Matching a transformer to its anticipated load is a critical aspect of reducing energy consumption.
The VCPW-HD medium-voltage circuit breaker by Eaton are designed to protect transformers, capacitor banks, busbar sections, and cables.
Siemens produces an electrical distribution set of families to be AutoDesk Seek RMC Styleguide compliant
For loads up to 3,000 amps, the 00572TEC bypass/isolation switch from Russelectric reduces the unit’s footprint by 50% in comparison to side-by-side designs. The bypass/isolation switch allows the operator to bypass directly to either the normal or emergency source regardless of the position or condition of the transfer switch.
The advanced multi-criteria fire detector engineered by System Sensor combines a carbon monoxide sensing cell, an infrared sensor, a photoelectric smoke sensor, and a thermal sensor into one. If a fire condition is detected on one sensor, the unit confers with the other three before sending out an alarm. Advanced algorithms are then applied to interpret signals from each sensor to monitor every product of combustion while compensating for changing conditions. www.systemsensor.com #8.
The Council of American Mechanical/Electrical Engineers, a coalition of members within the American Council of Engineering Companies, is planning several events in conjunction with the ASHRAE Summer Meeting in June in Salt Lake City.
The Tempstar product line from International Comfort Products includes 25-ton PGE300 package gas/electrics with up to 9.5 EER efficiency. This two-stage rooftop unit uses R-22 refrigerant with multiple hermetic-type scroll compressors. The ASHRAE 90.1-compliant unit features independent cooling circuits to provide part-load cooling operation.
The term smart materials refers to an interesting class of materials that are able to respond dynamically to external stimuli like heat, humidity, ultraviolet light and pressure. Smart materials systems have sensing and actuating functions that are used for an increasing number of engineering and commercial applications. Currently, the application of smart materials spans most industrial sectors including electronics, medical diagnostics, treatment and surgery, automotive and industrial research processes that require control and sensing. According to a soon-to-be-released and updated technical market research report, RGB -154N Smart Materials: A Technology and Market Assessment from business communications co., inc. (www.bccresearch.com) , the worldwide smart materials market is estimated at $8.1 billion in 2005 and is expected to rise at an average annual growth rate (AAGR) of 8.6% to $12.3 billion in 2010.
