🔍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.

❓Frequently Asked Questions
What is a Rogowski coil used for?
It is primarily used for measuring and protecting three-phase current in power lines, especially high currents, pulse signals, and irregular conductor currents.
Do I need to disconnect the power for installation?
No, the split-core structure allows for quick installation and removal without disconnecting the primary cable.
What is the IP protection rating?
The product has an IP65 protection class, making it resistant to dust and low-pressure water jets.
Can it measure irregular shapes?
Yes, its flexible silicone rubber skeleton is designed specifically to wrap around conductors of large or irregular shapes.
What is the working temperature range?
The coil is designed to operate reliably within a temperature range of -40ºC to +70ºC.
Does the coil suffer from magnetic saturation?
No, Rogowski coils do not have a magnetic core, so they exhibit no hysteresis or magnetic saturation phenomena.
