Foundation of any structure plays an important role in safety and satisfactory performance of the structure as it transmits mechanical loads of the electrical transmission system to earth. A transmission structure Without having a sound and safe foundation, it cannot perform the functions for which it has been designed. The foundations in various types of soils have to be designed to suit the soil conditions of particular type.In addition to foundations of normal towers, there are situations whe

There are four main methods of the erection of steel transmission towers which are described below: Build-up method or Piecemeal method. Section method. Ground assembly method. Helicopter method.Build Up Method of Transmission Tower ErectionThis method is most commonly used in India for the erection of 6.6 kV, 132 kV, 220 kV, and 400 kV transmission line towers due to the following advantages : Tower materials can be supplied to the site in a knocked down conditions which facilitates easier and

What is a Transmission Tower?A transmission tower (also known as a power transmission tower, power tower, or electricity pylon) is a tall structure (usually a steel lattice tower) used to support an overhead power line. In electrical grids, they are used to carry high voltage transmission lines that transport bulk electric power from generating stations to electrical substations; utility poles are used to support lower-voltage sub-transmission and distribution lines that transport power from sub

Formation of Bus Admittance Matrix (Ybus)S1, S2, S3 are net complex power injections into bus 1, 2, 3 respectivelyy12, y23, y13 are line admittances between lines 1-2, 2-3, 1-3y01sh/2, y02sh/2, y03sh/2 are half-line charging admittance between lines 1-2, 1-3 and 2-3The half-line charging admittances connected to the same bus are at same potential and thus can be combined into oneIf we apply KCL at bus 1, we haveWhere, V1, V2, V3 are voltage values at bus 1, 2, 3 respectivelyWhere,Similarly by ap

Reason of Transmission Line InductanceGenerally, electric power is transmitted through the transmission line with AC high voltage and current. High valued alternating current while flowing through the conductor sets up magnetic flux of high strength with alternating nature. This high valued alternating magnetic flux makes a linkage with other adjacent conductors parallel to the main conductor. Flux linkage in a conductor happens internally and externally. Internally flux linkage is due to self-c

Flexible AC Transmission Systems (FACTS) – What and why?FACTS is the acronym for “Flexible AC Transmission Systems” and refers to a group of resources used to overcome certain limitations in the static and dynamic transmission capacity of electrical networks. The IEEE defines FACTS as alternating current transmission systems incorporating power-electronics based and other static controllers to enhance control ability and power transfer ability. The main purpose of these systems is to supply the

Tariff refers to the amount of money the consumer has to pay for making the power available to them at their homes. Tariff system takes into account various factors to calculate the total cost of the electricity.Before understanding tariff of electricity system in detail, a slight overview of the entire power system structure and hierarchy in India would be very fruitful. The electrical power system mainly consists of generation, transmission and distribution. For generation of electrical power

At first we have to know about power stability study. Stability study is the procedure for deciding the stability of a system upon some disturbances and this is followed by several switching actions (ON and OFF). In the power system, the behavior of synchronous machine can have some impacts due to these disturbances. The evaluation of this impact in the stability studies are transient stability studies and steady state stability studies. The steady state stability study refers to whether the syn

It is the computational procedure (numerical algorithms) required to determine the steady state operating characteristics of a power system network from the given line data and bus data.Things you must know about load flow: Load flowstudy is the steady state analysis of power system network. Load flow study determines the operating state of the system for a given loading. Load flow solves a set of simultaneous non linear algebraic power equations for the two unknown variables (|V| and ∠δ ) at ea

Corona Discharge, also referred to as the Corona Effect, is an electrical discharge phenomenon that occurs when a conductor carrying high voltage ionizes the surrounding fluid, often air. The corona effect will occur in high-voltage systems unless sufficient care is taken to limit the strength of the surrounding electric field.It’s since corona discharge involves a loss of energy, engineers seek to reduce corona discharge to minimize electrical power loss, production of ozone gas, and radio inte
