Different Types of Overhead Conductor
In this post, we will explore about the different types of overhead conductors, like AAC, ACAR, ACSR and all aluminum alloy conductor (AAAC).
Transmission and Distribution
Kelvin's Law for Economic Choice of Conductor Size
Kelvin’s Law: The most economical size of a conductor for a transmission line is one where the annual interest and depreciation on the capital cost of the conductor are equal to the annual cost of energy loss due to the resistance of the conductor. Mathematically, this can be expressed as: Annual Cost of Energy Losses … Read more
Characteristics of High Voltage for Power Transmission Lines

Types of Transmission and Distribution Lines Based on their Primary and Secondary Roles
Primary Transmission Lines: Purpose: Primary transmission lines are the backbone of the electrical grid, responsible for carrying bulk electricity over long distances from power plants to substations. Voltage Levels: They operate at very high voltages, typically 66 kV (kilovolts) and above, to minimize energy losses during transmission. Construction: These lines are constructed using robust materials … Read more
