In this chapter transmission line classification into short, medium, and long line is explained along with their equivalent circuits and phasor diagrams. Performance equations are derived. Receiving end values (or vice versa) is explained. Maximum power transfer for short lines is derived. Nominal T...
Electrical Parameters: The main electrical parameters of a transmission line are resistance, inductance, and capacitance. Performance of Transmission Line: The efficiency and voltage regulation are key indicators of a transmission line’s performance. There are three main types of Overhead Transmission L...

The Lightning Performance of Transmission Lines - ScienceDirect A significant number of faults in overhead transmission lines is due to lightning. Digital simulation has a very important role on predicting the lightning... W. DIESENDORF Dr. Techn. Sc. - Insulation Co-Ordination in High-Voltage ...
The IEEE Simplified Method [33] for computing lightning performance of overhead transmission lines was first described by Anderson [5]. Since its publication, considerable experience has been obtained in the application of the method and in the testing of various component models. This paper describe...

PDF Tools Share Abstract Service unavailability of transmission lines, due to the direct and indirect lightning strikes, is evaluated as a challenging issue within electric companies. The lightning event can produce dangerous overvoltage, equipment failures, and power supply interruptions. Here, externally...
S4d, which confirms that the film can significantly suppress THz transmission. To better reveal the optical properties of Te (100 nm) in the THz region, we have calculated the complex photoconductivity with the real part σ1 and imaginary part σ2 displayed in Fig. 2d under different ...
A multifocal metalens, which focuses incident light at multiple foci, has many applications in imaging systems and optical communications. However, the traditional design strategy of a multifocal metalens combines several lenses that have different focal points into a planar integrated unit, resulting in...
From simulations, ASE can be an early indicator of whether there is too much direct sunlight in a current design, which can be reduced by correcting window to wall ratio (WWR), adding shading devices, or reducing visible light transmission (VLT) of glazing. Daylight glare probability (DGP) ...
