Types of Faults in Power System
This article describes the different types of faults in power system, such as LLL, LL, LG, LLG, and LLLG faults. Faults are defects that cause … Read more
Symmetrical & Unsymmetrical Faults
Two common types of faults encountered in power systems are symmetrical and unsymmetrical, each with distinct characteristics and implications for system operation and protection. When … Read more
Symmetrical Components
The method of symmetrical components simplifies the analysis of unbalanced three-phase power systems under normal and abnormal conditions. This method simplifies the problems of unbalanced … Read more
Sequence Impedance
The sequence impedance of a power system is crucial in understanding how the system behaves under asymmetrical fault conditions. The system’s performance can be determined … Read more
Zero Sequence Current
Definition: An unbalanced current flows during an earth fault in an electrical circuit. This current is known as the zero sequence current or the DC component … Read more
