Aurora was contracted by High Voltage Power Systems Ltd, to carry out a protection study for a planned major refurbishment of the Basingstoke hospital.

Aurora’s scope included organising a site survey for the existing protection devices, and equipment; reviewing the proposed SLDs to ensure that sufficient reliability was maintained in the emergency system, before creating a model of the whole electrical system in DIgSILENT Powerfactory. Once the DIgSILENT model was created, a number of different protection coordination cases were carried out for the normal and emergency operation cases.
