Answer / rsbangra

as per question bus coupler is couple two bus systems .
as otherways if two sourse of supply at same voltage same
frequency and and same phase sequence we can couple in
running and off condition of one source.
advantage
we can parralle two lines by bus coupler
we shift load one bus to other bus.
we can charge both bus by one sourse in case of one sourse
failure.

Answer / aamirali

Bus Coupler is used to connect the two or more incoming and outgoing buses (Same voltage & frequency)and under the abnormal conditions we can shift the load on an other bus, without any interruption this is big advantage .
Types of Buses:
1. Fixed v & angle, vary P & Q
2. Fixed P & Q, vary V & Angle
3. Fixed P & v, vary Q & Angle
