Bulk Current Injection (BCI) Test Setup
There are test standards for seperate industries, test setup is the same for the most part, difference will be the test levels and frequency range required. A ground reference plane shall be provided on the floor of the laboratory. The EUT shall be connected to the grounding system and arranged and connected according to its installation specific cations. A distance of 1 m minimum shall be provided between the EUT and any metallic structure. The discharge return cable of the test generator shall be connected to the ground reference plane, and this connection shall be of low impedance.
In cases where the length of the cable exceeds the length necessary to apply the discharges to the selected points, the excess length shall be placed non-inductively off the ground reference plane and shall not come closer than 0.2 m to other conductive parts in the test set-up.
Calibrating the system creates a drive file to ensure the test level remains consistent throughout the frequency band.
Make sure you are using a grounding plane to ensure reliable calibration.
To begin testing, ensure the test level file is accepted in the test sequence portion of the software. Remove the calibration flix, clamp the BCI probe around the lines, ensuring contact with the ground plane, while elevating your DUT and ancillary equipment with a non coductive material.
Note results could fluctuate quite a bit by simply by elevating the lines from the ground plane.
