A further update on this site.
We did discover high third-order harmonics coming from the utility by using a power quality meter. In turning over this design to a power quality expert, they came back and pointed out that our wye-wye system needed neutrals to be code compliant. I have been...
1. All generators are two-thirds pitch.
2. All generators synchronize across the low voltage circuit breakers. They then ramp up to load. Right now we are only running one generator at a time for peak shaving.
3. All generators synchronized at the time of commissioning. Both 52-G2 and 52-G3 can...
Greetings,
I have a system where we are burning the neutral to ground bonds on two 480V Y / 277 with a two-thirds pitch natural 1400kW gas generator alternator. (I have attached a single line and a screenshot of the transformer data.) Each generator has a step-up transformer that is...
