ARCT-XXX-M-ID

Flexible Rogowski Coil CT with Embedded CTid for High-Current AC Monitoring

The ARCT-XXX-M-ID Series from hqsensing is a high-flexibility Rogowski coil current transformer designed for accurate AC current measurement in large-scale applications. This split-core, non-intrusive sensor offers galvanic isolation between the primary and secondary circuits and is optimized for use with SENSWAY meters equipped with embedded CTid.

Engineered for installations where traditional split-core CTs are impractical such as busbars and large switchgear the ARCT-M-ID provides a reliable solution for monitoring medium to high currents. While offering the flexibility and convenience typical of Rogowski coils, it delivers optimal accuracy at current levels above approximately 30A.

Certified to IEC 61869-2 Class 1.0 and IEEE/ANSI C57.13 Class 1.2, each unit undergoes strict testing for ratio error and phase displacement. The integrated CTid chip enables automated identification by compatible meters, while the built-in LED indicator helps locate the CT’s position ideal when cables are routed through dense panels or hard-to-trace paths.
