The HEAF Project was planned as a three-year programme to be conducted by USNRC at a facility in the United States. The project's aim is to conduct experiments in order to explore the basic configurations, failure modes and effects of high energy arc faults (HEAF) events. The equipment to be tested and considered primarily consists of switchgears and bussing components. Since the switchgears and other equipment necessary for testing is very expensive, the programme relies on signatories' in-kind contributions.
The project has two objectives:
A significant amount of full size equipment has been tested. The initial testing took place in June 2014 in the presence of project members followed by 3 further campaigns in November 2014, March 2015 and October 2015. No further tests are currently planned. Data including high-speed high-definition (HD) video has been captured by the USNRC team and will be shared amongst other participants during February 2016. Partners will then carry out their analyses of the data and should be able to contribute to the final report after this point. The first draft of the final report is now planned for delivery in June 2016, which necessitates an extension to the project end date to December 2016.
