Issues to be considered before and after installation of electrical transmission line

 •            Well constructing a new transmission system is always a difficult task . For constructing or or extension of new transmission system we need to the factors and issues that would riase in the installation and after it as well.

We need to consider two factors before installation technical and economical .

• The technical include the power to be transmitted through the proposed line , length of the line.

• Nature of transmission either it is single circuit or double circuit.

• Voltage at which tower to be transmitted , nature of route from which the line will run .

Choosing the conductor material we consider weather ,temperature ,area and other environmental aspects. The nature of conductor play an important role in establishing a transmission line.

• The economic aspects include the loss per unit length , cost of auxilliaries .


    Factors that are considered After Installation of Electrical power transmission system • Choice of system voltage : 

         System voltage mostly used is high voltage either [HVDC HVAC] because for longer routes voltage or power may occur .

• Voltage Variations : This occurs due to many condition like weather changing voltage drop etc.

Reliability : System reliability is used after installation of transmission system so it can determine how much time this system will work.

• Load : After installing power transmission system load's capacity have an important role sometimes due to high overloading spark is generated in lines or due to increase in load the consumption of energy increases .

• So , load growth should be considered as a main factor because load means higher power used there.

Material Delay :Sometimes constructing power transmission system raw material can't be reached at the given time .

• Weather : Weather not remains same at all the time sometimes Rain ,cyclons,heatwaves,or any other natural disaster may occur.


Corona effect : It occurs due to due to the ionization of air and decomposition of fluids [Rain water or moisture on line]

• Also due to injury on conductor. • Indirect Emission :Energy losses during transmission can cause emission of carbondioxide and air pollution which effects health of living things.

Burning of transmission line: This occurs due to high voltage or any equipment mismanagement or due to short circuit.

• Biodiversity : The main effect is avian collision which is particularly significant at high risk areas such wood regions.

What is vector group of transformer?

Vector Group of Transformers                     • A vector group is the International Electrotechnical Commission (IEC) method of categorizing the high voltage (HV) windings and low voltage (LV) winding configurations of three-phase transformers.                      • Vector group is a connection of primary winding , secondary winding and an electrical angle difference .                      • The vector group designation indicates the windings configurations and the difference in phase angle between them. The three phase transformer windings can be connected several ways. Based on the windings’ connection, the vector group of the transformer is determined. •              The transformer vector group is indicated on the Name Plate of transformer by the manufacturer. The vector group indicates ...

Hosh Mohammed Sheedi

                 Sheedi , Hush Mohammed: The famous Surmo of Sindh and General Hoshu Sheedi, who chanted the slogan of 'Mursun Murson Sindh na Disson', have passed away during the Talpur period. Hoshu Sheedi , Talpur ruler Mir Fateh Ali Khan Talpur was an army soldier for military purposes. There have been several Anak soldiers in South India and Delhi Government. Alana, the renowned writer, writes the year 1801, the birth of Hoshu Sheedi. However, the birth of Seal Kathilvi Hoshu Sheedi is estimated in 1782 AD. According to William Napier, Hoshu learned the art of Tobacchi from the French armies, who were among the leading European subjects trained in various states of Mysore and Punjab, India during that period.                Hoshu Sheedi appeared in the court of Sindh in 1811. At that time the ruler of Sindh was Mir Fateh Ali Khan Talpur. Hoshu's son , Mir Fateh Ali Talpur's son Mir Subedar Ali and ...

Eclipses

What is Eclipse?  .                        When the light of the sun or the moon is obscured by another body the sun or moon is said to be in eclipse . Lunar Eclipse . When the earth comes between the sun , the shadow cast by the earth on the moon results in a lunar eclipse . Lunar eclipse  occurs only on a full moon day but not on every full moon day . Solar Eclipse . When the moon  comes between the sun and the earth , it causes obstruction of the sun's light when viewed from earth , and is called solar eclipse . A solar eclipse occurs on a new moon day when the moon is in line with the sun . However , solar eclipse does not occur on every new moon day .
