In order to realize the fast protection of MV(medium voltage) busbar, RTDS simulation test system is connected to the developed arc-flash protection device of MV busbar in accordance with operating parame-ters of field substation to establish the real-time closed-loop system for arc-flash protection of MV busbar. By setting different types of fault locations, various faults of MV busbar are simulated. The waves are recorded and action behavior of the protection is analyzed. The feasibility of arc-flash protection as fast protection of MV busbar is investigated, and the original intention of the design to meet the protection selectivity and sen-sitivity is verified.
