Hello friends, Can anyone explain the concept of zones in
Bus bar protection and how can we differentiate the main
zone and check zone in Bus bar protection
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.
