For the calculation, the immersion depth is defined via the radius. As such, the smaller the radius, the greater the field strength. It is therefore advisable to mount the sensor as closely as possible on the down conductor, so that the effective field strength is as great as possible.
H = Field strength [A/m]
r = Radius [cm]
I = Current [A]
The radius is the measurement for the immersion depth of the sensor in the magnetic field and for recording the effective magnetic field strength H there. The value corresponds to the distance from the center line of the conductor to the outer edge of the sensor housing.
The radius is determined during installation. This is important for the calibration of the system, as it ensures the same measurement conditions for different system conditions.
