To develop the empirical formula to determine the Corona loss occurring in EHV AC transmission File Size: 1MB. For EHV and UHV transmission lines the switching overvoltages become the limit­ing factor in the design of insulation levels and arrester characteristics.

Once the line is designed adequately against switching overvoltages, it is capable of encountering temporary overvoltages. Electrical Transmission Networks and Overhead Lines Generally, EHV and HV (High Voltage; 60 kV ≤ VEHV: Extra High Voltage; V ≥ kV) is used for energy transmission to decrease the current in the line, what allows the reduction of the cross section of conductors and losses by Joule effect (Joule law: W = RxI 2 xt = UxIxt, where “ t ” is the time).

The course emphasizes learning and understanding the newer design criteria required for the UHV transmission systems viz: insulation design, protections, safety concerns etc. The course starts with an introduction to the importance of EHV /UHV transmission, its present and future growth.

Common Configuration of EHV/EHV and EHV/HV Substations. EHV/EHV and EHV/HV substations may have several configurations (topologies), depending on the requirements of the continuity, the reliability and the quality of power supply.

The same substation may have more than one type of configurations, depending of the voltage levels. Book Description.

OHLELECT AND MECH. This article covers information about the health diagnostic methods, as well as about preventive and predictive maintenance techniques in cold line and in hot line conditions Maintenance of transmission linesThe transmission lines play a very important role in transmitting the huge quantum of electrical power generated at various generating stations to the whole area of [ ].

In UHV Transmission Technology, Selection of OPGW Common Structures. Optical fiber ground wires (OPGWs) are installed above the conductors of transmission lines to act as lightning wires of transmission lines such that, in case of any lighting strikes, they can expose them to the lightning strikes, thereby protecting the conductors.

Overhead Transmission Lines are expected to withstand climatic conditions and other outside disturbances. The applied forces must be tolerated mechanically by structural components of Transmission Line.

Transmission Line must not fail in the hardest. The design of a transmission line has to satisfy electrical as well as mechanical considerations. An overhead line comprises mainly of conductors, line supports, insulators, and pole fittings. These should have sufficient mechanical strength to withstand the worst probable weather conditions and other external interferences.
