Abstract : We crossed all the experiments made over 15 years at ONERA during CNES R&D activities; we made hundreds of secondary arcing on Solar Panels or coupons, connectors, SADM1 or simple aged cracked wires. Thanks to the knowledge we have, from ESD2 or secondary arc triggering, to the analysis of in-flight anomalies; we deduct very simple design rules reducing drastically the probability of secondary arcing.Let’s follow the trail of the power line to find where there would be protection gaps.
