The part on the distribution of dips during the day and during the year is interesting and new. This part, however, should be more statistically justified (e.g., what is the statistical basis for the trendline in fig. 9?). To have a good paper, it would be interesting to discuss the observations (why do more interruptions occur in winter months?). 2) The references list is very outdated and does not give the impression that the author is aware of the current state of Power Quality research. Reference 1, 3 and 4 seem to be too technical detailed for the current paper. Small remarks Pg2: the author states that there are 2 approaches to tackle PQ-problems. Why does the author not consider to adapt the electricity grid in a way that less disturbances occur as an option? Pg4, figure4: The caption states “short interruption of an MV customer” . This could also be a long interruption and the voltage level suggests LV. Pg6: The author states that the monitoring campaign represents the pq-level of the entire medium voltage. Could you prove this statistically, since you only measure 200 out of the 2800 customers. General conclusion : the paper is interesting, but should only be considered with major modifications

So we restart the review cycle, requesting David for a brief check of version 2. Based on David’s review, a new version of this paper has been received and uploaded (see above post).

It shows an application of 2 different comunication protocols, KNX and Lonworks namelly, for monitoring use. It depicts measurement results and analyzes the advantages and drawbacks. Therefore, I recommend the publication of this article in the EPQU Magazine. this article is fits in the EPQU Magazine perfectlly.

It does not have much substance or focus. It talks about the need to harmonize standards for quality between the UCTE and Russian power system but it is all quite superficial.
