Types of Cable Installation
Generally, the cable installation depends on the types of cable to be used and installation conditions. Here we will discuss the types of cable installation. There are two modes of…

Skin Effect
Skin effect is the tendency of alternating current (AC) to flow on the outer surface of the conductor. It especially takes place at a higher frequency. Skin refers to; current…
Continue readingFerranti Effect
Ferranti effect is prominent in medium or long transmission lines. When these lines are open-circuited at the receiving end or are under lightly loaded conditions then the receiving end voltage…
Continue readingWhat is Surge Impedance Loading?
Surge impedance loading or the natural loading of the line is defined as the load that can be delivered by a line having no resistance (loss-less line). Where the loading…
Continue readingWhat is Medium Transmission Line?
Transmission lines having lengths between 80 km and 200 km are medium transmission lines. They operate between 20 kV and 100 kV. The overhead transmission lines are classified as short,…
Continue readingWhat is Short Transmission Line?
Short transmission lines have lengths lesser than 80 km and operate on a voltage level lower than 20 kV. The overhead transmission lines are classified as short, medium, and long…
Continue readingCorona Power Loss
Corona power loss is the loss of power in the transmission line due to the corona effect. This power loss will affect the efficiency of the transmission line. But it…
Continue readingCorona in Transmission Line
Corona in the transmission line is evident for the voltage level of 100kV and above. When a potential difference is applied between two conductors separated by some distance. This causes…
