3 TANSFOMES THE STANDAD TANSFOME FO SINGLE-PHASE UNDEGOUND SYSTEMS IS THE PAD-MOUNTED TYPE WITH AN INTENAL, HIGH VOLTAGE WEAK LINK AND BAYONET FUSE. ALL UNITS HAVE A LOADBEAK ELBOW FO VISIBLE DISCONNECT MEANS ON EACH OF THE TWO HIGH-VOLTAGE CABLES. WHEE TANSFOMES HAVE TWO DISCONNECT BUSHING WELLS AND ONLY ONE CABLE ELBOW IS TO BE CONNECTED, A BUSHING AND DEAD-END ECEPTACLE AE TO BE INSTALLED IN THE UNUSED WELL. UNUSED CABLE ELBOWS AE TO HAVE A PLUG O BUSHING. THE STANDAD SINGLE-PHASE TANSFOME IS MILD STEEL. SPECIAL 4L SEIES STAINLESS STEEL UNITS AE AVAILABLE FO THE DEFINED COASTAL AEAS. THE STANDAD TANSFOME FO THEE-PHASE UNDEGOUND WYE-SECONDAY SYSTEMS IS THE PAD-MOUNTED TYPE WITH AN INTENAL, HIGH VOLTAGE WEAK LINK AND BAYONET FUSE. ON ADIAL FEED SYSTEMS, POTECTION MUST BE POVIDED BY FUSES ON THE DIP POLE SIZED ACCODING TO FUSING TABLES. TANSFOME PADS TANSFOME PADS AND ALL ASSOCIATED PEPAATIONS FO A TANSFOME SHALL BE CONSTUCTED ACCODING TO SECTION 4. THE EATH SHALL BE LEVEL AND THOOUGHLY TAMPED TO GIVE COMPACTION ESSENTIALLY EQUIVALENT TO UNDISTUBED EATH BEFOE PADS AE INSTALLED. THE PADS MAY BE PECAST O POUED AT SITE. THOSE PADS POUED AT SITE SHALL BE ALLOWED TO SET A MINIMUM OF THEE DAYS BEFOE THE TANSFOME IS PLACED. TANSFOME INSTALLATION AT ALL STAGES OF TANSPOTING AND INSTALLING, CAE SHALL BE TAKEN TO AVOID SCATCHING O DAMAGING THE TANSFOME EXTEIO. DAMAGED AEAS MUST BE TOUCHED-UP WITH PAINT. DO NOT INSTALL TANSFOMES OVE CULVETS, DAIN LINES O DOP INLETS. CAE SHOULD BE TAKEN IN PLACING THE TANSFOME ON THE PAD SO AS TO AVOID DAMAGE TO CABLES AND OTHE EQUIPMENT. THE TANSFOME SHALL BE SECUELY BOLTED TO PAD USING THE BOLTS CAST INTO THE PAD O OTHE APPOVED FASTENES. LIFTING BOLTS ON EACH SIDE OF A SINGLE-PHASE TANSFOME SHOULD BE EMOVED AFTE THE TANSFOME IS INSTALLED. THESE MAY BE KEPT FO FUTUE USE. THE CONTACT SUFACE BETWEEN THE TANSFOME AND PAD SHALL BE TAMPE-POOF. ANY SPACE BETWEEN THE BOTTOM OF TANSFOME CABLE COMPATMENT AND PAD SHALL BE FILLED WITH GOUT ON THE INSIDE OF THE TEMINAL COMPATMENT. NO DIT SHALL BE IN CONTACT WITH THE TANSFOME.

