Hello friends, Can anyone explain the concept of zones in Bus bar protection and how can we differe..

Answer / veldhaya

hi dear,
Zones are classified on the basis of factors like
1.Bus sectionaliser
2.Bus coupler

We can differentiate the Main zone & check zones using
Main zones need to monitor both the Current input & the Isolator input of a particular bay whereas Check zones need to monitor the Current input of a particular bay.
