Liquid-cooled drive
05 August, 2008 | Supplied by: Rockwell Automation AustraliaThe energy-efficient liquid cooling of the Allen-Bradley PowerFlex 700L drive allows it to be installed in conditions where air-cooled drives simply could not operate. These include dusty environments or those where increases in climate control costs would be excessive. Applications, which can benefit from this technology include HVAC and chillers, pumping applications, oil and gas, and marine propulsion.
Loy Yang Power drives long-term success
25 July, 2008Victoria’s largest energy producer, Loy Yang Power, recently embarked on an upgrade of its four-level open-cut coal mine facility, Loy Yang Mine. The ‘in progress’ upgrade includes the redesign and progressive changeover of the mine’s existing coal transfer conveyor drive systems. With a combined length in excess of 25 km, the mine’s conveying system transfers the freshly mined coal from the mine floor to the surface.

Output filter for motor drives
08 July, 2008 | Supplied by: Westek Electronics Pty LtdThe Schaffner Model 510 output filters reduce voltage slew rate (dV/dt) from inverter drives for variable-speed motors. High-voltage slew rates can cause overstressing of long motor drive cables and cause insulation breakdowns in motor windings.
Siemens SCADA software
08 July, 2008 | Supplied by: Siemens LtdSiemens has expanded the functionality of its SCADA system SIMATIC WinCC with version 7.0. The scalable SCADA system now offers compatibility with Windows Vista, easy language switching, high-performance analysis functions and an integrated MS SQL Server archive historian database as standard.
Quadraplex pump controller
08 July, 2008 | Supplied by: Dwyer Instruments (Aust) Pty LtdThe series QPC is used where four pumps are required to alternate to provide equal run time on each. Alternating loads allows for equal wear on all pumps, lengthening their operation life. The series QPC has five inputs allowing the four outputs to operate properly even if one of the inputs fails to open or close. Four LED indicators show the load that is energised by the SPST output contacts.
Chlorine controller
08 July, 2008 | Supplied by: Convergent Water Controls Pty LtdUnlike ORP control, using free or total chlorine control can give precise readings of the actual hypochlorous acid or free (residual) chlorine content of the water being treated. Hypochlorous acid content fluctuates with changes in pH and regular ORP readings can give false impressions of the actual ‘effective kill’ of the chemicals being used.
Proficy process control system
08 July, 2008 | Supplied by: GE Intelligent Platforms Asia Pacific Pte LtdProficy Process Systems Version 1.5 is a fully integrated process control system that is intended to provide customers with improved quality and reliability, increased throughput, performance and efficiency, and reduced total cost of ownership.
Premium platform for SolarGas
25 June, 2008 | Supplied by: Schneider ElectricEngineers and scientists around the world are looking for ways to harness the sun’s thermal energy to replace the diminishing global supplies of fossil fuel with a ‘clean’, carbon-neutral energy source. Australia is particularly well placed to do this, since it has the highest average amount of solar radiation per square metre per year on Earth.

Securing an integrated SCADA system
15 May, 2008 by Scott Wooldridge* | Supplied by: Schneider ElectricIn recent years, utility companies have undergone great changes in the way they run their businesses. The pressure to increase profits and reduce expenses has them integrating their SCADA systems with their business networks to streamline operations. The popularity of the internet has customers requesting online access to their accounts as well as online bill payment, further increasing network exposure. In addition, utility companies have reduced costs by leveraging the internet to facilitate core business operations such as outage management and procurement.
Analysing alarm and trend data: from insight to action
15 May, 2008 | Supplied by: Schneider ElectricIn the complex and demanding environment that most SCADA system users operate in, real insight comes from asking and answering the right questions.