4 IDENTIFICATION POCEDUES ONE OF THE MAJO DIFFEENCES BETWEEN OVEHEAD AND UNDEGOUND DISTIBUTION IS THAT THE SOUCE OF FEED FO THE VAIOUS CABLES AND APPAATUS CANNOT BE VISIBLY TACED IN THE UNDEGOUND SYSTEM. A COMPLETE IDENTIFICATION METHOD MUST BE USED FO UNDEGOUND POJECTS. IT MUST BE SIMPLE, PEMANENT, AND EASILY IDENTIFIABLE IN ODE TO KNOW THE SOUCE, DIECTION OF FEED, AND TEMINATION POINT OF THE CONDUCTOS. ALL TEMINAL POLES, PADS, TANSFOMES, PEDESTALS, PIMAY PHASES, AND ANY OTHE APPAATUS SHALL BE NUMBEED O LETTEED ON LAYOUT MAPS ON THE SYSTEM BY ENGINEEING BEFOE CONSTUCTION IS STATED. DUING CONSTUCTION, ALL CABLE ENDS MUST BE TAGGED BEFOE TENCHES AE BACKFILLED. IF TEMPOAY TAGS AE USED DUING CONSTUCTION, PEMANENT TAGS MUST BE INSTALLED BEFOE THE SYSTEM IS ENEGIZED. THE LETTES X, Y, AND Z AE USED TO IDENTIFY DIFFEENT UNDEGOUND PHASES. THIS IS DONE TO PEVENT CONFUSION IF THE OVEHEAD PHASES A, B, AND C SEVING THE UNDEGOUND AE LATE SWAPPED. POTECTION AND COODINATION LIGHTNING POTECTION SHALL BE POVIDED BY A DIECT-CONNECTED ISE POLE TYPE AESTES INSTALLED ON EACH CABLE AT ALL NEW TEMINAL POLES. IN ADDITION, ON ALL NEW ESIDENTIAL INSTALLATIONS, IF THE TANSFOME AT THE OPENING POINT OF THE UNDEGOUND SYSTEM DOES NOT CONTAIN AN INTENAL AESTE, AN ELBOW AESTE SHALL BE INSTALLED. POTECTION AGAINST FAULT CUENTS SHOULD BE POVIDED BY A SECTIONALIZING FUSE, ON ALL CABLE TEMINAL POLES AS SPECIFIED BY THE ENGINEE. CAE SHOULD BE TAKEN TO ENSUE THAT THE POTECTIVE DEVICE ON THE TEMINAL POLE POPELY COODINATES WITH THAT IN THE LAGEST TANSFOME IN THE LOOP, AS WELL AS THE NEXT OVEHEAD POTECTIVE DEVICE TOWAD THE SUBSTATION. GOUNDING DIVEN GOUND ODS SHALL BE POVIDED AT EACH CABLE TEMINAL POLE AND AT EACH TANSFOME. GOUND LEADS FOM THE DIVEN GOUNDS SHALL BE SOLIDLY CONNECTED TO THE PIMAY NEUTAL, THE SECONDAY NEUTAL, AND TO THE GOUNDING CONNECTION OF ALL EQUIPMENT. EPLACEMENT POLICY DISTIBUTION TANSFOMES AE PIMAY COST COMPONENTS IN POVIDING CUSTOME SEVICE. THE ESTIMATED SEVICE LIFE FO TANSFOMES IS YEAS. TANSFOMES SHOULD NOT BE EPLACED UNLESS ABSOLUTELY NECESSAY. DO NOT EPLACE A TANSFOME UNLESS: PHYSICAL DAMAGE OCCUS THAT CANNOT BE FIELD EPAIED SUCH AS BOKEN BUSHINGS, USTING, LEAKING OIL, LOCKING POBLEMS, DAMAGED DOOS, ETC. BEFOE EPLACING THEE-PHASE PAD-MOUNTED TANSFOMES, CHECK WITH TANSFOME EPAI SHOP TO SEE IF UNIT CAN BE EPAIED IN FIELD. THE CONDITION OF THE TANSFOME