Eaton has installed a medium voltage (MV) system for a new hospital in Zwolle, The Netherlands. The Isala Klinieken is the largest non-academic hospital in the country, it uses the MV switchgear equipment to ensure an electrical energy supply for the complex.
The hospital has a flexible 10 kV power supply system focused on minimising low-voltage distribution losses.
“It is important that this voltage level is managed properly and that a fully reliable system is used to distribute it to all the wings of the building”, said specialist engineer Gert Jan van Tolij from ICI, the consortium responsible for the installation hospital project.
The design uses two 10 kV ring circuits and allows the supply to come from either mains or emergency power generators as required. One ring circuit supplies the preferential power supply system, and the other the non-preferential one. Any power outages in the preferential system are absorbed by emergency power generators.
Open ring circuits allow faulty sections to be isolated, allowing other sections to remain functional.
The switchgear panel is an Eaton Power Xpert FMX with an IEC single busbar and air-insulated MV switchgear for voltages up to 24 kV. Four emergency power generators are available to supply 1 MVA each to the preferential busbar of the Power Xpert FMX.
