Line PT:The Line PT is located on line side of the Feeder.
This will have normally has two secondary cores.The core
with accuracy cl.1 is used for metering purpose(ie)
measuring Voltage,watt,var etc. Core with accuracy cl.3P is
used for Porotection like distance scheme relay,
directional O/C,E/F relay. Also metering secodary core is
used synchronising the line with Bus.
Bus PT : The Bus PT functions are same as Line PT. But This
is located on the main Bus and this can be used for all the
circuits being located in the Bus. For cost point of view
it better to have common Bus pt for all the circuits.
