Line PT is connected in the incomer (line) to detect the
voltage of the incomer whereas bus PT is connected in the
bus, 1 before the bus coupler and another after bus
coupler, to detect voltage in the bus.
The main purpose of both of them is to sense the voltage so
that the breaker can get enough information to operate..
