INFORMATION

Description

The flexible current sensor can take alternating current measurements from any installation with a full rejection of DC components, a very low consumption of power, with no saturation problems, a low temperature dependence and a very good linearity. The flexible sensor has been designed according to the Rogowsky coil principle, measuring alternating current irrespective of the position of the conductor. The current conductor must not be near the coil cable joint, since the degree of error increases in this area. Its centred location also reduces the impact of external magnetic fields. Thanks to the flexibility of the current sensor, one or more conductors can be surrounded, regardless of their shape, to perform current measurement actions.

Applications

These flexible current sensors have been specially designed for the MYeBOX-150 and MYeBOX-1500 portable power analysers.
