolidated information available in the CIGRE body of work in relation to Substations and to identify new study areas for future direction of B3 activities. This first Green Book will be published in late 2017. The second green book on SF6 was launched in 2016 for publication in 2019.
