I work in a 210MW thermal Power plant. Here, the Generator is grounded through 50KVA, 15.75KV/240-120V NGT. The stator E/F relay used for 95% to 100% of the stator windings protection has got "Broken Delta arrangement". My question is, how does it differ from "Open Delta configuration"? What are the benefits of using Broken Delta? Please send me more details about this. I'm new to this concept. If possible tell me more details about Broken Delta & Stator E/F detection.
