Threshold IED67N.Sb \ Parameters.

A constant reset time can be set for each threshold (tED>RES, tED>>aRES, tED>>bRES, tED>>>RES,

tED67N.SbRES).

Shrink time

For each of the thresholds programmed with definite time characteristic, you can select contracted

time by setting to

the parameter

EnTcIED>def

EnTcIED>>adef

EnTcIED>>bdef

EnTcIED>>>def

and

EnTcIEDSbdef

, and regulating the contracted time (

tcIED>def

tcIED>>adef

tcIED>>bdef

tcIED>>>def

and

tcIEDSbdef

) and operating time (

tat-

cIED>def

tatcIED>>adef

tatcIED>>bdef

tatcIED>>>def

and

tatcIEDSbdef

Once the breaker closes, during the operating time (e.g.:

tatcIPE>def

), the value of the trip time

(e.g.:

tED>def

) is replaced by the contracted time (e.g.:

tcIED>def

); when the operating time

expires the trip time is reset (e.g.:

tED>def

Second harmonic restraint

For each threshold, a second harmonic restraint block can be set by setting to

the param-

eter

Functional block (Block3)

If the voltmetric measurement chain fails (function 74VT tripped) or amperometric measurement

chain fails (function 74CT tripped), all thresholds of protection 67N are blocked.

Ground directional overcurrent - 67N (Intermittent faults)

Preface

The maximum directional ground current protection function IED>>>> detects intermittent “Arcing

ground” faults

Detection is done by protection function 67N logically controlling the start statuses, by starting a

specific 59N threshold or by receiving the Goose IEC61850 for the state of start by residual overvolt-

age of the protection DV7500.

The logic of threshold IED>>>> is shown in the following figure:
