Exeter University — Protection Study
A detailed protection study for a large university campus
The challenge
Aurora was approached by SSE to carry out a protection study for Exeter University campus. The site is large and consists of three distinct rings, two of which operate normally closed using Translay cable differential protection.
What Aurora did
We carried out an initial short circuit study to validate the system design before developing a detailed protection coordination study for the entire network, covering overcurrent and earth-fault coordination and updating the Translay differential settings.
