- EdgeIQ Rogowski CT

EdgeIQ Director supports both Rogowski Coil and Camp-on CT for non-intrusive current measurement based on installation type. For pole-top transformer current measurement, the Rogowski Coil is recommended. For pad-mount transformer or indoor applications, the Camp-on CT is sufficient.
