PREFACE
Scope
This manual describes the functions and features of the REL300 Relay System. It is intended primarily for use
by engineers and technicians involved in the installation, testing, operation and maintenance of the REL300 sys-
tem.
Equipment Identification
The REL300 equipment is identified by the Catalog Number on the REL300 chassis nameplate. The Catalog
Number can be decoded by using Catalog Number Table 3-1 on page 3-51 of section 3.
Production Changes
When engineering and production changes are made to the REL300 equipment, a revision notation (SUB #) is
reflected on the appropriate schematic diagram, and associated parts information. Refer to I.L. 40-385.11 for
current sub number information.
Equipment Repair
Repair work is done most satisfactorily at the factory. When returning equipment, carefully pack modules and
other units, etc. All equipment should be returned in the original packing containers if possible. Any damage due
to improperly packed items will be charged to the customer.
Document Overview
The circuitry is divided into 6 standard modules and one option module. Section 1 provides the Product Descrip-
tion, which includes software functions. Section 2 presents the Specifications. Section 3 presents Pilot and Non-
Pilot applications with related Catalog Numbers for ordering purposes. REL300 Installation, Operation and
Maintenance are described in Section 4, with related Setting Calculations in Section 5. Acceptance Tests for
both Non-Pilot and Pilot System are described in Appendix A & B . The Index shows Index to Nomenclature.
System Diagrams are included in the Diagrams section at the back of the book.

Setting Nomenclature Appliques
If this I.L. is included as part of the shipment of an REL300 Relay system, the I.L. will contain setting nomencla-
ture appliques which can be placed in a convenient location, e.g., inside the two FT-14 covers. The appliques
provide a convenient (and complete) set of REL300 “settings” (see Table 4-1 on page 4-16 of section 4 for set-
ting nomenclature). There are two appliques which are printed protective sheets (contained in a plastic enve-
lope); the back of the sheets can be removed thereby exposing a stick-on surface.

Features Included in Version V2.71
The following features are standard for the Pilot REL300 V2.71:
Features Included in Version V2.71
The following features are optional for the Non-Pilot and the Pilot REL300 V2.71
1. Changed 3V0 from 3 volt to 1 volt for the direc-
tional units in order to increase the sensitivity for
Zone-2 and Zone 3 applications.
2. Changed the FDOG pickup angles, 3I0 leading
3V0 between 75 and 255 degrees to overcome
the phase shift due to the connection of ground
resistors.
3. Changed the RDOG timer from 16/0 to 33/0 ms.
For a 3-phase fault at 0% location, the RDOG
may pickup momentarily and may start the TBM
(Carrier keying); therefore, it may delay the pilot
trip action.
NOTE: for the pilot application, the setting of
FDGT must be equal to or greater than 3 cycles.
4. Changed the LOIB timer from 0.5/0.5 to 10/0.5
seconds in order to prevent the block of Z2G,
Z3G and GB tripping if the settings of T2G and/or
T3G are greater than 0.5 seconds.
5. Changed the LOPB logic by removing the lead
between LOP (8/0) and AND1G.
6. Corrected the angle display for the 1-amp ct ap-
plication. Now, the angle display is extended from
50% to 10% of the ct rating.
7. Removed the GS control function and remove
LOP and LOI from Alarm-1. Reassigned the GS
contact as LOP or LOI alarm (AL-3).
8. Extended the setting range of XPUD from 0.300 -
1.500 to 0.050 - 1.500 settings.
9. Reduced the pickup and dropout timing errors of
the PCO-4 and PCO-8 timers and limited the tol-
erance within 1 cycle of the setting values.

