Trying to imagine the electronic networks required for a 100,000 seat stadium is nearly impossible. From the huge lighting towers that illuminate the ground, through to the last television point, designing and implementing solutions for the MCG was a three-and-a-half year project for Downer Engineering.
Downer's solutions included the complete design coordination and installation of the various lighting, power reticulation, distribution, communications and security systems, says project manager Karoy Balazs.
"The electrical and communications packages included five new main switchboards, standby generators, more than 300 distribution switchboards, main and sub-main cabling reticulation, as well as general-purpose, special and feature lighting," he says.
All main switchboards, generators and tower lighting systems are connected to a Programmable Control and Monitoring System (PCMS), which continuously monitors inputs and set points for correct operation. To provide a seamless backup in case of a partial or full power outage, Downer installed a dual-redundant fibre loop around the ground, which maintains system integrity.
