RT 500

Flexible split-core Rogowski coil for the electronic measurement

of AC waveform currents, with galvanic separation between the

primary circuit (power) and the secondary circuit (measurement).

The patented Perfect Loop Technology definitely solves the problem

of the Rogowski coil opening by introducing a specific magnetic

device. This dramatically reduces both the error due to the position of

the measured conductor within the sensor, and the error due to the

proximity of external conductors.

Notes: 1) LEM provides uncalibrated coils with up to 5 % manufacturing tolerance.

Calibration must be performed within the final application.

2)

Open circuit condition (no load).

3)

Considering a primary conductor of at least Ø 15 mm perpendicular to

the RT loop.
