                 I.   IN-HOUSE DEVELOPED AUXILIARY CONVERTER (GTO) TESTING
                      ARRANGEMENT:

           Traditionally Electronic Cards and Modules of GTO Auxiliary converters were
           being  off-load  tested  on  shop  floor.    On-load  testing  was  done  only  after
           installing in the locomotive. This resulted in additional time and also affected
           the quality of testing. To overcome the above, a new testing arrangement
           has  been  made  available  at  the  shop  floor  to  check  the  functioning  of

           complete  Auxiliary  Converter  with  prescribed  load.    This  testing  panel
           comprises  of  an  Electro  Magnetic  Device  make  Single  Phase  180  KVA
           transformer having voltage rating of 415V AC with variable output voltage
           range up to 1200V AC equipped with safety feature of over current tripping.
           Voltages  and  frequencies  are  measured  at  required  points  and  the
           complete functionality of Auxiliary Converter is ensured in the lab itself. This
           arrangement  has  enabled  shed  to  carry  out  complete  repair  of  GG/WRE
