The deadline of 26th May 2023, for receipt of full papers must be strictly observed.
Final notification will be delivered to authors on 21st July 2023.
The electronic file is essential for publication. The maximum file size for uploading shallbe 2 M byte. (PDF format only)

1. GENERAL
1.1 Nature of Papers
Papers presented at CIGRE Colloquia must be unpublished material of strictly scientific ortechnical character, and not carry any advertising connotation. Consequently, names ofmanufacturers must not appear in the body of the text, nor in tables or figures. Names ofCompanies or Universities should only appear at the top of the first page (title page), under theauthors' names. (See paragraph 3.2) In case a product name is unavoidably used because thedescription would be complicated if the product name is not mentioned, the product name may
be mentioned only once.

1.2 Languages used
Papers are issued in English only.
2. STRUCTURE OF PAPERS
For homogeneity, the Paper structure with heading, “SUMMARY”, “KEYWORDS” and“BIBLIOGRAPHY” must be duly kept. The titles “SUMMARY”, “KEYWORDS” and“BIBLIOGRAPHY” also must be kept as they stand.
2.1 Heading
The heading comprises the Colloquium header, the paper number, the Study Committee,
Preferential Subject*, the title of the paper and the authors’ identification.
*PS should be determined from the three PSs listed in the Call for Papers and on the website. The
keywords are examples only; they are not necessarily indicators of PS categorization.
2.2 Summary
The paper starts with an extensive summary, of about 500 words, intended to provide readerswith a thorough overview of the paper.
Summary and title give the first impression of a paper; hence great care should be taken in theirformulation.
2.3 Keywords
A list of keywords follows the summary, as specified in Appendix 1. They are part of the title
page.
2.4 Main text.
To come after the keywords, and start at top of next page.
2.5 Bibliography
Included at the end of the paper, it gives the details of the references mentioned in the paper.

3. PRESENTATION OF PAPERS
Papers are to be posted on the Cigre website.
3.1 Typing: General
Texts should be typed in single spacing, and normal layout should be used (no 2-column layout).
- See sample: Appendix 3. There is no need for an extra left-hand margin, unnecessary waste ofspace. The text should be justified on both sides.
The fonts “Arial” ‘Times' or 'Helvetica' are recommended, size 11 or 12 only. Narrower typing
will be illegible. Do not use fancy characters.
ln order to simplify and speed up the editing of the Papers, CIGRE kindly requests theauthors to effect the lay-out of their Papers on a PC (with figures and tables inserted) on a ISO
21x29.7cm / DIN A4-format (final size).Please do not use other formats.
3.2 Title page, Summary and keywords
The authors are requested to use the provided sample page of the Title page. Its layout must bevery carefully observed. (spacing, fonts…).
The heading comprises three parts:- the header, CIGRE details and Colloquium title -provided by CIGRE on the sample page
- the paper number in seven digits, which has been attributed to the paper – to be typed by theauthor.
- the title of the Paper. For the authors: first names start with a capital letter and continue in lower
case, last names are written in CAPITAL letters only, company, country, and email address
for the main author. The main author must be indicated by an asterisk immediately following
his name. The maximum number of authors per paper is six.
Paper title should be typed 2” (5cm) from the top of the page with Helvetica or Arial boldcharacters, size 12. Authors can change the title of the full paper from the synopsis in order toaccurately represent the content. The authors’ names should be typed with Times Roman, boldcharacters, size 12. They should be centred under the title. The main author should be marked
with an "*". If there are multiple authors with the same affiliation, please list them together byaffiliation, separated by commas. The country should be written in one place only.
“SUMMARY” should be written ideally 4.8” (12cm) from the top of the page, under the“heading”.
3.3 Other pages
Pages other than title page must be typed starting 2.5 cm (1”) from the top of the page.
Pages other than the title page must be numbered at the bottom page (right hand side).
3.4 Bibliography
References should be mentioned following the order in which they appear in the text. Eachreference should be set as follows:- Reference number (in the text) in square brackets [ ]- First name(s) or initial(s), name(s) of the author(s)- Title of the article and in brackets the name of the publication, reference number, date, page (orfirst and last page numbers),

or- Title of the Paper, and in brackets the name of the relevant Conference, date, reference number
and page (or first and last page numbers)or- Title of the book, editor, year of publication and page (or first and last page numbers).
- Authors should not refer to internal company documents and more generally to unpublished.
3.5 Figures and Images
Electronic versions of the figures should be inserted directly in the text. They should be carefully
prepared.
Figure numbers and captions should appear under each figure. For better understanding, avoid
cramming information on figures and only use graphic symbols recommended by theInternational Electrotechnical Commission (IEC) Recommended Graphics Symbols – database
No 60617: 'Graphical Symbols for Diagrams' -.
All comments relevant to the figures should appear in the caption. Typing characters have to becarefully selected to ensure legibility. Images should be check as well to ensure a good resolution
while maintaining a reasonable size of the full Paper PDF file.
3.6 Tables
Typing characters should be chosen such as to be clearly legible. Table’s number and title should
appear just above the table.
3.7 Conformity requirements
All Papers must be prepared in keeping with the present instructions.
3.8 Length of Papers
The recommended maximum length for Papers is 10 pages (title and figures included).

