The double insulation topic has become a very important issue in the satellite design since its implementation drives the sizing of the whole satellite electrical architecture. Different approaches and solutions have been proposed by Industry [2], according to specific need of each spacecraft design and requirements. According to ECSS-E-ST-20C [1]., a barrier against short circuit between conductors or circuit elements shall be guaranteed also after any credible single failure. In particular., the guideline is that all non-protected elements of a main bus distribution system shall implement an electrical double insulation up to the first protection device (e.g.: fuse., current breaker or current limiter).
