Opis

Presenting the theoretical principles for, and current state of, electrical power system protection engineering, this work explains the functions of protection and control equipment. It provides application guidelines for every component to be protected in a system, and examines and compares American, British and continental protection philosophies

Spis treści

Fundementals of protection engineering: the principal faults on electrical power systems and system components; the main criteria for detecting faults; instrument transformers for protection purposes. Analogue protection: solid state protection relays and systems; application of analogue protection devices; analogue protection for power systems; analogue protection for machines. Digital protection: computer-based protection and control; A/D conversion of input variables; digital signal conditioning; algorithms for digital protection; logical structures for digital protection. Appendices: symbols; characteristics of standard low-pass filters.
