ENA Doc 042-2018

The objective of this guideline is to assist network service providers (and network operators) in identifying actions, considerations and assessing risks prior to manually reclosing high voltage distribution and transmission lines and associated electrical apparatus following a fault operation. This guideline does not stipulate prescriptive details in the operation of high voltage distribution and transmission lines and it is envisaged that individual organisations will establish their own safety management systems and operational procedures for manually reclosing high voltage distribution and transmission lines and associated electrical apparatus following a fault operation. This guideline will encourage a national convergence in approach towards best practice in regard to the management of risk associated with the re-energising of electrical apparatus and will also facilitate community and emergency services awareness regarding the potential dangers associated with electrical apparatus during fault situations..

This Guideline is based on ENA NENS 07-2006 which was originally based on ESAA NENS 07-2003.
