Practical Perspective on Recloser Training

NOJA Powers Brisbane Clem Jones Tunnel

Engineering trainees in Hermosillo, Mexico, were treated to an impromptu practical demonstration when a nearby OSM Recloser operated to lockout on a 3kA earth fault.

The OSM Recloser was minutes away from where Service Director Oleg Samarski was conducting a training session on the OSM Recloser to the installation and service crew. The training covered basic recloser configuration theory and applications and advanced data analysis using TELUS - the OSM Recloser's built-in data analysis software.

Oleg used this opportunity to demonstrate the OSM's advanced data-logging and reporting functionalities in a real-world setting. Connection was made to the device using TELUS software and the data was downloaded and analysed. This allowed Oleg to demonstrate how the software translates the data into relevant, useful information and was able to diagnose the cause of the fault.

This was a great opportunity for the trainees to view the practical applications of their training on the recloser device successfully operating in +42°C conditions.

NOJA Power is manufacturing low voltage switchgear for the Clem Jones Tunnel Project, one of Brisbane's most significant upgrades to its Transport Infrastructure, scheduled to be open in 2010.

Previously known as the North South Bypass Tunnel (NSBT), the Clem Jones Tunnel is the first section of the M7 motorway in Brisbane and provides a twin, 2-lane 6.8 kilometre link between Ipswich Road and the Pacific Motorway. Motorists travelling through the tunnel are expected to avoid 18 sets of traffic lights, reducing their travel time by 15 minutes and taking one-third off the peak traffic from the city's landmark Story Bridge.

The Tunnel will boast a variety of cutting edge, redundant electronic systems such as automatic traffic incident detection, ventilation control, air quality monitoring, CCTV monitoring, thermal detection and fire safety systems, directional signs, and an electronic tolling system providing national compatibility. All systems require high quality and reliable switchgear to provide for continual and uninterrupted operation.

NOJA Power Switchgear Pty Ltd has been commissioned to supply the Cross Passage Panels by United Group Infrastructure, a sub-contractor of the builders of the Clem Jones Tunnel - Leighton Contractors and Baulderstone Hornibrook/Bilfinger Berger Joint Venture (LBB JV).
