| Abstract: | We devise a power protection system for LV busbar with an idea of distributed design employ instantaneous three-point interpolation to communication media, which increase the detection identify speed current mutation with CAN bus for short circuit fault. This system We as hashigher sensibility and better interference suppression capability. |
