FIELD OF THE INVENTION 
       [0001]    This invention relates to the field of repair or re-conductoring of energized conductors and to the use and re-use of temporary conductors in the manner of a tool which is used over and over again as work progresses from section to section along energized power lines. 
       SUMMARY OF THE INVENTION 
       [0002]    A method of using a piece of conductor as a tool, wherein the method is for use in live re-conductoring of energized phases, at a voltage potential, strung, in at least a first section, between at least first and second supports, and also in a contiguous second section, contiguous to the first section, between the second and a third support,
       wherein in both the first and second sections of the energized phases or conductors are contiguous between the first and second sections,   and wherein the energized phases or conductors comprise a spaced apart energized array of energized conductors, which may be substantially parallel, and which may be vertically or horizontally aligned vertically spaced apart energized array of energized conductors, wherein the energized conductors comprise separate phases,   the method comprising in the first section:
           a) providing a re-usable set of temporary conductors,   b) stringing the temporary conductors in a substantially aligned, spaced apart temporary array alongside, and spaced apart from, the energized array so that each energized conductor of the energized array has a corresponding temporary conductor of the temporary array alongside it,   c) commencing with a first energized conductor of the energized array, energizing so as to bring a corresponding first temporary conductor of the temporary array to the voltage potential of the first energized conductor, paralleling the first temporary conductor with the first energized conductor, and then de-energizing the first conductor,   d) maintaining, for example, repairing or re-conductoring, the de-energized first conductor or delaying the maintenance,   e) repeating in sequence steps (a) through (d) for each subsequent energized conductor in the energized array and corresponding temporary conductor in the temporary array,   f) for those energized conductors not maintained in step (d), then maintaining those energized conductors, then,   g) re-energizing the conductors and paralleling the energized conductors with the temporary conductors,   h) de-energizing the temporary conductors,   i) removing the temporary conductors for later re-use as a tool in the second section, the method further comprising in the second section:   j) providing the set of temporary conductors,   k) repeating steps (b) through (i), whereby the maintenance on the first and second sections occurs without transposing relative positions of the energized conductors in the energized array, and whereby the temporary conductors are re-usable from section to section.   
               
 
         [0017]    The invention is an apparatus, system and/or method as shown, described or implied herein.

     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS 
       [0198]    With reference to  FIG. 1 , what is seen is the layout of support towers, and of the conductors supported by the towers, as seen from above, that is, in plan view.  FIG. 1A  is a side elevation view along line  1 A- 1 A in  FIG. 1 .  FIG. 1B  is a side elevation view along line  1 B- 1 B in  FIG. 1 . A compass orientation is provided in each view for ease of reference between the various labelled phases. The orientation of the compass is by way of example only. 
         [0199]    Thus, as seen in the diagrammatic overview  10 , which is intended to be representative and not limiting, each of support towers  12   d,    12   e,    12   f,  and  12   g  support, on either side of each tower, electrical conductors comprised of three phases; namely, top phase  14   a,  center phase  14   b,  and bottom phase  14   c.  In the illustrated example the main line being reconductored is 345 Kilovolts (KV) and the circuit on the right is 138 KV as indicated by shorter insulators, the 138 KV line phases are identified using reference numbers  15   a,    15   b  and  15   c.  Poles are identified as  17   a,    17   b  and  17   c  and are only labelled in  FIG. 1 . This embodiment is not intended to be limiting as other high voltage loads may also be carried. In the lower portion of  FIG. 1 , because phases of  14   a - 14   c  are stacked vertically one above the other as seen in  FIG. 1B , only top phase  14   a  can be seen. In the upper portion of  FIG. 1A , that is in the upper portion of  FIG. 1  relative to structure  16 , each of the phases diverges in plan view from one another so as to convert from a vertical spaced apart array of phases to a horizontally spaced apart horizontal array of phases  14   a - 14   c  carried by vertical supports  16   a - 16   c  respectively. The horizontal array of phases  14   a - 14   c  is then carried on support structure  18 . 
         [0200]    As carried by support structure  18 , top phase  14   a  is renumbered as horizontal phase  14   a ′. Likewise, center phase  14   b  is relabeled as horizontal phase  14   b ′ and bottom phase  14   c  is relabeled horizontal phase  14   c′.    
