Sectionalizer

sectionalizer objects provide a means to isolate faulted portions of a system. sectionalizer objects work in conjuction with the reliability module and the recloser objects. reliability will automatically open a sectionalizer if an upstream recloser is present, and has "tries" available. sectionalizer objects should work for both solver methods, but the reliability functionality only works in the NR solver.

A minimal sectionalizer implementation is:

object sectionalizer {
    name Test_Section;
    phases ABC;
    }

with an equivalent representation of:

object sectionalizer {
    name Test_Section;
    phases ABC;
    phase_A_state CLOSED;
    phase_B_state CLOSED;
    phase_C_state CLOSED;
    operating_mode BANKED;
    }

sectionalizer objects behave exactly like switch objects, aside from their reliability coordination. sectionalizer objects inherit all switch properties and default to a banked operation mode. No new parameters are introduced in sectionalizers.

Sectionalizer Parameters

Sectionalizer State of Development

sectionalizer objects are based on switch objects and share a common state of development. Normal operation is tested and verified. reliability-based actions are validated, but not fully tested at this time.
