A TRANSFORMER VAULT IS AN ENCLOSED COMPARTMENT WITHIN A BUILDING OR BELOW GROUND LEVEL ESPECIALLY DESIGNED FOR THE TYPE TRANSFORMERS SPECIFIED BY THE COMPANY.

A TRANSFORMER ENCLOSURE IS A SPECIAL COMPARTMENT SUITABLE FOR INSTALLING COMPANY'S STANDARDTRANSFORMERS. SUCH ENCLOSURE MAY UTILIZE THE CUSTOMER'S BUILDING WALL(S) AS ONE OR MORE SIDESOF THE ENCLOSURE.

ALL ENCLOSURES MUST HAVE A REMOVABLE COVER APPROVED BY THE ENGINEER EXCEPT THOSE LOCATED INISOLATED OR PROTECTED AREAS WHERE, IN THE WRITTEN OPINION OF THE ENGINEER, THERE IS NO REASONABLY FORESEEABLE DANGER OF ACCESS BY MINORS, WORKMEN AND OTHER MEMBERS OF THE PUBLIC.

ONLY AUTHORIZED COMPANY PERSONNEL SHALL HAVE ACCESS TO TRANSFORMER VAULTS OR ENCLOSURESAND ALL ENTRY DOORS SHALL BE KEPT LOCKED UNLESS ATTENDED.

FERRORESONANCE

FERRORESONANCE IS POSSIBLE WITH UNDERGROUND CABLES AND SINGLE-PHASE SWITCHES FEEDING A DELTAPRIMARY TRANSFORMER BANK OR A FLOATING-WYE TO DELTA TRANSFORMER BANK. THE PREFERRED METHODTO PREVENT THE POSSIBILITY OF FERRORESONANCE IN VAULTS IS TO USE A GANGED SWITCH TO ENERGIZE ORDE-ENERGIZE THE TRANSFORMER BANK. IF THE BANK IS A FLOATING-WYE TO DELTA TRANSFORMER BANK AND ONLY SINGLE-PHASE SWITCHING IS AVAILABLE, FERRORESONANCE CAN BE PREVENTED BY TEMPORARILY

FERRORESONANCE PREVENTION.GROUNDING THE NEUTRAL BEFORE ENERGIZING THE BANK. SEE DWG. 29.03-05 FOR MORE INFORMATION ON

GENERAL

TRANSFORMERS

IT IS THE CUSTOMER'S RESPONSIBILITY TO PROVIDE A TRANSFORMER LOCATION OUTSIDE OF THE BUILDING THAT ALLOWS US TO USE OUR STANDARD MINERAL OIL FILLED TRANSFORMERS AND STANDARD FUSING METHODS. IF THIS IS NOT POSSIBLE, PROGRESS ENERGY WILL INSTALL TRANSFORMERS, SWITCHES ANDFUSES INSIDE A BUILDING IN A CUSTOMER SUPPLIED VAULT THAT IS IN COMPLIANCE WITH NEC ARTICLE 450.THIS ARTICLE STATES THAT UNDER CERTAIN CONDITIONS, MINERAL OIL TRANSFORMERS CAN BE INSTALLEDINSIDE BUILDINGS. HOWEVER, TO AVOID CONFUSION AND TO KEEP PROGRESS ENERGY FROM HAVING TO MONITOR CONTINUED COMPLIANCE WITH THESE CONDITIONS, ALL VAULTS WITHIN A BUILDING WILL BE EQUIPPED WITH TRANSFORMERS USING A LESS FLAMMABLE DIELECTRIC. IN ADDITION THE TRANSFORMER(S) WILL BE FUSED WITH CURRENT LIMITING FUSES. AS MENTIONED IN THE FUSE SECTION ABOVE. THIS CURRENTLIMITING FUSE (CL) REDUCES THE FAULT CURRENT AVAILABLE WITHIN THE TRANSFORMER TANK. THE LESSFLAMMABLE DIELECTRIC, COOPER "FR3", RAISES THE FIRE POINT OF THE TRANSFORMER DIELECTRIC TO ABOVE300° C. THIS COMBINATION GREATLY REDUCES THE CHANCE OF CATASTROPHIC FAILURE DURING A PRIMARY

FAULT IN THE TRANSFORMER.

