High-accuracy sensors improve response, reduce costs for smart grid applications

S+C's IntelliRupter PulseCloser sensors respond to self-healing and protection applications for the smart grid with accuracy

03/29/2011


S+C Electric Company has 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 accuracy. 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.

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, according to S+C. 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 technology. With Pulseclosing, IntelliRupter reportedly improves power quality for businesses and consumers while dramatically reducing wear-and-tear on utility distribution system assets.
