synchronization: 2 questions
(OP)
1-Is it OK?
- bus running refers to system bus
- bus incoming refers to generator bus
2- phase-to-phase voltage synchronization is best than
phase-to-neutral voltage synchronization ?
- bus running refers to system bus
- bus incoming refers to generator bus
2- phase-to-phase voltage synchronization is best than
phase-to-neutral voltage synchronization ?






RE: synchronization: 2 questions
2. I prefer Phase-Phase voltages with both running and incoming voltages derived from voltage trsnformers with grounded secondary circuits to prevent floating voltages. Line-neutral also works.
It is best to monitor the voltages to the synchronizer or synch scope with either voltmeters or a synch check relay with uner/over voltage elements to detect fuse or VT failure that may give false synch voltages.
