Rogowski Coil solutions from Phoenix Contact provide a current-transformer alternative that can measure alternating currents in eight ranges, from 0 to 100 to 0 to 4,000 amps. Unlike traditional split-core CTs, they are flexible, lightweight, and can provide eight DIP switch-configurable CT ratios with just one part number. The Rogowski principle of operation eliminates dangerous open-circuit voltages and the need for CT shorting blocks. The measurement coil is designed as an open-ended loop, allowing the coil to be installed quickly on an existing conductor. There are no tools to handle and no hardware to lose, thanks to a busbar mounting clamp and a simple bayonet latch on the coil housing. There are two available transducers that connect to the measurement coil — a 0-1 amps CT output or a standard 0-10-volts 4-20mA analog output. The outputs are universal and can be integrated with equipment from virtually any manufacturer. 800/322-3225; www.phoenixcontact.com
