Isolator Interlocking Conditions!?

In case if we have to open/close the isolator of 110 kV Bus Section then what are the Interlocking conditions? Is it necessary that one of the two buses must be isolated and at 0 V before open/close operation.
Please share any link or refer a book where I can find the interlocking conditions for the main substation equipment.
Many thanks.
