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.
IS THERE A DIFFERENCE BETWEEN BULK CABLE INJECTION AND BULK CURRENT INJECTION?
No. The difference is based on how a test standard refers to the test. MIL-STD-461 CS14 refers to the test as a bulk cable injection test where as commercial, industrial, and automotive standards will refer to the test as current injection.
BCI EMC TEST STANDARDS
BULK CURRENT INJECTION SYSTEM CALIBRATION
Calibrating the system creates a drive file to ensure the test level remains consistent throughout the frequency band. The file will be automotically populated in the test portion of the software for immediate use, these can be recalled at a later time as well.
Make sure you are using a grounding plane and everything is adequately grounded to ensure reliable calibration.
BCI SYSTEM CALIBRATION
Leveling a test system with Helia software for bulk current injection testing according to ISO 11452-4
BULK CURRENT INJECTION TESTING
To begin testing, ensure all hardware is properly grounded and 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.
