&C’s IntelliRupter PulseCloser is a breakthrough in overhead distribution system protection. It’s a unique alternative to conventional automatic circuit reclosers. IntelliRupter was designed from the ground up to accommodate advanced distribution automation functions, including S&C’s self-healing, scalable IntelliTEAM SG™ Automatic Restoration System — a universal Smart Grid solution offering unmatched interoperability. IntelliRupter provides SCADA functionality too. IntelliRupter offers significant benefits for radial line protection. And it provides better segmentation and coordination than conventional reclosers in non-communicating loop restoration applications.
After clearing a fault, a conventional recloser tests the line through uncontrolled closing — repeatedly applying damaging fault current to equipment from the source to the fault. But IntelliRupter utilizes S&C’s revolutionary PulseClosing™ Technology — a unique means for verifying that the line is clear of faults before initiating a close operation. Pulseclosing greatly reduces stress on system components, as well as voltage sags experienced by customers upstream of the fault.
IntelliRupter includes a base-integrated control that’s accessed for configuration and operation via a secure WiFi link. This innovative approach improves reliability, operator safety, and convenience, and significantly enhances security compared to the “lock-and-key” approach of most conventional reclosers.
