Rogowski Coils (Flexible Rope CTs) with CTid

SKU: ERA-106-2775
$147.00

Details

Rope CTs are designed for 20-30 amps or greater load. Lower amperage results in lower accuracy readings.


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.
