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 the advantage of the split-core design?
The split-core structure allows for quick and easy installation or removal without disconnecting the primary cable, ensuring safe and efficient current testing.
Does the Rogowski coil experience magnetic saturation?
No, because it has no magnetic core, it is free from hysteresis and magnetic saturation, allowing for a very wide measurement range and high linearity.
What is the protection rating of this product?
The TRKLS-R series has an IP65 protection class, making it suitable for various indoor environments with high durability.
Can it measure irregular conductor shapes?
Yes, the flexible silicone rubber skeleton and quilt allow the coil to be used on conductors with large sizes or irregular shapes where traditional CTs cannot be used.
What is the operating temperature range?
The product is designed to operate reliably in temperatures ranging from -40ºC to +70ºC.
What kind of output terminal does it use?
The secondary output typically adopts an RJ45 crystal terminal network cable, and the length can be customized based on specific requirements.
