4000 A Rogowski Coil with /5A Output, 150 mm Diameter, 2 Meter Cable

The flexible Rogowski coil current sensor is used to measure alternating current (AC), especially at high currents. Thanks to its flexibility, it can be used to measure current in conductors with large diameters, irregular shapes, or in tight spaces between conductors (for example, when a traditional current clamp or current transformer cannot measure, the flexible Rogowski coil provides a convenient solution).
Rogowski coils are known for their inherent advantages, including high linearity, a wide frequency range, and immunity to magnetic saturation.
The non-invasive design ensures easy installation without requiring direct electrical contact or modification of the primary circuit.

Installation Guide

1. Switch off all power sources to this device and the equipment in which it is installed before performing any work.
2. Always use a suitable and approved voltage measuring device to confirm that all power is off.
3. Turn the gray locking sleeve counterclockwise to disconnect the connector. Open the coil.
4. Place the Rogowski coil around the conductor and bring the ends together.
5. Reinsert the connector into the coupling and turn the sleeve clockwise until securely fastened.
6. Connect the signal outputs to your integrator, oscilloscope, measuring instrument, or power analyzer to start real-time current measurements.
7. Restore power to the panel.

Important: Secondary sides of current transformers must always be short-circuited or connected to a burden.
