Which
of the following is INCORRECT regarding the classification of substations on
the basis of operating voltage?
High voltage substation
Ultra-low voltage substation
Ultra-high
voltage substation
Extra-high voltage substation
Ultra-low voltage substation
Based
on the operating voltage ultra-lowvoltage sub station is not classified.
Electrical
sub-station classified on the basis of the following components :
1.
Depending on the nature of Duty/ service.
2.
On the basis of control.
3.
On the basis of electrical nature.
4.
On the basis of importance/necessity.
5.
On the basis of mounting and design.
Classification
of sub-stations on the basis of operating voltage.
1.
Low voltage sub-station
2.
High voltage sub-station
3.
Extra high voltage sub-center from 132 kV to 400 kV.
4.
Ultra high voltage sub-station grater than 400 kV.
Hence,
the correct option is (B).
