Abstract
An electrical isolation apparatus. A signal is transmitted between a first transmission circuit, a first reference circuit, a second transmission circuit, and a second reference circuit according to a principle of electric field coupling between conductors. Therefore, the electrical isolation apparatus can be applied to isolation and transmission for a signal with a relatively high frequency between a first signal device and a second signal device. In addition, a material used by the electrical isolation apparatus may be a common metal conductor, which greatly reduces a size and costs of the electrical isolation apparatus and facilitates manufacturing and implementation of the electrical isolation apparatus.
