Choice of the Optimum Cross-Sections for 20-110-330 KV overhead Lines under Market Conditions

An approach is proposed to the choice of overhead line cross-sections that would be optimal under market conditions. For this purpose, in the design practice and at network reconstruction two methods exist: of the economic current density, and of the ...
