Why Is Isolated Neutral Preferred In Some Turbines/Generators?
Dear engineers,
I need your help in analyzing this query:
Our plant consists of 11x 635 KW, 415V Waukesha gensets, 2 x 3.5MW,11KV wartsila gensets, 11 KV main bus for synchronization & 10 MW,11KV, 50 Hz gas turbine. The neutral of gas turbine is earthed against the manufacturers recommendations.
Now, a 2.7MV, 11KV, 50 Hz steam Turbine is being added to the system whose neutral is recommended to be earthed. but before taking this action the Neutral of existing Gas Turbine is to be un-earthed.
I am not asking from manufacturer's point of view but I am simply asking from synchronization point of view. Any questions will be welcomed!
THANKING IN ADVANCE 😀
