DESIGN AND PROTECTION OF OVERHEAD TRANSMISSION LINES, KPR Institute Engineering and Technology, Autonomous Engineering Institution, Coimbatore, India

The guest lecture on design and protection of overhead transmission lines discussed the following topics:
1. Design of overhead transmission lines
2. Design of electric protection system to detect and discriminate all faults on the protected line.
The participants gained knowledge on the above topics.

The department of Electrical and Electronics Engineering organized a guest lecture on “DESIGN AND PROTECTION OF OVERHEAD TRANSMISSION LINES” on 20/03/2023 exclusively for second and third year students of EEE. A heart-warming welcome was delivered by Dr. V. S. Chandrika, Professor, Dept. of EEE.
Dr. T. Hariharan, Assistant Engineer, Operation and Efficiency Division, Mettur Thermal Power Station/ TANGEDCO delivered a valuable presentation on design of transmission lines and protocols for the development of protection circuits for the same.
He had presented the discussions on
• AC circuits and sequence circuits of power networks
• Matrix methods in AC power system analysis
• Overhead transmission line parameters
• Modeling of transmission lines
• AC power-flow analysis using iterative methods
• Symmetrical and unsymmetrical faults
• Control of voltage and power flow
• Stability in AC networks
• High-voltage direct current (HVDC) transmission
• Corona and electric field effects of transmission lines
• Lightning performance of transmission lines
• Coordination of transmission line insulation
• Ampacity of overhead line conductors
The speaker covered everything electrical engineering students and practicing engineers need to know to effectively design the overhead power lines.
He also cleared all the queries of the participants in a detailed way.
The participants gave a very good feedback on the presentation of the speaker.
The   vote   of   thanks   was   delivered by Dr. C. Pazhanimuthu, AP (Sl.G)/ EEE. There were about 250 students and 20 faculty members attended the programme and got benefited. The department of EEE thanks the management for providing this opportunity to conduct the guest lecture successfully.
