Some aspects of bulk cable current injection (BCCI) test method at system level testing of an aircraft

The Bulk Cable Current Injection (BCCI) testing, at equipment/subsystems/system level has been recognised as a promising technique in lieu of radiated susceptibility testing upto few hundreds of MHz. Although it is an efficient technique for the evaluation of electromagnetic susceptibility (EMS) of the system, but at the same time due to its instrumentation particularly bulky and heavy current injection and monitoring probes, put a restriction to the use of BCCI, in the integrated system testing. In this paper, the use of BCCI test facility for integrated aircraft testing has been critically analysed and discussed. Problems which may arise due to the generation of strong harmonic products up to HF band in BCCI testing also have been discussed with their solutions.
