The General Fault Criterion is an overall impedance measuring element with a very high reach and a long time delay for its tripping function.The GFC can be operated in two modes - the under impedance mode and the over current mode.In the under impedance mode, the GFC characteristic should, in general, cover all the impedance measuring zones used for distance protection, regardless of their directionality. Normally set to 2 times of zone-3 with a limit on the resistive direction so that the characteristics does not enter the load area.

PARAMETER SETTING

1. 1P-1P -> single-phase trip and reclosure for earth faults (single-phase dead time), no reclosure for phase faults

2. 1P-3P -> single-phase trip followed by three phase trip after approx. 20 ms, three-phase reclosure for earth faults (three-phase dead time initiated by single-phase trip), no reclosure for -phase faults

3. 1P3P-3P -> three-phase trip and reclosure for earth and phase faults (three-phase dead time)

4. 1P3P-1P3P -> single-phase trip and reclosure for earth faults (single-phase dead time), threephase trip and reclosure for phase faults (three-phase dead time)

5. Ext. Wahl -> External selection by the binary inputs MD1_EXT_1P_1P, MD1_EXT_1P_3P, MD1_EXT_1P3P_3P and MD1_EX_1P3P_1P3P.

Extension of 1st. dead time for single or three-phase reclosure (effective as long as a logical ‘1’ (pulse or continous) is applied to the ‘Extend t1’ I/P before the dead time finishes (falling edge.)

Period (CB recovery time) from the falling edge of the last reclosure attempt during which the autoreclosure function is blocked and after which the function is reset. In the event of an evolving fault between discrimination and dead times, the period commences at the instant of another trip occurring between the two times.The reclaim timer is also started if the protection trips after the fault duration time ‘t Oper’ has elapsed.

Period following the dead time during which the CB close signal has to occur. If it does not, the ‘Def. Trip’ signal is generated.

Time during which reclosure is blocked. ‘t AR Block’ is started by every blocking signal (‘Ext.Blk AR’, ‘Cond.Blk. AR’, ‘Manual Close’, ‘Inhibit Inp’ and ‘MasternoSucc’).

Instructions for Using the Setting Calculation Toolfor REL 5xx Numerical Line Protection Terminals

Always remember the following steps:

1. Open file by enabling macros. If by mistake you disabled the macros, reopen

the file by enabling macros..

2. This excel sheet is a read only file. Don’t remove the restriction, so that you

will not loose the original file

3. Once the data entry is over, use Save As command for saving your file.

4. In first sheet, choose the terminal (REL 511, REL 521 & REL 531), for

which setting calculation is to be done.

5. Fill in the blue coloured cells only.

6. Remember you are not allowed to put any data, in cells other than the blue

cells.

7. In first sheet (System Details) you have to Tick in cell B17, if the terminal is

REL 531 and is used for series compensated line.

8. User has to feed only “recomm_setting REL5..” sheet data into the relay.

Note: Suggestions on Improvement are Welcome. This excel sheet may contain

errors (may be zero errors). Request to report the errors to PTUA-RT.

THIS EXCEL SHEET IS INTENDED FOR INTERNAL USE OF ABB

PERSONALS.

This Setting Tool may change without prior notice. So its advised always use

latest Tool from PTUA-R database.