         [0201]    The energized re-conductoring method according to one aspect of the present invention is exemplified by the illustrated operations carried out on the layout of  FIG. 1  as shown in the balance of the  FIGS. 2-42 , as those operations are described below. One skilled in the art would know that such operations in a live re-conductoring exercise are highly dangerous and that safety precautions must be followed, so as to avoid hazards such as for example, those discussed in U.S. Pat. No. 7,535,132 entitled Live Conductor Stringing and Splicing Method and Apparatus. 
         [0202]    Commencing in  FIG. 2B , ovals and circles  20 , have been added to highlight in at least one view where changes have been made which affect the representation in the previous view and thus allow for rapid detection by the reader of the changes made by the various steps in the method described herein. 
         [0203]    Thus as seen in  FIG. 2B , the highlight oval  20  is shown around the north arms of tower  12   d  to indicate that changes are made from the representation of tower  12   d  in  FIG. 1B . Thus highlight oval  20  in  FIG. 2B  indicates that a re-usable temporary line comprising temporary phases  22   a,    22   b,  and  22   c  for the temporary top, center and bottom phases respectively have been strung under the corresponding top, center and bottom arms  24   a,    24   b,  and  24   c  respectively of tower  12   d.  The temporary line extends from tower  12   g  via towers  12   f,    12   e  and  12   d  to temporary vertical dead-end  26 , better seen in  FIG. 2A . Temporary phases  22   a,    22   b  and  22   c  are maintained in a vertically spaced apart array from tower  12   g  to temporary vertical dead-end  26 . 
         [0204]    As seen in  FIGS. 3 and 3A , a jumper  28   a  is installed between the top of the pole of vertical support  16   a , that is, the East phase pole top, to the top temporary phase  22   a.  Jumper  28   a  is mounted between corresponding insulators or polymers  29   a  at the opposite ends of jumper  28   a.    
         [0205]    As seen in  FIGS. 4 and 4A , a jumper  30   a  installed between the horizontal phase  14   a,  that is, the East phase, and the temporary jumper  28   a  thereby energizing temporary jumper  28   a.    
         [0206]    As seen in  FIGS. 5 and 5A , a temporary jumper  32   b  is installed from the top of the pole of vertical support  16   b,  that is, from the center phase pole top, to the temporary center phase  22   b.  A pair of insulators or polymers  33   b  is mounted at opposite ends of temporary jumper  32   b,  between temporary jumper  32   b  and the top of vertical support  16   b  and center temporary phase  22   b.    
         [0207]    As seen in  FIGS. 6 and 6A , a jumper  34   b  is installed from the horizontal center phase  14   b  to temporary jumper  32   b  thereby energizing temporary jumper  32   b.    
         [0208]    As seen in  FIGS. 7, 7C and 43 , polymer posts  39   a,    39   a  are installed on the legs of tower  12   d  on each side and positioned above the bushings  38 ,  38  of the first temporary circuit breaker  36 . A transfer bus  40  is run down each side of tower  12   d  between polymer posts  39   a,    39   a  and the bushings  38 ,  38  of the first temporary circuit breaker  36 . 
         [0209]    As seen in  FIGS. 8 and 8C , a jumper  42   a  is installed from the top phase  14   a  to the adjacent transfer bus  40 . With the first temporary circuit breaker  36  verified to be in its open condition, a second jumper  42   a  is installed from the top temporary phase  22   a  to the other side of transfer bus  40 , that is the side of transfer bus  40  adjacent top temporary phase  22   a.  This energizes one side of the first temporary circuit breaker  36 . 
         [0210]    As seen in  FIGS. 9 and 9B , similar to the installation of the first temporary circuit breaker  36  and transfer bus  40  on tower  12   d,  discussed above in relation to  FIG. 7 , a further second temporary circuit breaker  44  and corresponding transfer bus  46  is set up adjacent to tower  12   f.  Transfer bus  46  is installed between the bushings  48 ,  48  on the second temporary circuit breaker  44  and polymer posts  49   a,    49   a  on the legs of tower  12   f,  is set up adjacent to tower  12   f.    
         [0211]    As seen in  FIGS. 10 and 10B , again with the second temporary circuit breaker  44  confirmed open, jumpers  50   a  are installed from top phase  14   a  and transfer bus  46 , and between transfer bus  46  and top temporary phase  22   a  respectively. This energizes one side of the second temporary circuit breaker  44 . 
         [0212]    As seen in  FIG. 11 , a temporary jumper  52   a  is installed on adjacent tower  12   g,  from the top temporary phase  22   a  to a suspension insulator  54   a  on the end of the corresponding arm of tower  12   g,  so as to leave an extra length  53   a  of jumper  52   a  coiled for use later as described below. 
