Continental Control Systems
Continental Control Systems has introduced the CTRC Rogowski coil current transformer. The device is designed to simplify installations to meet the increasing demand for accurate current measurement on conductors where traditional split-core and solid-core CTs are difficult to use. With its flexible design, the CTRC is ideal for large bus bars and irregular-shaped conductor bundles. The new coil offers a small, flexible profile, enabling it to be used on conductors in tight spaces where rigid CTs won't fit.
Available for single and three-phase services, the output of the CTRC's flexible coil is connected to a conditioning circuit, where it is converted to a low-voltage 333.33 mVac signal compatible with any WattNode® meter for accurate energy (kWh) and power (kW) production and consumption measurements. The UL-recognized CTRC provides accuracy of ±1% from 5% to 120% of rated current for loads up to 6000 amps. The Rogowski coil is offered in four standard diameters from 3.1-in round (loads to 400 amps) to 12-in round (loads to 4000 amps). Non-standard size and load configurations are available upon request.
