With the benefit of a 20-year operating life and the highest inverter reliability in the industry, this megawatt-scale power plant offers the reliability and redundancy needed to ensure uptime in large solar power systems.

As with PV Powered’s standalone 260kW commercial inverters, the PowerVault has a standard 295VDC minimum MPPT and an optional full-power 265VDC minimum MPPT- the lowest MPPT voltage of any commercial inverter in the industry. This makes the PowerVault ideal for use in the North American market and for getting the most power out of the new lower-cost thin-film solar arrays.

“The PowerVault provides a new level of efficiency and reliability for utility-scale solar power applications,” said Gregg Patterson, PV Powered CEO. “But what is really attractive to large solar installations are the financial benefits they can get by using a factory integrated, tested and configurable solution that eliminates significant field labor costs,” added Patterson.

With first customer shipments being made this quarter, the PowerVault platform is backed by an industry leading 10-year nationwide warranty and an unprecedented optional 20-year warranty.

Transformer Winding Hotspot temperature is a critical parameter required to manage the loading, life and reliability of transformers. Common devices, such as winding temperature indicators (WTIs) or electronic temperature monitors (ETMs), try to simulate or calculate this temperature. The only true measurement of this parameter is obtained using fiber optics sensors fitted directly into the transformer’s windings.

The LumaSMART builds on the ruggedness, reliability and stability pioneered by its predecessor products such as the WTS-22 and ThermAsset2. The LumaSMART is the industry’s first smart grid ready winding temperature hotspot monitor.

For the operator, the touch screen display on the LumaSMART offers users easy-to-use trending tools, graphics and alarm configurability necessary to customize the LumaSMART product to exactly fit their needs. In addition, enlarged on-board data storage allows 1 GB of historical data for analysis by the user.

The LumaSMART allows a range of connectivity options, including RS232, RS485, TCP/IP and USB along with numerous protocols, significantly simplifying integration with any SCADA or DCS package in substations. For the transformer manufacturer, it is compact, easy to install and configure. The LumaSMART is expandable to configurations allowing up to 16 measurement points and 16 programmable relays.

“The Winding Hot Spot Temperature is the single most critical parameter to monitor on your transformer. Using Luxtron’s patented Fluoroptic Technology, LumaSMART offers the most flexible platform in the market to perform direct, real-time winding hot spot measurements,” comments Brett Sargent, Global Vice President of Sales for LumaSense Technologies. “The winding hot spot directly relates to transformer life, loading capacity of a transformer and predictive maintenance practices for the transformer. Customers need the best technology to accurately measure this critical parameter and the LumaSMART offers this. It allow users to easily integrate critical information into their automated data and control systems.”

Developed for optimum engine protection in natural gas engines, Mobil SHC Pegasus Series exhibited an impressive average energy savings of up to 1.5 per cent1 in independent university laboratory testing and statistically validated field tests.

The energy savings will also translate into an equivalent reduction in carbon dioxide emissions from gas engines operating with these oils.

As a result of extensive laboratory and engine research, as well as comprehensive in-house testing, the new Mobil SHC Pegasus formulation delivers the potential for reduced fuel consumption, increased oil drain intervals and exceptional engine cleanliness and component protection.

Controlled field testing in demanding gas compression applications has shown that Mobil SHC Pegasus drain intervals can exceed 12 000 hours, or three to four times that of standard natural gas engine oils. Extending oil drain intervals can help reduce the amount of downtime the engine experiences, as well as reducing the amount of waste oil generated.

These excellent performance characteristics help foster an immediate improvement to companies’ bottom line through increased engine reliability, extended oil life-time, reduced maintenance costs and lower fuel costs. This has been achieved by developing the first advanced gas engine oil formulation that delivers real energy saving potential but not at the expense of component life. “Building on our experience in supplying the highest levels of lubrication protection and reliability in gas engines, Mobil SHC Pegasus provides an energy saving performance which is unattainable with conventional lubricants,” said Michael J. Hawkins, ExxonMobil’s global Mobil SHC brand manager.

“In an industry where energy costs represent a significant percentage of operating costs, emissions regulations are becoming more stringent, and engine reliability is so critical to productivity, this new series is yet further proof of ExxonMobil’s understanding of its customers’ needs and our commitment to helping them achieve increased efficiencies and reduced emissions without sacrificing the technology-leading performance of our lubricants.”

This latest addition to ExxonMobil’s flagship brand of high-performance gas engine lubricants will be introduced worldwide in 2010.

1.Efficiency measurements relates solely to the fluid performance when compared to ExxonMobil standard SAE 40 natural gas engine oils. Efficiency improvements may vary based on engine make/model and specific engine operating conditions. The energy efficiency claim for this product is based on test results on the use of the fluid in accordance with all applicable industry standards and protocols.

Previously the preserve of government establishments, the Roke High Voltage Facility will offer an additional option to organizations involved in the development of future sources of power or tests for high energy physics that require advanced accelerator technology.

The UK government is currently funding academic organizations to investigate the concept of Accelerator Driven Subcritical Reactor (ADS) systems to provide an alternative carbon-free power source of the future.

The accelerator itself is vital to the operation of such a reactor and will require significant investment to ensure a high enough performance and reliability.

Advanced accelerator sub-systems can be developed and tested at Roke’s new facility.

The Roke High Voltage Facility can accommodate Radio Frequency (RF) power and voltage on a massive scale. It combines high voltage isolation with screening to 18 GHz, whereby most other facilities only allow for testing at 50 Hz or at low voltage. The new service will offer an additional option to both public and private sector organizations that wish to test and commission high voltage and high power RF equipment such as accelerator components, ultra high power RF amplifiers, associated transmission lines plus electrostatic systems.

Alastair Cook, industrial and medical business sector manager at Roke, said: “A major issue for organizations wanting to test high power and high voltage systems is the availability of facilities and management of the hazards. This presents a serious dichotomy for organizations that want to accelerate time to market for their products, but also need to conduct complex and often hazardous tests first.

Our new High Voltage Facility represents the largest single investment Roke has made in testing for a number of years and we hope that organizations across the world will recognize the benefit of this unique and easy to access resource,” concluded Cook.

The HV facility has two screened chambers, one for the equipment under test and a second to hold test equipment and power supplies. Control is performed from a remotely operated and isolated console from which tests can be controlled and progress viewed via a high resolution camera link and optically isolated test gear.

The primary test chamber is 4.8m x 4.5m x 4.5m in volume and has double door access that can allow heavy structures to be manoeuvred into position.

To complement the facility there is a team of trained and competent personnel to help customers using the service, along with a robust set of procedures to enable a safe operating environment.
