– Rigid: Solid core can be your solution but for the solid core, conductor must be inserted through window.
With the solid core, you must disconnect the conductor to feed it through the window opening of the DC CT.
– Compact and Light-weight: Split core can be your solution.
– When space is limited or the conductors’ shapes are odd, then Rogowski split core would be the solution.
Split core, and Rogowski coil CTs are designed to be easily installed without disconnecting any wires.
– What the meters require: With so meters many variables, it is sometimes difficult to choose exactly the right current transformers for a power monitoring project. Various meter models require checking and selecting the output and accuracy of the current transformers. Some ways meter choice impacts CT choice.