         [0213]    As seen in  FIGS. 12 and 12C , first temporary circuit breaker  36  on tower  12   d  is closed thereby energizing the top temporary phase  22   a  via bus  40  and jumpers  42   a  between vertical support  16   a  and tower  12   g  at the potential of top phase  14   a ′, that is, the East phase potential. 
         [0214]    As seen in  FIGS. 13 and 13B , the second temporary circuit breaker  44  is then closed thereby paralleling the top temporary phase of  22   a  between tower  12   g  and temporary vertical dead-end  26  and top phase  14   a,  that is, the East phase  14   a′.    
         [0215]    As seen in  FIGS. 14 and 14A , a jumper  56   a  is next installed across insulator  29   a  on temporary jumper  28   a  to thereby parallel the top phase  14   a  (East phase  14   a′ ) and top temporary phase  22   a  around vertical support  16   a.    
         [0216]    As seen in  FIGS. 15 and 15A , the parallel around vertical support  16   a  is broken by the removal of permanent jumper  58   a,  seen for example installed in  FIG. 14  and  FIG. 14A , from between East phase  14   a ′ and top phase  14   a.    
         [0217]    As seen in  FIG. 16 , temporary jumper  52   a,  which was installed in the step illustrated in  FIG. 11 , is extended so that the extra length  53   a  of jumper  52   a  is extended to the section of top phase  14   a  heading east from tower  12   g.  This completes a paralleling of top phase  14   a  around the dead-end at tower  12   g.    
         [0218]    As seen in  FIGS. 17 and 17A , the permanent jumper  60   a  as seen for example in  FIG. 16 , is removed from between the sections of top phase  14   a  which are oriented substantially North and East on either side of tower  12   g  thereby breaking the parallel around the dead-end at tower  60   a.    
         [0219]    As seen in  FIGS. 18 and 18B , the second temporary breaker  44  is then opened so as to break parallel of top phase  14   a  and temporary phase  22   a,  between tower  12   g  and vertical support  16   a.    
         [0220]    As seen  FIGS. 19 and 19B , the first temporary breaker  36  is next opened thereby de-energizing top phase  14   a  between tower  12   g  and vertical support  16   a.    
         [0221]    As seen in  FIGS. 20, 20B and 20C , the temporary jumpers  50   a,    42   a  are removed from their corresponding transfer buses  46  and  40  respectively, thereby respectively de-energizing and clearing temporary circuit breakers  44  and  36 . 
         [0222]    Top phase  14   a  may now be worked on or replaced as its energized load has been transferred to, so as to be carried by, top temporary phase  22   a  between tower  12   g  and vertical support  16   a,  or the work or replacement may be delayed until one or more of the other energized phases have been de-energized and the work then done on all of the de-energized phases. 
         [0223]    The steps in the de-energizing of the center and bottom phases,  14   b  and  14   c  respectively, and the transferring of the load to the corresponding re-usable temporary conductor phases, is set out in  FIGS. 21 through 42 . The steps in relation to the center energized phases are set-out in  FIGS. 21-31 . The steps in relation to the bottom energized phase are set out in  FIGS. 32-42 . In the lower portion of  FIGS. 21-31 , because the phases  14   a  through  14   c  are stacked vertically one above the other (as seen in  FIG. 1B ), only the center phase  14   b  is shown, as it is the center phase  14   b  that is being worked upon. 
         [0224]    Similarly, in the lower portion of  FIGS. 32-42 , because the phases  14   a  through  14   c  are stacked vertically one above the other (as seen in  FIG. 1B ), only bottom phase  14   c  is shown. Similarly, as seen for example in  FIG. 2A , because the temporary phases  22   a,    22   b  and  22   c  are stacked vertically one above the other, only the center temporary phase  22   b  is shown in  FIGS. 21-31  (see  FIG. 21 ); and only the bottom temporary phase  22   c  is shown in  FIGS. 32-42  (see  FIG. 32 ). 
         [0225]    It will be understood that, although not shown in the Figures, the de-energized phases  14   a,    14   b,    14   c  may be repaired or replaced, following which the process set out above for each phase is reversed so as to re-transfer the load back from the temporary phases to the now-repaired/replaced phases. Once the temporary phases are de-energized they are removed for re-use in the next section of energized line needing repair or replacement. 
