Overview

The sectionalizer is applied in three phase power system with AC 50Hz and rated voltage 10-40.5kV. It is installed on distribution overhead line to isolate fault when corporate with recloser or circuit breaker. When fault occurs on the line, the faults current reaches or exceed preset threshold value, the sectionalizer can memorize the tripping times of upstream recloser. When it reaches preset times, it drops down to trip automatically.
Sectionaliser will drop down to trip automatically on the condition as given below:

First, the faults current exceeds presetting pickup current. Next, the counting time reaches presetting value (1, 2, 3 or 4). Third, the circuit loses voltage and the current is lower than 300mA. And then the Sectionlizer will trip automatically when the aforesaid conditions occur simultaneously. If any of aforesaid conditions doesn't occur, the Sectionlaizer will not trip automatically.

This sectionalizer uses micro-computer and operating trip mechanism and does not require external auxiliary supply.
