Gold Coast Airport upgrades using OSM Recloser
The Gold Coast Airport Pty Ltd (GCAPL) is a dynamic, growing business which has experienced an average annual growth rate in passenger movements of 16 percent over the past five years. With this expansion comes greater energy consumption to service the growth and the airports existing oil filled feeder recloser was beginning to show its age. While the unit was upgradeable, parts were becoming more and more difficult to obtain and lockouts due to higher loads and faults meant a newer more flexible option was needed to improve reliability of supply.
“Our main concern was improving the current rating over the old unit but other features like automatically clearing transient faults and data logging and reporting were important considerations too”, said GCAP L Asset Services Manager, Geoff Arnold. “In fact, the unit we chose will service us past our current planned infrastructure upgrades – something we didn’t expect”, he said.
Located only minutes from the Gold Coast CBD and so close to the ocean, GCAP L management wanted a unit which was both suitable to the local conditions and had a low environmental impact potential.
Using latest generation solid dielectric vacuum interrupting technology, the NOJA Power OSM Recloser achieved GCAP L of low environmental impact by eliminated the use of oil. The OSM tank and control cubicle are manufactured using stainless steel and the tank bushings are high pollution rated making the unit ideal for coastal applications.
“It was a complete package” announced GCAPL Asset Services Manager, Geoff Arnold. “NOJA Power manufactured and supplied the equipment, engineered the protection settings, coordinated the installation and provided training for our engineers. We are very satisfied with the result.”
