TRKLS-R series split-core three-phase flexible Rogowski coils are primarily engineered for the measurement and protection of three-phase current in power lines. The output signal represents the differential of the current against time, which, through an integrator, allows the measured current to be accurately restored.
The split-core structure, combined with a flexible silicone rubber quilt and skeleton, enables the measurement of conductors with large sizes or irregular shapes. Its lightweight design requires minimal installation space and eliminates the need to damage the conductor during setup.
