On 20th august, 2021, IEEE BUBT Student Branch organise a seminar on Everything you always wanted to know about high voltage Power lines
The speaker for the seminar was Mazana Armstrong, Senior Manager, High Power Lab and Powertech Lab.

The main theme of the seminar was providing the initial idea about high voltage Power Lines. It's a common application of the evolution of the power lines. She shows the high voltage application domain graph and power lines corner. Also, she shows the energy basis necessary for the economic development of a country. She described how to generate high voltage power and how to transmit that power. The high voltage power lines are also occasionally used to supply transmitting antennas, especially for efficient transmission of the long, medium, and short waves. For this purpose, a staggering array line is often used. Along a staggering array line, the conductor cables for the supply of the earth net of the transmitting antenna are attached on the exterior of a ring, while the conductor inside the ring is fastened to insulators leading to the high-voltage standing feeder of the antenna. Then she shows the sources of energy, energy consumption graph, and power factor (pf) issue graph and talks about the high voltage power lines that are usually considered to be 110 kV and above. Lower voltages, such as 66 kV and 33 kV, are usually considered sub-transmission voltages but are occasionally used on long lines with light loads. Voltages less than 33 kV are usually used for distribution. Voltages above 765 kV are considered extra high voltage and require different designs compared to equipment used at lower voltages. 

At the end of the seminar, Participants also asked their really effective questions. The participants learned more about high voltage energy production and transmission by high voltage power lines through this virtual seminar.
