Setting
Descriptions

Pickup Settings

Refer to

Table 3.2 on page 3.10

and

Table 3.3 on page 3.10

for the setting

labels. Use these settings to determine the level where the instantaneous
overcurrent elements assert and at what level the time-overcurrent elements
begin timing. The time-overcurrent element curves are scaled in multiples of
this pickup setting. Disable an element by setting the pickup to OFF and
disregard the other settings of the element.

Set the phase time-overcurrent element to provide sensitive detection and
coordinated time-overcurrent protection for balanced and unbalanced fault
conditions. Use the negative-sequence time-overcurrent element to provide
sensitive detection and coordinated time-overcurrent protection for
unbalanced fault conditions including phase-to-phase, phase-to-ground, and
phase-to-phase ground faults. Set the residual time-overcurrent element to
provide sensitive detection and coordinated time-overcurrent protection for
phase-to-ground faults.

Torque-Control Settings

Refer to

Table 3.3 on page 3.10

for the setting labels. Torque control refers to

a conditional enable of the element. Elements are torque controlled by setting
the Relay Word bit 51nTC to either one (permanently energized) or zero
(disabled) or by entering a SEL

OGIC

control equation. The latter provides

conditional assertion of the element as a function of the SEL

OGIC

control

equation.

Time-Dial Settings

Refer to

Table 3.3 on page 3.10

for the setting labels. Coordinate with

downstream devices by delaying the instantaneous pickup of an element using
this setting.

Curve Shape

Refer to

Table 3.3 on page 3.10

for the setting labels. Select curve shape and

time-dial settings to coordinate with downstream phase, negative-sequence,
and residual time-overcurrent elements. Refer to the time-overcurrent
equations and curves (see

Time–Overcurrent Curve Equations on page 3.16

)

for the specific time-overcurrent characteristic equations.