SPECIAL THREE-PHASE VAULT TRANSFORMERS ARE AVAILABLE. THESE TRANSFORMERS ARE STAINLESS STEEL UNITS AND ARE FILLED WITH LESS-FLAMMABLE FLUID. THEY ARE ALSO FULLY RATED FOR OPERATION IN A 50°C

FOR VAULT TRANSFORMER BANKS CONSISTING OF BANKED SINGLE-PHASE UNITS, STANDARD SINGLE-PHASEDOUBLE BUSHING TRANSFORMERS CAN BE USED PROVIDING THEY ARE MODIFIED. USE A STANDARD STAINLESS STEEL UNIT WHEN AVAILABLE. THESE UNITS SHOULD BE DRAINED AND FLUSHED OF THE EXISTING MINERAL OILAND FILLED WITH A LESS-FLAMMABLE FLUID SUCH AS FR3. ARRANGEMENTS SHOULD BE MADE WITH THETRANSFORMER SHOP TO HAVE THIS DONE. THE TRANSFORMERS SHOULD ALSO BE CONVERTED FROM LIVEBUSHINGS TO BUSHING WELLS IN THE TRANSFORMER SHOP. THE TRANSFORMERS SHOULD BE DERATED FOROPERATION IN THE HIGHER AMBIENT TEMPERATURE CONDITIONS BY 1.5% FOR EACH 1°C ABOVE A 30°C

AMBIENT.

DELTA BANKS SOURCED BY AN UNDERGROUND CIRCUIT SHOULD HAVE A GANGED THREE-PHASE SWITCH TO ENERGIZE ANDDE-ENERGIZE THE BANK. THIS CAN BE DONE BY USING A GANG OPERATED PMH OR VAULT SWITCH. FUSING FOR THE BANK CAN BEON THE DIP POLE OR AT THE TRANSFORMER LOCATION.

FLOATING WYE-DELTA BANKS SOURCED BY AN UNDERGROUND CIRCUIT SHOULD BE ENERGIZED BY A GANG OPERATED SWITCH OR BYTEMPORARILY GROUNDING THE FLOATING NEUTRAL WHILE THE BANK IS ENERGIZED FROM A SINGLE-PHASE SOURCE SUCH AS FUSEDCUTOUTS OR SINGLE-PHASE DISCONNECTS. TEMPORARY GROUNDING SHOULD BE DONE BY BRINGING THE FLOATING NEUTRAL TO THEFRONT OF THE TRANSCLOSURE OR VAULT.

SOME OF THE TERMS USED WITH TRANSFER SCHEMES ARE LISTED BELOW WITH AN EXPLANATION:

TRANSFER TIMER:

AN ADJUSTABLE TIMER, FROM 2-60 SECONDS, THAT ALLOWS THE ENGINEER TO DELAY THE TRANSFER FROMTHE PREFERRED TO THE ALTERNATE SOURCE. THIS CAN BE SET TO COORDINATE WITH ANY OF THE FEEDERBREAKER OR RECLOSER DELAYED OPERATIONS ALLOWING THE TRANSFER TO TAKE PLACE FOLLOWING A QUICKTRIP THAT DID NOT CLEAR THE CIRCUIT OR ALLOWING PREFERRED SOURCE FEEDER BREAKER OR RECLOSER

AUTO-MAN RESTORE SWITCH:

IF SET IN AUTO, THE LOAD WILL BE RETURNED TO THE RE-ENERGIZED PREFERRED SOURCE. IF SET IN MAN, THELOAD WILL REMAIN ON THE ALTERNATE SOURCE EVEN AFTER THE PREFERRED SOURCE IS RE-ENERGIZED. INTHE MAN POSITION, SERVICE PERSONNEL WILL MANUALLY HAVE TO SWITCH BACK TO THE PREFERRED SOURCE.

RESTORE TIMER:

AN ADJUSTABLE TIMER, FROM 5-180 SECONDS, THAT ALLOWS THE ENGINEER TO DELAY THE AUTOMATICTRANSFER BACK TO THE RE-ENERGIZED PREFERRED SOURCE.

NOTE: THE TRANSFER BACK TO THE PREFERRED SOURCE OCCURS ONLY IF THE RESTORE SWITCH IS SET IN THEAUTO POSITION.

