Sectionalizer

The abb autolink sectionalizer is an isolating device that automatically isolates the faulted section of the overhead network when a permanent fault occurs.

Sectionalizer. Outdoor type sectionalizer with magnetic actuator operated mechanism with built in ct pt or current voltage sensors is suitable for structure as well as pole mounted execution for urban and rural electrification application. Eaton offers cooper power series recloser and regulator bypass switches and three phase overhead switches for general purpose distribution automation and distribution switching applications. The auto reclosers sectionalizers are used in the power distribution lines to enhance the reliability of the distribution system against the temporary or permanent faults.

If a temporary fault occurs the autolink allows the upstream recloser or breaker to clear the fault without interrupting the circuit. After a preselected number of recloser openings and while the recloser is open the sectionalizer opens and isolates the faulty section of line. This permits the recloser to close and re establish supplies to those areas free of faults.

Instead it counts the number of operations of the interrupting device upstream and opens while the interrupting device is open. By staying here you are agreeing to our use of cookies. We deal with pnc make auto reclosers and sectionalizers of 33kv and 11kv voltage level.

After a pre determined number of interruptions the sectionalizer will open thereby isolating the faulty section of the circuit allowing the recloser to restore supply to the other non fault sections. Autoself tm time voltage sectionalizer tvs is built of the ovx s high performance outdoor vacuum circuit breaker module and high speed tvx electronic sectionalizer module. The sectionalizer does not interrupt fault current.

Each sectionalizer detects and counts fault current interruptions by the recloser or circuit breaker. If the fault is temporary the operating mechanism of the sectionalizer is reset. The autoself functionality is built on a auto reclosing cycle count lockout function and simple time voltage logic including multiple timers.

Both autolink electronic sectionalizer and the. Auto recloser sectionalizer.
