Abstract: Abstract:The manual test and automatic test of the relay protection equipments were compared. The demand features for the automatic test system in development of recent intelligent relay protection equipments were analyzed. Based on this, a new comprehensive automatic testing scheme was proposed and realized. Using the new automatic test system, it is possible to realize comprehensive automatic test of the intelligent relay protection equipments. The use process of the automatic test system was expounded, and the design idea of the system in automation, visualization and intelligence was introduced in detail.
