1. Carry out a series of investigative short circuit tests at an independent test station on a range of commonly used distribution switchgear and publish revised fault level ratings where appropriate.
2. Calculate the actual fault level at distribution substations and the level of typical attenuation.
3. Assess the available fault level headroom.
4. Publish a report outlining the details of the investigations and the potential for application of revised ratings.
 

1. Completion of the short circuit tests and reports.
2. Table of actual fault levels at distribution substations.
3. Table of actual fault level headroom.