IS AN IMMEDIATE SAFETY HAZAD. THE TANSFOME IS OVELOADED. THE TANSFOME IS UNDELOADED AND CAN BE ECONOMICALLY DOWNSIZED. THE TANSFOME IS AN OBSOLETE SINGLE-PHASE LIVE FONT PAD-MOUNTED AND THE UNDEGOUND CABLE IS ALSO BEING EPLACED. THE TANSFOME IS KNOWN TO HAVE A PCB CONCENTATION OF 5 PPM O MOE. TANSFOMES SHOULD NOT BE EPLACED WHEN DOING UNDEGOUND PIMAY CABLE EPLACEMENT UNLESS THEY AE LIVE FONT SINGLE-PHASE UNITS. ALSO, TANSFOMES SHOULD NOT BE EPLACED WHEN THE PIMAY NON-LOADBEAK ELBOWS AE BEING EPLACED WITH LOADBEAK ELBOWS. THE BUSHING INSETS SHOULD BE EPLACED ATHE THAN THE ENTIE TANSFOME. EINSTALLATION POLICY ONLY NON-PCB TANSFOMES (LESS THAN 5 PPM) AS SHOWN BY BLUE DOT, BLUE NON-PCB LABEL, O NAMEPLATE SHOULD BE INSTALLED. ANY TANSFOME OF UNKNOWN PCB CONTENT THAT HAS BEEN EMOVED FOM SEVICE SHOULD HAVE A "PCB ATICLE STOAGE FO EUSE" LABEL PLACED ON IT ( CN 9667) AND SENT TO THE GANE TANSFOME SHOP. THE LABEL MUST BE PLACED ON THE TANSFOME AS SOON AS IT AIVES AT THE L&S YAD. NON-PCB TANSFOMES IN OPEABLE CONDITION SHOULD BE ESTOCKED AND E-USED. DO NOT SEND OPEABLE TANSFOMES TO THE TANSFOME SHOP UNLESS THEY NEED EPAI, PAINTING, TESTING, O HAVE A KNOWN O ASSUMED PCB CONTENT OF 5 PPM O MOE. A PAD-MOUNTED TANSFOME OF UNKNOWN PCB CONTENT MAY NOT BE TANSFEED IN THE FIELD. 6// SIMMONS GUINN ELKINS UNDEGOUND DISTIBUTION SPECIFICATIONS 7.-

16 POGESS ENEGY STANDAD POCEDUES BULLETIN IDLE TANSFOMES DEFINITION: AN IDLE TANSFOME IS A TANSFOME THAT IS INSTALLED ON THE DISTIBUTION SYSTEM BUT IS SEVING NO USEFUL PUPOSE. THEE IS NO CUSTOME BEING SEVED, NO LIGHTS, NO TAFFIC SIGNALS. THEE IS ALSO NO EASONABLE POTENTIAL FO SEVING A CUSTOME IN THE FUTUE. A TANSFOME INSTALLED IN A NEW UNDEGOUND DEVELOPMENT THAT IS SEVING NO CUSTOMES BUT WILL IN THE FUTUE IS NOT CONSIDEED IDLE BECAUSE IT WILL BE SEVING CUSTOMES IN THE NEA FUTUE. EXAMPLES AE AS FOLLOWS:. A TANSFOME THAT WAS USED FO TEMPOAY CONSTUCTION SEVICE IS IDLE AFTE THE CONSTUCTION IS COMPLETED AND THE TANSFOME IS NO LONGE NEEDED FO CONSTUCTION SEVICE.. A TANSFOME THAT SEVED A ESIDENTIAL CUSTOME IS IDLE IF THE HOME IS NO LONGE OCCUPIED AND THEE IS NO POSPECT OF SEVING A CUSTOME AT THE SAME LOCATION.. A TANSFOME BANK THAT SEVED A COMMECIAL/INDUSTIAL CUSTOME IS IDLE IF THE CUSTOME IS NO LONGE IN BUSINESS AND THE TANSFOME BANK IS NOT NEEDED FO A POTENTIAL NEW CUSTOME AT THE SAME LOCATION. ISSUES WITH IDLE TANSFOMES: