Rogowski coil Current sensors_ARCT-D series - 1

ARCT-XXX-D SERIES The flexible Rogowski coil of the high-accuracy split-core current transformers offer significant installation advantages over the general split-core CT's because of their light weight, wide current(10-5000+ Amps), mechanical flexibility for mounting in tight quarters and easy placement around cable bundles or large busbars. Offered in 80, 115, 180, and 300 mm window sizes, the ARCT-D series is the most accurate Rogowski coil in submetering. Applications ■ Power quality monitoring & control systems ■ Harmonics and transients monitoring ■ DC ripple measurement ■ Measuring devices, lab instrumentation Standards ■ UL/EN 61010-1, Third Edition, May 11,2012, Revised April 29 2016 ■ CAN/CSA-C22.2 No. 61010-1-12,3rd Edition, Revision dated April 29 2016 ■ IEC 61010-2-032:2012(3rd Edition), UL/EN 61010-2-032 (IEC 61010-2-032:2012) ■ EN61010-031, EN61010-2-031 E344623 V.
