Rogowski Coil solutions from Phoenix Contact provide a current transformer (CT) alternative that can measure alternating currents in eight ranges, from 0 to 100 amps to 0 to 4,000 amps. They are flexible, lightweight and can provide eight DIP switch-configurable CT ratios with one part number. The 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 bus bar mounting clamp and a simple bayonet latch on the coil housing. There are two available transducers that connect to the measurement coil. Customers have the option of a 0 to 1 amp CT output or a standard 0 to 10 volt/4-20 mA analog output. The outputs are universal and can be integrated with equipment from virtually any manufacturer. 800/322-3225; www.phoenixcontact.com.
