Repeater Enhances Smart Grid Mesh Radio Networks

Cooper Power Systems has introduced the EH Repeater for enhancing Smart Grid mesh radio networks. This is one of several products that use Cooper’s proprietary EH Power Supply technology, a family of energy-harvesting products that can be used to power a variety of radios and sensors.

The Repeater integrates Cooper Power’s EH Power Supply and a radio into one integrated unit designed to improve a utility’s radio coverage, mesh-network density and communications reliability. The repeater can be installed in less than 20 minutes with the use of a hot stick or glove and without the constraint of a 120-240VAC power source. The Repeater’s integrated design harvests energy from the electromagnetic field around existing power conductors, eliminating the need for secondary power sources and their associated spare parts inventories. An additional benefit is minimizing additional training for installation personnel, since the repeater design is based on well established electric utility Faulted Circuit Indicator technology.
