1.Safety:The primary equipment is deeply integrated with the secondary equipment,to reduce the primary auxiliary equipment, without increasing the risk of failure;the linkage device is adopted to eliminate the potential safety hazards of accidental remote control caused by automation.

2.Effectiveness:Implement the selective tripping of short circuit faults(multi-level precise stage difference coordination):realize the selective automatic isolation of single-phase ground faults (transient fault location).

3.Advanced Nature:The product adopts the built-in ECT and EVT,and uses the capacitor power supply technology to solve the problem of terminal power supply.The shell utilizes the advanced manufacturing technique to achieve the protection grade of IP67. The partial discharge is not more than 20pC

4.Intelligentization:The terminal work is independent of the master station.It can rely on the machine learning and original algorithm to automatically diagnose the short circuit or single-phase ground fault and give action commands.

5.Usability:The operation is simple,with no need of changing operation habits,adding operating tools and steps,and accepting the professional training.The product can conduct the factory commissioning,and the modular replacement for maintenance,and support the hot swapping,greatly reducing the dependence on professional technicians.

6.Miniaturization:The primary equipment is deeply integrated with the secondary equipment (having the built-in ECT and EVT),and the weight is reduced by over 20kg,which lowers the on-site construction difficulty and improves the installation efficiency.
