A Magnelab Rope CT comes in varying sizes with optional custom lead connectors. The flexible coil opens at the connector junction and may be installed on a bus bar or existing cable in a matter of seconds.

Other size coils may be purchased with an integrator as well. A strong pull is required, especially when the CT is brand new.

The removable section only fits one way, so as it is removed, notice how the steel core pieces fit together. When closing the CT, be sure to match up the ends the same way. If the CT seems to jam and does not close, the steel core pieces are probably not aligned correctly. Do Not Use Excessive Force! Instead, re-position or rock the removable portion until the CT closes without excessive force. After a CTS model split-core CT has been reassembled, a nylon cable tie may be secured around the perimeter of the CT to prevent accidental opening.

On CTBL bus bar models, reinstall the nylon screws and tighten them with your fingers. Do Not Use A Screwdriver! For best accuracy, these parts should not be interchanged with other CTs.

Solid-core CTs require that the phase conductor being measured be disconnected at one end so that it can be passed it through the opening in the CT. This is not difficult when the wire gauge is small but becomes impractical with larger wire gauges and multi parallel conductors. For correct measurements, CTs must be installed on the phase conductor that corresponds to the voltage input connection. The voltage input connections are on the green, five position, screw terminal block. It may help to use colored tape or labels to identify the wires.

To reduce magnetic interference between CTs on adjacent phases, it is a good practice to separate them by about 1 inch 25 mm. This also helps to prevent dust and debris from forming a bridge across the phase conductor terminals or bus bars and possibly causing a flashover arc. If the CT opening is much bigger than the conductor, position the conductor in the center in the CT opening.

Plastic cable ties can be used to secure the position of the CT on the phase conductor. Lower amperage results in lower accuracy readings. Face the arrow on the rope towards what you want to measure. Positive power polarity when power is against the arrow, and negative when it is the same direction the arrow points. The position of the Rope CT on the conductor affects accuracy.
