Reviewers' comments:


Reviewer #1: The paper could have been interesting from an engineering standpoint chiefly for those Countries that have territory resources and no problems to erect new overhead lines.
1.        Such a number of mistakes and anacolutha renders the paper almost unreadable. The authors ought to perform a complete revision of the text.
2.        From a technical standpoint, it is necessary to write that the circuits of the overhead lines are in electrical parallel otherwise all the research of the authors is meaningless (as it has been demonstrated in the paper Benato, R.; Dambone Sessa, S.; Guglielmi, F. Determination of Steady-State and Faulty Regimes of Overhead Lines by Means of Multiconductor Cell Analysis (MCA). Energies 2012, 5, 2771-2793).
3.        Also the title has grave mistakes. I propose to modify it with:
Research on the unbalance degree of four-circuit overhead lines on the same tower with different phase sequence arrangements .
4.        The text is strewn with grave mistakes; only some of the worst ones:
1）CASSON theory is CARSON theory
2）All the complex numbers must be underlined
3) Self and mutual impedances and not self and mutual impedance factors.
4) Reference 2 Oberto is Roberto.
5) Symmetry parameter and not parameter symmetry
6) Head of the line is sending-end and the end of the line is the receiving-end.
5.        In the highlights:
The basic evaluation index of parameter symmetry has been definite …has two grave mistakes
It should be: The basic evaluation index of symmetry parameter has been defined
Moreover, a very similar paper has been published in Electrical Power and Energy Systems 85 (2017) 67-76 entitled Research on the electric unbalance degree of multiple transmission lines non-parallelly erected entirely in one common corridor by Jun Zhu , Guangning Wu, Chaoqun Shi , Degang Gan, Yongxing Cao, Chi Wu and does not appear in the reference section.

Reviewer #2: In my opinion, the paper number 1392, in the present form is not yet suitable to be published in ESPR journal. However, I believe that the subject may be largely improved becoming of interest. Thus, I would suggest the Authors to proceed in their work, improving the contribution in terms of both reference list and language. 返回小木虫查看更多
