Electrical Protection for Diesel Generators in Nuclear Power Plants

Summary

> The application of numerical protection relays brought about

considerable benefits in terms of enhanced performance, reliability

and availability of the protection system

> The increase in functionality in the numerical protection relays

requires a well-designed protection and information system, making

the best of the many different opportunities
