Self-Calibration Method of Noncontact AC Voltage Measurement
Round 1
Reviewer 1 Report
In this paper, a self-calibration method for non-contact AC voltage measurement has been presented.
The paper seems to be interesting but, in my opinion, the quality of the presentation is too low. In details, Figures 1, 2, 3, 4, 6, 7, 9, and 10 are difficult to understand since they lack of node names and differentiations between conductive layers (capacitance plates).
I suggest a massive revision of the aforementioned images, using colors, legends, and, where possible, 3D color drawings. Without these preliminary changes, the manuscript cannot be revised properly.
Below some detailed indications for the Authors to improve the manuscript readability. Just the firsts 4 images are considered as examples, but the revisions from Authors have to consider all the abovementioned Figures.
1. In Fig. 1, I think that V0 is Vx.
2. In Fig. 2, the Transmission Line Ideal Model seems to be a coaxial cable, but it's not. I think it should be a structure similar to a triaxial cable.
3. In Fig. 3, where are the capacitances involved in the calculations?
4. In Fig. 4, it is impossible to understand how the probe is placed.
Conclusively, I recommand for the presented paper major revision.

Reviewer 2 Report
1. There is no quantitative performance reported in the abstract.
2. What are the required specification of the amplifier? refer to the analog circuit in Figure 10.

Reviewer 1 Report
Dear Authors,
thanks for properly revising the manuscript. The calculations and experiment performed are now correctly explained.
