can somebody explain control wiring indian / IEC standard ? i am looking forward for the standard which explains different types of ferrules which are used in 132/33/11 KV substations such for cts / pts/ auxilary wiring in control panels.
Some of the pdf circuits are not easy to read,
some have errors, this is mainly due to the importing of schematics
from an older ORCAD
Dos Version. I have corrected some circuits, some are to be checked.
Also some circuits were not corrected after they were drawn by New
Learners, as i wanted them to document what they learnt and familiarize
with computers, Some did a good
job. This section has no electronic parts, so you can figure out the
diagrams.
The Control Panel on the right is a Multi
Zone Temperature Control panel used in Plastic Extrusion Moulding. We
made many of these and it helped us learn cable management techniques.
The panel is a standard way it was built and some of the merits were
the selection of panel components and wiring expertise.
Just like rackmounts hold big instruments or computers, control panels
small or big have to hold DIN Instruments, switches and annunciators to
make it easy for the operator. The maintenance work also is simple from
the backside. It can be kept near the machinery which it controls.
Some Control panels go into Control Rooms at a distance away or at a
greater height from the shop floor. This way they can monitor and give
instructions while managing a larger process like processing of
chemicals and at the same time safeguarding the instrumentation and
computers with controlled
