Round 1

Reviewer 1 Report

Effective description of degradation processes and visual examples in the beginning of the manuscript followed by documentation of results. Results include a vast assessment of samples. However, the manuscript finishes rather abruptly and simply states that the maximum lifetime of porcelain insulators in the case of Korea is predicted to be approximately 40 years.

The message of the paper is that geographical environment affects corrosion more than the served lifetime. This is clear. This is shown by providing pH values of investigated regions and displaying condition of collected insulator samples. However, how was this used to calculate the lifetime of the insulators to come up with the 40 year lifetime statement for Korea? The years of service given in table 1, are these values end-of-lifetime or have the samples taken out of service for this research (while still being fit for continued service)?

The results are clearly presented, but I would ask the authors to make a clearer connection to the given conclusions. This would improve the interest of the paper to other readers who could use the same methodology to assess their insulators.

The English language is good. Only minor editing needed:

line 46: Indentation.

line 81: “PH” = pH

line 101: Capitalization of header

line 111, 113: check spacing after period

line 120: capitalization of header

Line 167: Should Figure 7 be sourced in references rather than figure caption?

Line 170: Winter = winter

Figure 8, in final version, ensure figure placement does not overlap between pages

References: check formatting and fonts (some are all capitalized, and transactions abbreviated while others are different).
