A double-ended switchgear is fed from 2 utility 2000 kVA
transformers during normal operating condition (Utility Mode), with
tiebreaker Normally Open. When Normal power is lost, a 2000 kVA
standby generator G1 feeds the left-side of the switchgear via an
Automatic Transfer Switch (ATS1), and another 2000 kVA generator G2
feeds the right side of the switchgear via ATS2. Tiebreaker between
the right side and the left side of the switchgear is Normally Open
during normal operation.
The following data is given below:
