PRODUCT OVERVIEW
TRKLS-R series split-core three-phase flexible Rogowski coils are mainly used for the measurement and protection of three-phase current in power lines. The output signal is the differential of the current against time, and through an integrator, the measured current can be truly restored. The coil has excellent transient response ability, no hysteresis and magnetic and saturation phenomenon, wide measurement range, high precision and wide frequency response range. The split-core structure, flexible silicone rubber quilt and skeleton, can be used to measure the current of conductors with large size or irregular shape. The coil requires very little installation space, light weight, simple and convenient installation, and no need to damage the conductor. It is widely used in the measurement of large currents where the traditional CT measuring current cannot be used normally.
