There are several different models of current sensors in various window sizes, split-core, flexible Rogowski coil, amperage ranges, and accuracy grades.
To choose a current sensors, it is better to first determine the model you need based on the maximum load current you are measuring and the size of the conductor you are measuring, and then choose.
– Split Core: Compact & light-weight line hinge design
– Air core; Rogowski Coil:
When space is limited or the conductors’ shapes are odd, then Rogowski split core would be the solution.
–> Split core, and Rogowski coil current sensors are designed to be easily installed without disconnecting any wires.
With so meters many variables, it is sometimes difficult to choose exactly the right current sensors for a low voltage transformer monitoring project. Various meter models require checking and selecting the output and accuracy of the current sensors. Some ways meter choice impacts CT choice:
