I am a little bit confuse about the conductor per phase and ECC in mm2 as mentioned in the attached figures.
In the above figure there is a data of a Substation containing Feeder-pillars and the second figure contains the data of Feeder-pillars.
Can any one help me about these two terms.
Why number of conductor per phase in Substation is Two while number of conductor per phase in Feeder-pillar is one.
And what ECC Stands for?
Is it a abbreviation or some kind of unit?
Earth Continuity Conductor ( half the size of the phase cable?). I would say that the feeder pillar is what at lower power we would call a tag block, its got one cable in and two cables out.
