Power system protection systems have three basic components: Instrument transformers, Relays, Circuit breakers
The function of the CT is to reproduce in its secondary winding a current I’ that is proportional to the primary current I. The CT converts primary currents in the kiloamp range to secondary currents in the 0–5 ampere range for convenience of measurement.
The function of the relay is to discriminate between normal operation and fault conditions. The OC relay in Figure 2 has an operating coil, which is connected to the CT secondary winding, and a set of contacts. When |I’| exceeds a specified ‘‘pickup’’ value, the operating coil causes the normally open contacts to close. When the relay contacts close, the trip coil of the circuit breaker is energized, which then causes the circuit breaker to open.
The book consists from the following sections:
1. Chapter 1: Power System Faults:
2. Chapter 2: Instrument Transformers.
3. Chapter 3: Overcurrent and Earth Fault Protection Relays.
4. Chapter 4: Radial System Protection.
5. Chapter 5: Zones of Protection.
6. Chapter 6: Differential Relays.
7. Chapter 7: Distance Relays.
8. Chapter 8: Transformer Protection.
9. Chapter 9: Generator Protection.
10. Chapter 10: Busbar Protection.
11. Chapter 11: Circuit Breakers.
12. Chapter 12: Fuses.
13. Chapter 13: References.

I am Dr. Hidaia Mahmood Mohamed Alassouli. I completed my PhD degree in Electrical Engineering from Czech Technical University by February 2003, and my M. Sc. degree in Electrical Engineering from Bahrain University by June 1995. I completed also one study year of most important courses in telecommunication and computer engineering courses in Islamic university in Gaza. So, I covered most important subjects in Electrical Engineering, Computer Engineering and Telecommunications Engineering during my study. My nationality is Palestinian from Gaza Strip.
I obtained a lot of certified courses in MCSE, SPSS, Cisco (CCNA), A+, Linux.
I worked as Electrical, Telecommunicating and Computer Engineer in a lot of institutions. I worked also as a computer networking administrator.
I had considerable undergraduate teaching experience in several types of courses in many universities. I handled teaching the most important subjects in Electrical and Telecommunication and Computer Engineering.
I could publish a lot of papers a top-tier journals and conference proceedings, besides I published a lot of books in Publishing and Distribution houses.
I wrote a lot of important Arabic articles on online news websites. I also have my own magazine website that I publish on it all my articles: http://www.anticorruption.000space.com
I am an Author publishing books on kdp.amazon.comand many other book stores such as Google, Apple.com, writinglife.kobo.com, Lulu.com, feiyr.com, blurb.com, bookrix.com, barnesandnoble.com, notionpress.com, ingramspark.com and others .
