Round 1
Reviewer 1 Report
This paper describes a thermal modeling work for multicolumn parallel zinc oxide arresters under extreme operating conditions. The simulation model show advantages over previous ones and the calculation results have been validated by field test. The work is novel and solid, providing guidelines for researchers in this field. The writing is also clear and easy to follow. I support the acceptance of this paper.

Reviewer 2 Report
The article is very interesting and scientifically significant.
Could authors describe and show the simulation models in PSCAD software?
Could authors explain the difference between f2 and f4 failure?
Could authors provide the characteristics of surge arresters according to IEC 60099-4: Rated voltages (Ur), Nominal discharge current, Repetitive charge transfer rating, Qrs, Thermal energy rating, Wth, Single impulse energy capability….

Reviewer 3 Report
Authors performed a computational simulation for understanding the thermal behaviors of parallel arresters in a multicolumn case. The study is in the scope of the journal and the given methodology clearly touched the motivation. The study can be published in this journal after pointing out some minor concerns, most of them related to the figure qualities:
1) The literature review is weak, please strengthen the literature section with more references, especially in computational simulations.
2) The computational domain is correct but please also provide a mesh view in Figure 1.
3) Resolution of Figure 3 should be improved.
4) From Figure 4 to 18, authors are strongly encouraged to increase the font size of numeric values in the figures and white background instead of the default background of ANSYS Fluent environment.
5) Conclusion should be strengthened with a clearer definition on the future works.
6) A final paragraph can be added to the end of Section 6. Main limitations and constraints of the experimental test rig and the computational simulation should be mentioned.

Reviewer 4 Report
Comments:
The title is interesting. “Thermal Characteristic Simulation Study of Multicolumn Parallel Zinc Oxide Arresters Under Extreme Operating Conditions”. The authors aimed to study the thermal characteristics of multicolumn parallel arresters under extreme work operation. However, in the present form, there are significant issues that need to be done. For improving the quality of the paper, the authors can address the following comments:
1. In the abstract, perhaps the Authors need to add one or two sentences as background about the problem leading to this study.
2. In the abstract, the authors mentioned that the simulation data matches well with the field-test data. The reviewer believed that that is not enough significance or contribution for this study. Please include other contributions to this study. What about the thermal characteristics findings?
3. In the introduction literature review is important. The paper literature review is too short and no enough discussion on the previous references such as in [12-15], [18-20], [21-25]. Authors can improve the literature review by including more details about previous studies and comparisons.
4. In Tables 2, 3 the authors need to mention the parameter values obtained from or include references.
5. The simulation and field test data are matching, How do the authors explain the field arrester is under extreme operation? Can authors include any report from Niu Zhai station about the condition of the tested arrester? Authors can highlight their explanation in the revised paper if it is included.
6. The conclusion is too detailed.
7. In References, looks there is no diversity of reference sources.
