Draw a neat labelled diagram of feeding post and write any four points related to it.
Feeding post: 1) Each feeder has two conductors one insulated for 25 kV (connected to bus-bar) and other for 3 kV (connected to track for return current). 2) Located as near as possible to substation with maximum distance being 2 km. 3) Feeders connected to two sets of bus-bars which are used to maintain supply to OHE in case of failure of one of them or when under maintenance. 4) The 25 kV CB of FP are controlled from RCC of railway. 5) Interlocked double pole isolators provided on both side of CB. 6) The interrupters which are remotely controlled are supposed to operate only under normal current as they are not provided with protection for the same.
