In automotive industry, to deal with EMI problems, an efficient and proper screening attenuation measurement method is needed to make high performance and low cost shielded electrical wiring harness. Previously a screening attenuation measurement method titled PHSA (Power Harness screening attenuation) method [ 1 ] was proposed to measure screening attenuation in shielded power cable, which evaluates the shielding performance that prevents radiation from inner core to outside environment. The method was used to practically check the effects on performance of cable shield (shield effectiveness) due to different combinations of length and braid density against radiated noise. But the measurement time for actually performing experimental tests limits measurable combinations to evaluate the shielding performance of the wiring harness.
