Salman S. Digital Protection for Power Systems 2ed 2022

Textbook in PDF format

Electric power systems have become much more complex in the past years, owed to distributed generation and the intermittency of renewables. This complexity makes power systems potentially more vulnerable. However, use of information technology also helps in detecting errors and problems, and in preventing and correcting them.
