Rope CTs (technically called Rogowski Coils) are large, flexible sensors for monitoring current like split-core CTs

  • Rope CTs are installed similar to standard split-core CTs, where a connector on the rope allows it to be opened and placed around a conductor without needing to thread the conductor through it
  • Rope CTs are excellent for bus-bars and large switch-gear applications that standard split-core CTs cannot fit around
  • Rope CTs are flexible and easy to install but require a minimum amperage of approximately 30A for accuracy
  • The CTid Rope CT is the same as the standard Rope CT but has a different style connector, contains CTid for auto-detection, and has an onboard LED that can be used to identify which CT is connected to a given sensor port, which can be useful if the CT leads cannot be traced from the meter to the conductors being monitored
  • 1x Rope CT with built-in 8 foot leads and 2-pin plug affixed