Please refer to system drawing 2865F41 Sub 2, in I.L. 40-385.4 and drawing 2693F60 in I.L. 40-385.6 for the
following changes.
1. GENERAL APPLICATION UPGRADES
a) CIF trip logic – Added a timer 200/0 between OR222A and AND22 by changing the setting of CIF se-
lection, e.g., the CIF trip with or without the timer is now determined by user. Refer to section 3.4.7 for
the new settings and application.
b) Added an adjustable T1 timer from 0 to 15 cycles in one-cycle steps.
c) Changed the setting ranges of PANG and GANG from 40-90 to 0-90 degrees and ZR setting from 0.1-
7.0 to 0.1-10.0 for underground cable application.
d) Changed LOPB setting from NO/YES to NO/DIST/ALL, i.e., added a setting “ALL” to block trip for LOP
condition. The setting of LOPB=DIST is equivalent to “YES”, i.e., block the distance units only.
e) Added PTRI setting (YES/NO) to control the pilot reclose.
f) Added an OR62E gate between the signal T1RI and switch Z1RI for Zone-1 and IT reclose. The
OR62E has three inputs – ITP, ITG and T1RI.
g) Correct the GB trip target error if the input trip currents are removed instantly after the closure of the
trip contacts.
h) Improved Phase Selector for single-pole trip with load current condition.
i) Added NOT logic selection in programmable contact outputs.
j) Desensitized FDOG and RDOG from 3V0 > 1 volt to 3V0 > 3 volts.
k) Can use the pre-fault phase voltages (FDOP) to supervise the Zone-1 and pilot trip for 3-phase fault
condition.
2. POTT SYSTEM IMPROVEMENTS
a) Added a path and an inverter between the output of OR16 and the input of AND45A. Removed the path
between the TBM timer (0/50) and AND45, and added a path and inverter between the TBM timer &
AND34. The TBM is now reset after the PLTG or PLTP picks up for three cycles.
b) Added a path from AND30A (PILOT) to the input of AND65A, i.e., the weakfeed application is for POTT
scheme only.
c) Changed the input of AND49A and AND49E from TRSL to TRSLA (TRSLB or TRSLC for single-pole
trip and keying application).
3. BLOCKING SYSTEM APPLICATIONS
a) Carrier keying logic was modified to speed up resetting TBM for certain types of evolving faults by
changing the input of AND24 from HST to TRSLA/TRSLB/TRSLC.
4. SINGLE-POLE TRIP LOGIC
a) Changed the faulty phase voltage from 0 to the pre-fault voltage after the single-pole trips.
b) Added a negated X2 to disable the LOIB logic and allows the 62T trip under the pole disagreement
condition.
5. SELF-CHECK
a) A self-test was added to indicate the opto-input status in the test mode.
Significant Changes to Version V2.70 (from V2.10)
(For customers who are familiar with Version 2.00 and beyond)

IMPORTANT APPLICATION NOTES
1. PILOT SYSTEM
a) The setting of Z3FR must be set to “REV” for system transient block and unequal pole external fault
clearing.
b) The minimum setting of FDGT should be 3 cycles unless for some special application.
c) Refer to section 3.4.7 for the setting of CIF if two REL300 relays control a single breaker and share a
common 52b output.
2. LOAD LOSS TRIP (LLT)
For a system if its maximum tapped load may exceed minimum through-load in the protected line, the set-
ting of LLT should be set to “NO”. Refer to section 3.4.9 for the detailed information.
3. PHASE ROTATION
Check JMP-3 on the Microprocessor module. Position JMP-3 is used for ACB rotation if a jumper is placed.
Normally JMP-3 should be out for a system with phase rotation ABC.
4. PANG, GANG and ZR SETTINGS
The settings of PANG and GANG have been expanded from 40-90 to 0-90 degrees and the ZR setting has
been changed from 0.1-7.0 to 0.1-10.0 for underground cable application. The setting rule of PANG, GANG
and ZR must be followed: if the setting difference of PANG and GANG is greater than 50 degrees OR the
ZR setting is greater than 7.0, the operating range of the maximum fault current should be limited to 200
amperes; otherwise, the microcontroller may give an un-predicted result.
NOTE: CONVERSION FROM REL300 FIRMWARE VERSION V2.70 to V2.71 CAN BE
ACCOMPLISHED AS FOLLOWS:
1. Standardprecautionsofstaticvoltagedischargesshouldbeobservedsuchasusingagroundedwriststrap
when handling Integrated Circuits.
2. Remove chips U103, U104, and U202 from the Microprocessor module.
3. Replace chips U103 (G19) and U104 (G20) and U202 into the sockets.
4. Check Jumper #3 on Microprocessor module for rotation ABC or ACB system which is shown on the Me-
tering mode. Normally, JMP3 should be “OUT” for ABC system. Spare jumpers should be placed on loca-
tions JMP10, 11 or 12. Remove any spare jumper (JMP10, 11 or 12) and replace it to JMP3 position for
ACB system.
5. Check Jumper #2 on Microprocessor module. Position 2-3 is used for single-pole trip logic only and posi-
tion 1-2 is used for three-pole trip or programmable output contact logic.
6. Reprogram REL300 password through INCOM®remote communication.
7. It is recommended to verify the relay’s operation per Section 2 of Appendix H (Acceptance/Maintenance
Tests).
