Current Transformers
ARCT-XXX-M-ID
The ARCT-M-ID series features Rogowski coil split-core current transformers designed for the electronic measurement of AC waveform currents, ensuring galvanic isolation between primary and secondary circuits. Specifically tailored for SENSWAY IoT meters with embedded CTid, these transformers undergo rigorous testing for ratio error and phase shift, meeting the accuracy standards of IEC 61869-2 Class 1.0 and IEEE/ANSI C57.13 Class 1.2."
The ARCT-M-ID Series is a large, flexible sensor ideal for monitoring currents akin to split-core CTs. It is particularly suitable for busbar and substantial switchgear applications where standard split-core CTs aren't fitting. While Rogowski coil CTs offer flexibility and ease of installation, they demand a minimum current of approximately 30A to maintain accuracy.
The CTid ARCT-M-ID Series is analogous to the standard Rogowski coil CT but showcases a distinct connector style, incorporates a CTid for automated detection, and comes equipped with an onboard LED. This LED becomes invaluable in identifying the CT connected to a specific sensor port, especially when the CT lead is untraceable from the meter to the conductor in question.
