Nothing harm in placing the breaker beffore 1km distance,
but the system will suffer with the following disadvantages.
1) One KM long cable protection has to be taken care which
will cost heavily.
2) local supply providing authorities may object, since
this kind of arrangement is not allowed as per ie rules.
3)Running the pilot wires for the protection signal
sampling and the control wiring of the breaker will become
a tedious job.
4)Proper and cautious co-ordination is required in the
operation and maintenance point of view before every
operation.
