The 0.5% Accuracy Rogowski Coil by LEM is a flexible clip-around Rogowski coil for the electronic measurement of AC current with galvanic separation between the primary circuit (power) and the secondary circuit (measurement).
The patented Perfect Loop Technology dramatically reduces both the error due to the position of the measured conductor within the aperture, and the error due to the proximity of external conductors.
The LEM Rogowski coil is available in 4 sizes: ⌀70mm, ⌀125mm, ⌀175mm & ⌀300mm. It is lightweight and easy to install due to its thin coil design. The coil is 6.1mm thick and outputs 27 mV / 1000A at 60 Hz (22.5 mV / 1000A at 50 Hz).
