Comments and Suggestions for Authors

I have listed few of my concerns on this paper:
1. In the result section, you have presented the screenshots of results and is in dark background.

2.Please save the image in white background to make it clear and better with notation for x-axis and y-axis.
3. The references cited is not up-to-date. Please make proper comparison and analysis between the recent literatures.
4. Rewrite the abstract to better demonstrate the problem and solution you have presented in this paper.
5. Please check for language and grammatical issues.
6. Please make proper discussion of the results.
7. Please include the limitation to proposed method also.
8. Please present a clear future direction in the conclusion section.
9. Please present the real world scenario, how can this model be applied.

Reviewer 2 Report

Comments and Suggestions for Authors

Abstract: While informative, it lacks specificity in terms of the achieved results. Can the authors provide quantitative outcomes or improvements over existing methods?

Introduction: The introduction extensively discusses the general importance of digitalization in power systems. Could the authors reduce the general background and focus more on the unique aspects of their proposed system?

 

1.     The paper briefly mentions different modulation techniques (e.g., FSK, PSK, PAM) but does not provide a strong justification for choosing FSK for the final implementation. Could the authors elaborate on why FSK is preferred over other options, considering factors like interference immunity and operational efficiency?

2.     How scalable is the proposed system to higher voltage levels or larger networks? Are there constraints or challenges for real-world deployment that were not discussed in the paper?

3.     Have the authors considered the reliability of wireless transmission in areas with high electromagnetic interference, such as industrial zones?

4.     The methodology involves simulations, but no physical experimental validation of the proposed system is included. Are there any plans for real-world testing? If not, how confident are the authors in the system's performance in practical scenarios?

5.     Some diagrams (e.g., Figures 10 and 11) could benefit from additional explanations in the captions. For example, what are the specific roles of the INA226 microcircuit in ensuring accurate data transmission?

6.     Including metrics like system latency, energy consumption, or reliability under various noise conditions would enhance the paper's depth.

7.     Adding a case study or hypothetical scenario where the system is deployed would make the paper more relatable to practitioners.

8.     A comparison of the proposed system with existing technologies (e.g., SCADA systems) would highlight its advantages and limitations.

The paper presents a digital system for monitoring single-phase earth fault conditions at medium voltages, including 20 kV. This system combines digital units for induced stress measurement and an information network to detect ground failures. Wireless technologies are used, and simulation results are used to select suitable technology. A digital radio channel model and programmable microcontroller project are also proposed.

Following are my comments:

      1. The obtained results should be compared to existing data to identify any discrepancies  or areas for improvement.

2. What specific algorithms are used for fault detection and localization in the proposed system? What are the key parameters monitored by the zero-sequence sensor, and how are they processed?
3. How does the system handle variations in load and other dynamic conditions in the network?
4. How does the system account for noise and interference in the wireless communication channels? Can you provide details on the calibration process for the digital units and sensors?
5. Does the system ensure synchronization between different measurement nodes? What are the statistical methods used to analyze the data collected from the sensors?
6. How does the system ensure data redundancy and reliability in case of sensor failure?
7. What are the potential environmental factors that could affect the system’s accuracy and reliability? How does the system perform under extreme weather conditions, such as high humidity or temperature variations?
