DCRP/18/01/PC - Revision to Engineering Recommendation P28 - Voltage fluctuations and the connection of disturbing equipment to transmission systems and distribution networks in the United Kingdom

Target Audience

The requirements in EREC P28 are intended for persons who:

  • propose to connect disturbing equipment to the public electricity supply system that have the potential for causing voltage fluctuations
  • propose to alter disturbing equipment/installations connected to the public electricity supply system that would result in material changes in voltage fluctuations
  • carry out assessments of disturbing equipment and resultant voltage fluctuations
  • measure voltage fluctuations caused by disturbing equipment for the purpose of checking conformance with requirements and limits in EREC P28.

Date Published8 January 2018
Deadline for Responses31 January 2018
Summary

This Distribution Code public consultation is seeking the views from industry stakeholders on the proposed modification to Engineering Recommendation P28, subsequently referred to as EREC P28 Issue 2.

This modification has been prepared under the authority of the Distribution Code Review Panel (DCRP) of Great Britain – EREC P28 being a Qualifying Standard and Licence Standard under the Distribution Code[1]. However, given Engineering Recommendation P28 is also referenced within the Grid Code and there is potential for consequent modification of the Grid Code, the views from Grid Code stakeholders are also being sought.

The DCRP establish and maintain governance arrangements for Qualifying Standards that have a material effect on Users of the Distribution System. Annex 1 documents, such as EREC P28, are approved by the Authority (Ofgem) before publication.

The proposed EREC P28 Issue 2 constitutes a full technical revision of Issue 1 published in 1989 and has been extended, amongst other things, to cover assessment and limits for rapid voltage changes (RVCs).

The review and subsequent revision of EREC P28 has been overseen by a joint Working Group of various key stakeholders with co-ordination provided by the Energy Networks Association (ENA).

DCRP/17/06/PC - Revision to Technical Specification 41-24 (TS 41-24) and Engineering Recommendation S34 (EREC S34)

Target Audience
The guidance in Technical Specification 41-24 (TS 41-24) and Engineering Recommendation S34 (EREC S34) will be of interest to designers of main earthing systems in electrical substations and other installations.
Date Published8 December 2017
Deadline for Responses26 January 2018
Summary

This Distribution Code public consultation is seeking the views from industry stakeholders on the proposed modification to TS 41-24 and EREC S34.

Guidance relating to design, installation, testing and maintenance of main earthing systems in substations and assessing the rise of earth potential at electrical installations will be superseded by the modified TS 41-24 and EREC S34.

The modified TS 41-24 and EREC S34 have been completely re-drafted as a result of the publication of BS EN 50522, “Earthing of power installations exceeding 1 kV a.c.” and the need to update both documents in the light of revised legislation and British Standards. EREC S34 is a more technical supporting document to TS 41-24. The two are extensively cross-referenced and therefore this consultation is for both documents together.

TS 41-24 and EREC S34 are both Annex 1 qualifying standards to the GB Distribution Code and governed by the Distribution Code Review Panel (DCRP). The DCRP establish and maintain governance arrangements for Qualifying Standards that have a material effect on Users of the Distribution System. Annex 1 documents are approved by the Authority (Ofgem) before publication.
