Field terminal unit design for 10kv power distribution grid fault processing system

摘要

The fault locating, insulating and resuming is the pivotal technology to power distribution net automation. Locating the fault interzone quickly and exactly is the precondition for insulating and resuming power supply. The reliability of fault locating automatic system relies on the performance of FTU. FTU has a strong anti-electromagnetic interference, temperature and other environmental adaptation. In case of loss of main power supply, the system switches to backup power supply in real-time, ensure the terminal operation reliably.