         [0226]    An example is provided of a procedure using a temporary conductor as a removable tool in the repair or re-conductoring (collectively referred to as “re-conductoring”) of three phases in a horizontal configuration. Thus as seen by way of example in  FIG. 44A , a typical H-frame structure having vertical pole  102  and cross-arm  101 , is illustrated. Post suspensions  112  are suspended from cross-arm  101  so as to support conductors  114   a,    114   b  and  114   c.  Conductors  114   a,    114   b  and  114   c  typically carry A phase, B phase and C phase loads respectively. 
         [0227]    As seen in  FIG. 44B , in the example illustrated, a temporary insulator  120  is mounted to the vertical pole  102  closest to conductor  114   a;  that is, the conductor carrying the A phase at the outset of the re-conductoring procedure. As would be known to a person skilled in the art, the arrangement and position of temporary post insulator  120  is merely one example of how the temporary conductor  122 , seen in  FIG. 45 , may be suspended on or from H-frame structure  100 . A further example is provided in  FIG. 57  where temporary insulators  124  are suspended in a “V” arrangement on structure  100  so as to thereby support temporary conductor  122  therebetween. 
         [0228]    Thus, with temporary post insulator  120  mounted to vertical pole  102 , as seen in  FIG. 45 , temporary conductor  122 , which initially is not energized and thus labelled as the “D” phase, is mounted to, so as to be suspended from, the free or distal end of temporary post insulator  120 . In the re-conductoring procedure which follows for the horizontal configuration of conductors seen commencing in  FIG. 44A , the labels “A phase”, “B phase”, “C phase”, and “D phase”, refer, respectively, to an A phase load carried in the corresponding conductor, a B phase load carried in the corresponding conductor, a C phase load carried in the corresponding conductor and a de-energized conductor (the D phase). 
         [0229]    As seen in  FIG. 46 , the A phase load in conductor  114   a  is transferred to temporary conductor  122  as indicated by arrow AA, resulting in temporary conductor  122  carrying the A phase load and conductor  114   a  becoming the D phase upon it be de-energized. That is, the A phase load is transferred to what was the D phase conductor  122  in  FIG. 45 , and the conductor  114   a  which was the A phase in  FIG. 45  is de-energized to become the new D phase. 
         [0230]    As seen in  FIG. 47  once the A phase load has been transferred to temporary conductor  122 , conductor  114   a  may be re-conductored. 
         [0231]    As seen in  FIG. 48  the next step in this embodiment of the procedure is to transfer the B phase load, as indicated by arrow BB, from conductor  114   b  to D phase conductor  114   a  and de-energize conductor  114   b.  Thus the B phase is now carried in conductor  114   a  and, with conductor  114   b  de-energized, conductor  114   b  may be re-conductored as it is now the de-energized D phase as seen in  FIG. 49 . 
         [0232]    As seen in  FIG. 50 , the next step in this embodiment of the procedure is to transfer the C phase load, as indicated by arrow CC, from conductor  114   c  to the now re-conductored conductor  114   b  and to de-energize conductor  114   c.  Thus the C phase load is now carried by conductor  114   b,  and conductor  114   c  becomes the de-energized D phase. With conductor  114   c  now the de-energized D phase as seen in  FIG. 51 , conductor  114   c  may be re-conductored. 
         [0233]    With conductors  114   a,    114   b  and  114   c  now re-conductored, the process is reversed so that, as seen in  FIG. 52 , the C phase load is transferred back to conductor  114   c  as indicated by arrow CC′, and conductor  114   b  de-energized. Thus the C phase load is returned to conductor  114   c,  and  114   b  becomes the de-energized D phase. 
         [0234]    As seen in  FIG. 53 , in the next step of the process, the B phase load is transferred back from conductor  114   a  to conductor  114   b,  and conductor  114   a  is de-energized as indicated by arrow BB&#39;. Thus conductor  114   b  is returned to the B phase and conductor  114   a  becomes the D phase. 
         [0235]    As seen in  FIG. 54 , in the next step of the process, the A phase load is returned from temporary conductor  122  to conductor  114   a,  as indicated by arrow AA′. Thus conductor  114   a  again becomes the A phase and temporary conductor  122  is returned to the D phase. 
         [0236]    As indicated in  FIG. 55 , temporary conductor  122 , that is, the D phase in  FIG. 54 , is now removed so that it may be reused and installed on for example a next section of conductors  114   a,    114   b  and  114   c  to be re-conductored. In  FIG. 56  the temporary post insulator  120  has been removed thereby returning H-frame structure  100  to its original condition.
