Protection Techniques in Electrical Energy Systems

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.