THEE AE SEVEAL EASONS WHY IDLE TANSFOMES SHOULD BE EMOVED FOM THE SYSTEM. ONE THAT IS LEFT ENEGIZED EXPEIENCES "NO-LOAD" COE LOSSES EVEN WHEN IDLE. THESE AE ANNUAL LOSSES. A 5 KVA TANSFOME IS ESTIMATED TO HAVE $5 OF ANNUAL COE LOSSES. A 67 KVA TANSFOME IS ESTIMATED TO HAVE $ OF ANNUAL COE LOSSES. A TANSFOME THAT IS IDLE IS A POTENTIAL FO VANDALISM, ESULTING IN AN ENVIONMENTAL ISSUE, AN OIL SPILL. THEE HAVE BEEN A NUMBE OF SPILLS DUE TO VANDALISM OF IDLE TANSFOMES AND SOME OF THESE EQUIED SIGNIFICANT COSTS FO CLEANUP. A TANSFOME THAT IS IDLE IS A POTENTIAL HAZAD FO CIMINALS WHO WOULD ATTEMPT TO VANDALIZE THE UNITS TO STEAL COPPE. THEY WILL TAKE EXTAODINAY ISKS WITH NO EGAD FO THEI OWN SAFETY O POPETY OF OTHES. TANSFOME COSTS HAVE INCEASED SUBSTANTIALLY SINCE 4 DUE TO THE ISING COSTS OF AW MATEIALS: COPPE, COE STEEL, MINEAL OIL. COSTS WILL INCEASE AGAIN SIGNIFICANTLY IN JANUAY, AS NEW DEPATMENT OF ENEGY (DOE) EFFICIENCY EQUIEMENTS AE IMPLEMENTED. IT IS A SIGNIFICANT FINANCIAL BENEFIT TO THE COMPANY TO EMOVE AND E-USE IDLE TANSFOMES VESUS BUYING NEW ONES AT SIGNIFICANTLY HIGHE PICES. ONES THAT HAVE BEEN EMOVED AND E-USED DO NOT HAVE TO MEET THE MOE STINGENT EFFICIENCY EQUIEMENTS OF DOE. POCEDUE: ANY TANSFOME THAT IS IDLE BUT LEFT ON THE POLE SHALL BE DE-ENEGIZED TO SAVE ANNUAL COE LOSSES. TANSFOMES WITH NO CUTOUTS (CSP) SHALL HAVE THE HOT LINE CLAMP EMOVED FOM THE PIMAY AND GOUNDED TO THE SYSTEM NEUTAL. TANSFOMES WITH CUTOUTS MAY BE DE-ENEGIZED BY OPENING THE CUTOUT AND EMOVING THE CUTOUT BAEL. WHEN A TANSFOME HAS BEEN DE-ENEGIZED, ASSET ENGINEEING SHALL BE NOTIFIED. ASSET ENGINEEING WILL EVALUATE AND DETEMINE IF THE TANSFOME SHOULD BE EMOVED AND IF SO, PEPAE A WOK ODE TO EMOVE. ASSOCIATED EQUIPMENT (CUTOUTS, AESTES, SEVICE CONDUCTOS, ETC.) SHOULD BE EMOVED AT THE SAME TIME THE TANSFOME IS EMOVED. FO TANSFOME BANKS SEVING COMMECIAL O INDUSTIAL CUSTOMES, CONTACT WITH ACCOUNT MANAGES WILL BE EQUIED TO DETEMINE IF THEE IS POTENTIAL FO FUTUE CUSTOMES OCCUPYING A VACANT FACILITY. TANSFOMES THAT HAVE BEEN EMOVED SHALL BE PLACED IN STOCK AT THE LOCAL STOEOOM, IF THE TANSFOME IS IN GOOD CONDITION AND IS NON-PCB. IF NOT IN GOOD CONDITION, O THE PCB CONTENT IS UNKNOWN, THE TANSFOME SHALL BE ETUNED TO THE GANE TANSFOME SHOP WHEE IT WILL BE EVALUATED, EPAIED, EPAINTED AND ETUNED TO STOCK, IF POSSIBLE. 6// SIMMONS GUINN ELKINS IDLE TANSFOMES 7.-
