Mobile Electrics (Mobile Automation ) has successfully completed a major electrical infrastructure and control system upgrade at Sugar Australia's Kilsyth plant in Victoria.
The scope of work included a new mains supply with a 1000 KVA kiosk installation, a new capacity control device and meter panel as well as a new main switchboard.
The challenging plant upgrades consisted of the design and manufacture of new electrical control cubicles and modifications to the existing control boards on site. Wiring for all the new pieces of equipment and apparatus throughout the plant was carefully selected to ensure that it complied with the installation environment.
The plant upgrades project had a critical time-frame for completion since the plant could be shut down only for short periods to ensure continuity of production.
Mobile Electrics worked around this by scheduling a team of 10 electricians, 2 engineers and 4 apprentices to be available as the system was shut down. Project co-ordination with the on-site mechanical team was also required. The work progressed smoothly, enabling the time deadlines to be met.
An Allen Bradley SLC 500 PLC was specified to ensure seamless compatibility with the existing system. A risk assessment was carried out and the machineries safety system was upgraded to comply with the risk assessment outcome and monitored via a Pilz programmable safety PLC.
All plant motors determined to be located in hazardous locations were changed to comply with AS/NZS 60079-14 with appropriate AUSEx or IECEx approvals and fitted with Danfoss variable speed drives.
The final testing and commissioning was completed, and a final inspection carried out by an independent inspection company. The documentation was finalised utilising Mobile Electrics’ new in-house CAD system, compiled together with the hazardous area verification dossier and forwarded to the client.
