Audit of
following Work Instructions was done in Shop # 19. Report is as follows:-
Manufacturer
of BA panel ( W 19.005):-
Points noticed:-
- BA panel frames ( Mostly of M/S Modern) were rusted at many
places. This was either due to inferior paint or due to outdoor storage in
CLW
- Busbar to earth clearances of 60 mm as prescribed in para 3.9 of
this WI are to be strictly maintained.
- Para 3.6 of this WI needs modification. QD and Q20 have gone into
CPU nowadays and SHAA has become SHTM.
- Arc chute bolt and nuts material should be same.
- Gas welding quality needs improvement.
- Line contactors of M/S Stesalit
make had spring washers whereas CLW make don’t have spring washers.
This needs to be addressed by design.
