Phase operation
In Three-Phase Trip, Three-Phase Lockout (ganged) mode, all
three phases simultaneously trip and close.
In Single-Phase Trip, Three-Phase Lockout and Single-Phase
Trip, Single-Phase Lockout modes, each phase operates
independently with protection parameters the same for all
three phases.
In Single-Phase Trip, Three-Phase Lockout mode, all three
phases trip to lockout when one phase sequences to
lockout.
In Single-Phase Trip, Single-Phase Lockout mode, each
phase independently sequences to lockout.
Ground operation
In Three-Phase Trip, Three-Phase Lockout (ganged) mode, all
three phases trip and close.
In Single-Phase Trip, Three-Phase Lockout and Single-Phase
Trip, Single-Phase Lockout modes, ground tripping is active
when all three phases are closed. Ground trip is disabled
during the reclose interval of any one phase.
For faults above the ground minimum trip value, and below
the phase minimum trip value, all three phases trip on
ground and advance to the next sequence position.
For faults above the phase and ground minimum trip value,
the control trips on the phase(s) above phase minimum trip,
operating on the phase or ground TCC, whichever is faster.
Only tripped phases advance in sequence and are counted
as phase operations.
Phase/ground sequencing
Phase and ground share the same sequence position.
Asthe position sequence advances, the phase and ground
TCCs advance together to maintain proper coordination with
upline and downline devices. This is applicable for temporary
and permanent faults including faults on multiple phases.
