Performance of Transmission Line

There are three main types of Overhead Transmission Lines: Short transmission line – The line length is up to 60 km and the line voltage is comparatively low less than 20KV. Medium transmission line – The line length is between 60 km to 160 km and the line voltage is between 20kV to 100kV. Long tran

Ground Clearance of Different Transmission Lines

Indian Electricity Rule 1956, Clause No 77, mentions, the minimum distance between bottom conductor and ground of different overhead transmission lines. As per Indian Electricity Rule 1956, Clause No 77, the minimum distance between bottom conductor and ground of a 400KV transmission line is 8.84 me

Surge Impedance Loading or SIL

Surge Impedance Loading is a very essential parameter when it comes to the study of power systems as it is used in the prediction of maximum loading capacity of transmission lines . However before understanding SIL , we first need to have an idea of what is Surge Impedance (Z s ). It can be defined

T Parameters: What Are They? (Examples Problems And How to Convert T Parameters to other Parameters)

What are T Parameters? T parameters are defined as transmission line parameters or ABCD parameters. In a two-port network , port-1 is considered as sending end and port-2 is considered as receiving end. In the network diagram below, port-1 terminMaster ABCD parameters—calculate T-parameters via open

Electrical Bus System and Electrical Substation Layout

There are many different electrical bus system schemes available but selection of a particular scheme depends upon the system voltage , position of substation in electrical power system, flexibility needed in system and cost to be expensed. The Main Criterias to be Considered During Selection of one

Electrical Power Substation Engineering and Layout

Electrical Substation Now days the electrical power demand is increasing very rapidly. For fulfilling these huge power demands the modern time requires creation of bigger and bigger power generating stations. These power generating stations may be hydro-electric, thermal or atomic. Depending upon th

High Voltage Direct Current Transmission | HVDC Transmission

The massive transmission of electricity in the form of DC over long distances by means of submarine cables or overhead transmission line is the high voltage direct current transmission. This type of transmission is preferred over HVAC transmission for very long distance when considering the cost, lo

Load Curve | Load Duration Curve | Daily Load Curve

Load Curve A graphical plot showing the variation in demand for energy of the consumers on a source of supply with respect to time is known as the load curve . If this curve is plotted over a time period of 24 hours, it is known as daily load curve . If its plotted for a week, month, or a year, then

Diversity Factor

We can not store electricity. Thus we have to generate electricity when it is required and as much it is required. The electrical source either it is generating station or substation or any other electric utility, has to fulfil the maximum demand of all connected loads to that source. But we are for

Why Do We Use 50 Hz or 60 Hz Frequency for Power Systems?

A power system is a network of electrical components that generate, transmit, and distribute electricity to end users. The power system operates at a certain frequency, which is the number of cycles per second of the alternating current (AC) voltage and current . The most common frequencies used for

Auto Reclosing Scheme of Transmission System

The extra high voltage transmission lines transmit huge amount of electric power . Hence, it is always desirable that the continuation of power flow through the lines should not be interrupted for a long time. There may be a temporary or permanent fault in the lines. Temporary faults get automatical
