Electrical Earthing
Definition: Electrical earthing is the process of directly discharging electrical energy to the earth using low-resistance wire. This is done by connecting the equipment’s non-current-carrying part
Automatic Voltage Regulators (AVR) For Generator
Maintaining a constant voltage at different levels in a power system is crucial. Several techniques are available for voltage control at different levels. An Automatic
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
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
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
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
Phase Sequence
Definition: The phase sequence in a three-phase system shows the order of voltages attaining their peak or maximum value. The three phases in the 3-phase
Coefficient of Coupling – Definition, Formula, Derivation & Examples
Definition: The coefficient of coupling, denoted by (k), represents the proportion of magnetic flux generated by the current in one coil that interlinks with the
Skin Effect
Definition: The skin effect is a phenomenon in which alternating current (AC) does not uniformly distribute over the surface of the conductor, and it is
Inrush Current
Inrush current is the peak or maximum current that an electrical circuit draws when turned on. It can last for 3 to 10 cycles of