CLOSE-OPEN TRANSITION SWITCH:

THIS DETERMINES WHETHER THE PREFERRED AND ALTERNATE SOURCE WILL BE PARALLELED DURING THE AUTORESTORE SEQUENCE. IF SET TO CLOSE, FOLLOWING THE TIMING OUT OF THE RESTORE TIMER, THE PREFERREDSOURCE WILL CLOSE BEFORE THE ALTERNATE SOURCE OPENS. THIS PARALLELS THE TWO SOURCES FOR ONLY6 CYCLES WHICH IN MOST CASES IS NOT LONG ENOUGH TO AFFECT LOAD FLOWS OR ALLOW REGULATORS TOTHE VOLTAGE CHANGES. THIS ALLOWS THE RESTORATION TO THE PREFERRED SOURCE WITHOUT THE CUSTOMER EXPERIENCING WHAT LOOKS LIKE A QUICK TRIP OPERATION. IF SET TO OPEN, FOLLOWING THETIMING OUT OF THE RESTORE TIMER, THE ALTERNATE SOURCE WILL OPEN AND THEN 6 CYCLES LATER, THE PREFERRED SOURCE WILL CLOSE. THE CUSTOMER WILL EXPERIENCE A MOMENTARY DURING THIS OPERATION.

FAULT-BLOCK:

FAULT BLOCK PREVENTS A FAULTED CIRCUIT FROM BEING TRANSFERRED TO THE ALTERNATE SOURCE BYSENSING OVERCURRENTS ON THE LOAD SIDE FAULT DETECTORS. THIS LATCHES THE NORMAL TRANSFERSCHEME OUT AND ONLY ALLOWS THE PREFERRED SOURCE TO OPEN WITHOUT THE ALTERNATE SOURCE CLOSING. THE INDICATOR IN THE CONTROL CABINET WILL BE LIT WHEN SERVICE PERSONNEL ARRIVE AND

BLOWN FUSES ARE REPLACED AND THE FAULT BLOCK BUTTON IS PUSHED, THE SYSTEM WILL AUTOMATICALLYTIME OUT AND RESET TO NORMAL. IF THE FAULT BLOCK LATCHES DUE TO INRUSH CURRENT BUT THERE IS NOLOSS OF VOLTAGE, A TIMER WILL RESET THE FAULT BLOCK AND THE SYSTEM WILL RETURN TO NORMAL WITH NO TRANSFER OCCURRING. WITH FUSES LOCATED ON THE LOAD TAP, FAULTS WILL BE CLEARED BY THE FUSESAND EVEN THOUGH THE FAULT BLOCK DETECTORS WILL LATCH THE FAULT, NO UNDER-VOLTAGE WILL OCCUR AT THE SENSORS AT THE PREFERRED SOURCE ELBOWS AND THE INRUSH RESTRAINT TIMER WILL CANCEL

FOR PAD-MOUNTED TRANSFERS, THERE ARE SEVERAL PACKAGES AVAILABLE THAT (LIKE THE SUBMERSIBLE

DISTRIBUTION STANDARDS FOR ASSISTANCE IN DESIGN AND ORDER INFORMATION.VERSION SHOWN ON DWG. 29.06-03) CAN BE TAILORED FOR SPECIAL APPLICATIONS AS NEEDED. CONTACT

TO LOCKOUT BEFORE TRANSFERRING TO THE ALTERNATE SOURCE.

NOTES:

1. TRANSFORMERS ARE DESIGNED FOR THE ENCLOSED ROOM VAULT ENVIRONMENT. SPECIAL FEATURESINCLUDE 304L STAINLESS STEEL TANK, DELTA-WYE SWITCH, TAP CHANGER, INTERNAL CARTRIDGEEXPULSION FUSE, LOW-FLAMMABLE OIL, JACKING AND ROLLING PROVISIONS AND A TOP OILTHERMOMETER.

2. UNITS ARE RATED 55°C RISE AND DESIGNED FOR OPERATION IN ENCLOSED LOCATIONS AT AMBIENT

TEMPERATURES OF UP TO 50°C.

3. UNITS SHOULD BE INSTALLED WITH AN EXTERNAL FULL-RANGE CURRENT LIMITING FUSE FOR PROTECTION.

4. THE 3000 KVA UNIT (NO LONGER PURCHASED) IS A STANDARD 65°C RISE UNIT RATED FOR 30° AMBIENT.

PER IEEE STD. C57.91, THIS UNIT SHOULD BE DE-RATED 1.5% FOR EACH DEGREE CELCIUS ABOVE 30°C

AMBIENT. IN A 50°C AMBIENT ENVIRONMENT, ITS RATING WOULD BE ONLY 2100 KVA.

5. WHILE SOME SPARES ARE STOCKED IN GARNER, ALL UNITS SHOULD BE CONSIDERED AS SPECIAL-ORDERNON-STOCK.

6. SEE DWG 29.09-03 FOR OUTLINE DRAWING AND DIMENSIONS.
