Product Overview

TRKLS-R series split-core three-phase flexible Rogowski coils are engineered for high-precision measurement and protection of three-phase current in power lines. The output signal is a differential of current against time, which, when used with an integrator, accurately restores the measured current. These coils feature excellent transient response, zero hysteresis, and no magnetic saturation.

Frequently Asked Questions

What is the main advantage of a flexible Rogowski coil over a traditional CT?
The flexible Rogowski coil has no magnetic core, meaning it cannot saturate. This allows for a much wider measurement range, better transient response, and the ability to fit around large or irregular conductors.
Does this coil require an external power supply?
If used with an integrator to convert the differential signal into a standard current or voltage output, a 5~15VDC power supply is typically required for the integrator component.
Is the installation process complex?
No, the split-core design allows you to wrap the coil around a conductor and lock it in place without having to disconnect the primary circuit.
What is the environmental protection rating?
This model is rated IP65, making it highly resistant to dust and low-pressure water jets, suitable for various indoor and protected outdoor environments.
Can the output cable be customized?
Yes, the secondary lead uses a shielded wire or RJ45 terminal, and the length can be customized according to specific on-site requirements.
