S&C's IntelliRupter® High-Accuracy Sensors Improve Response, Reduce Costs for Smart Grid Applications

CHICAGO, March 28, 2011 /PRNewswire/ -- S&C Electric Company, a smart grid leader shaping the future of reliable electric power delivery, today announced that its IntelliRupter® PulseCloser now offers high-accuracy voltage and current sensors.

These sensors enable the IntelliRupter to respond to self-healing and protection applications for the smart grid with greater accuracy than any device currently on the market. The sensors also offer a cost-efficient approach to capturing the high-accuracy current and voltage data needed to support other smart grid applications such as volt/var control and circuit optimization.

"Accurate sensing systems capture the data that intelligent grid networks need to support a multitude of smart grid applications," said Michael Edmonds, S&C's Global Smart Grid Strategies Director. "The IntelliRupter's built-in sensors obtain crucial operational data and eliminate the need for utilities to install separate sensing devices, reduce installation and maintenance costs and improve the return on their IntelliRupter investment."

IntelliRupter's sensors provide a steady-state system sensing accuracy of 0.5 percent across both the voltage and current sensing operating ranges. With this improved accuracy, IntelliRupter offers one of the most accurate sensing systems available for utility distribution systems. High accuracy is essential to ensure proper performance of many smart grid applications, such as advanced overcurrent protection.

S&C also announced that 15-kV IntelliRupter models now feature a standard 16-kA interrupting rating, broadening the range of applications that can benefit from IntelliRupter's breakthrough Pulseclosing(TM) technology. With Pulseclosing, IntelliRupter improves power quality for businesses and consumers while dramatically reducing wear-and-tear on utility distribution system assets.
