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
