On the side you can see a picture of the complete test set-up with the shielded power cables and the wooden stool for the measuring system, which is connected to the PC via optical fiber.
Prior to starting the test we determined the current levels needed to plot the attenuation graph:
I3=870 A value used for the final test.
The current values are checked with an ammeter clamp on one phase.
For each Mark we measured the induction at 3 different current values.
We repeated the measurements with the same parameters used in open space for each shielding configuration in order to compare the shielded induction values for each Mark.
The results of the tests show which shielding configurations are more efficient for a specific project.
Thus, the client can choose the solution that best fits his/her need.
It is obvious that other G-iron combinations could be designed upon request:
we could develop shielding solutions aimed to shield greater current levels or solutions aimed to reach the target level of induction at smaller distances from the source..
