Which of the following current transformer types would be suitable for installation without removing the primary conductor?

The split core current transformer is designed specifically for applications where it is impractical to disconnect the primary conductor. Its installation process allows it to be opened and then clamped around the existing primary conductor without needing to remove it. This feature is particularly useful in retrofitting or maintaining existing electrical systems, as it minimizes downtime and simplifies the installation process.

While the Rogowski coil is also used for measuring alternating current and does not require the removal of the primary conductor, it is not classified as a traditional current transformer since it relies on the principle of inductive coupling rather than conventional core saturation.

The clamp-on current transformer also allows for non-intrusive measurements without disconnecting the primary conductor, but it typically refers to a more specific type of device that may not always match the performance characteristics or configurations of split core transformers.

Solid core current transformers, on the other hand, must be disconnected from the primary circuit to be installed, restricting their applicability in scenarios where removing the primary conductor is not feasible.
