Abstract Low voltage direct current (LVDC) distribution systems have great potential application in conventional areas, such as residential buildings, and the promotion of LVDC is constrained by the lack of appropriate protection and security guarantees. Compared with traditional AC system, DC systems face more challenges, but related reviews are rare at present. This paper conducts a comprehensive overview regarding questions in electrical safety of LVDC distribution system, including protection scheme, short current calculation, dc arc extinction, capacitor discharge, protection against electric shock, terminal over-current protection, and special requirement of load protection from the civil point of view. The issues needed more research works and discussions are also presented.

Key words： Low voltage direct current distribution system protection electrical safety protection against electric shock short circuit
