Power Frequency Overvoltages in Power Systems: The Power Frequency Overvoltages occur in large power systems and they are of much concern in EHV systems, i.e. systems of 400 kV and…
Switching Surges in Transmission Line: Till the time when the transmission voltages were about 220 kV and below, over-voltages due to lightning were of very high order and overvoltages generated…
Transmission of Waves at Transition Points: Whenever there is an abrupt change in the parameters of a transmission line, such as an open circuit or a termination, the travelling wave…
Attenuation and Distortion of Travelling Waves: As a Travelling Waves moves along a line, it suffers both attenuation and distortion. The decrease in the magnitude of the wave as it…
Classification of Transmission Lines: Classification of Transmission Lines are usually classified as Lines with no loss or ideal lines, Lines without distortion or distortion less lines Lines with small losses,…
Mathematical Model of Lightning Stroke: During the charge formation process, the cloud may be considered to be a nonconductor. Hence, various potentials may be assumed at different parts of the…
Parameters and Characteristics of Lightning Strokes: The parameters and Characteristics of Lightning Strokes include the amplitude of the currents, the rate of rise, the probability distribution of the above, and…
Lightning Stroke Definition | Mechanism of Lightning Strokes: Lightning Stroke Definition explains that when the electric field intensity at some point in the charge concentrated cloud exceeds the breakdown value…
