In the operation of the electrical automation system, the application of the zero-sequence current transformer has played a good role in protecting equipment and systems, effectively reducing the incidence of power system failures and ensuring that it plays a protective role without malfunctioning.
The zero-sequence current transformer has good fault judgment ability. When a fault occurs, it can find the fault in a very short period of time, make judgments on the fault point, and issue an alarm, so that the maintenance personnel rush to the scene to eliminate the fault in time.
When the distribution network is in a high-efficiency operation state, the application of zero-sequence current transformers has good flexibility, and can also make judgments on very small faults, accurate fault occurrence scope, fault type and fault time, etc. reduce the loss caused by failure.