4. ADVICE FOR LAY-OUT OF PAPERS- For greater clarity, texts should be divided under headings and subheadings. Decimals should
be used as reference numbers to identify chapters, sections, paragraphs.
- Authors are kindly requested to use the decimal metric system referred to as International System
SI (See IEC Publication No 60027 “Technical International standards for letter symbols in 6
parts). Some indications concerning symbols are given in Appendix 2.
- Authors should avoid giving mathematical developments. If these are necessary, the longer partshould be given in an appendix.
- For formulae, authors should use mathematical software. Equations should be centred on thepage and numbered. The number is to appear in brackets on the right hand side of the formula.

5. COPYRIGHTThe Papers are copyrighted to protect the interests of CIGRE as well as their authors’. Authors
who submit a paper for publication agree to assign to CIGRE the copyright in the paper, in
accordance with the “copyright provisions” exposed in Appendix 4.
6. PUBLICATION OF PAPERSAs Colloquium Papers will be available for downloading through the Cigre website, authors arekindly requested to upload the electronic file in PDF format to AMARYS.

APPENDIX 1
CHOICE OF THE KEYWORDS
A.1. Number of keywords
Authors have full latitude as regards choice and number of keywords. As an indication, 3 to 10
words or groups of words are usually sufficient to characterise a technical document.
A.2. Choice of keywords
1. Each keyword should correspond to a single and precise notion. Certain compound words orgroups of words designating one sole notion will constitute keywords.
Examples: High Voltage - Reactive Power - Power Factor
On the other hand, many compound words which are in fact an association of two independent
notions will have to appear as two separate keywords.
Examples:Interconnection systems -> Interconnection - System
Anchor tower -> Anchor - Tower
2. Words, which do not convey precise information, such as: product, matter, agent, effect,
process, device, phenomenon, etc...must not be used as keywords.
Examples: Breaking device -> Breaking
Corona effect -> Corona
However, with 'Switching Overvoltage' the keywords will be :'Switching' and 'Overvoltage'.
3. For the purpose of indexation, wherever possible, the noun in the singular should be used, rather
than the adjective.
Examples: Guyed tower -> Tower - Guy
Inhibited oil -> Oil - Inhibitor
4. A well-defined chemical substance is a single keyword.
Example: Sulphur Hexafluoride
However, chemical substance types should be coded with the help of independent keywords.
Example: Alcaline Chloride -> Chloride - Alcaline
A.3. Final comments
Keywords should always be written in singular, start with a capital letter, and a dash between
each word.
Authors are advised to use as keywords the terms which appear in the lEC's International
Electrotechnical Vocabulary (IEC Publication No 50).

APPENDIX 2
RECOMMENDATIONS ON THE SYMBOLS
WHICH SHOULD BE USED TO REPRESENT UNlTS
The SI symbols for units are typed with vertical characters, whatever the kind of characters usedin the text. They are written in small letters, except when the name of the unit comes from a name,in which case the first letter of the symbol is a capital one.
Examples:metre: m

volt: V

hertz: Hz

The products of two units are expressed by combining their symbols with a full stop.
Example:Newton metre: N.m

The symbols for single units can however be joined together without a full stop when there is norisk of confusion:
Examples: Watt-hour: Wh
kilovolt: kV

Volt ampere: VA
Megavar: Mvar

Write:HVDC or h.v.d.c.
DC or d.c.

HV or h.v.
AC or a.c.

The quotient of two units is expressed by putting a stroke between their symbols or by using
negative exponents, preferably when there are several symbols in the denominator.
Examples: metre per second: m/s or m.s–1
metre per second squared: m/s2 or m.s–2
The multiples and sub-multiples of SI units are linked to the basic units by standardised symbols
Examples:T for Tera (1012)

k for kilo (103)n for nano (10–9)

The prefix should not be separated from the name of the unit either by a space or any typographicalsign.
Thus, one should write:
GW: 109 watts
MHz: 106 hertz
kV: 103 volts
cm: 10–2 metres

mA: 10–3 amperes
μF: 10–6 farads
ns: 10–9 seconds

Symbols are written without a full stop (except when the full stop is a punctuation mark at theend of a sentence which finishes with a symbol) and must not bear the indication that they areplural because 's’ stands for ‘second'.
Examples: 100 kilometres: 100 km

1 metre per second: 1 m/s
1 lumen second: 1 lm.s
Symbols with decimal figures should appear at the right of the whole number, which indicates thenumerical value:
One should write: 24.5 m – 25.4°C
One should not write: 24 m.5 – 25°.4C nor °C25.4
Symbols for units should not be used after a number written out in full.
One should write:

Five kilometres
5 kilometres
5 km

One should not write: five km.
Generally speaking, it is not advisable to use a symbol for a unit in a text without it being
associated with a numerical value written in figures.
One should write:'Length is expressed in metres'
One should not write: ‘Length is expressed in m'

Normally, we check the corrosion state of steel tower members through visual inspection by
workers, and manage the location and level of the corrosion for each steel tower. As a result,
there are individual differences in judgments of the corrosion state, and a lot of time and labor
are required for prioritizing repair areas when formulating repair plans such as painting andreplacement of members.
To solve these problems, we developed a “Corrosion Diagnosis System.” The system consistsof an application for smart devices that allows users to take pictures and send data on-site, anda web cloud database that we can view
and manage at the office.
justified on both sides
We plan to improve the accuracy of corrosion level diagnosis by collecting additional training
data for the AI, and to update the database to make it easier for browsing by improving thesystem. In the future, we aim to achieve more efficient and effective planning of repair workand to maximize the life of facilities by implementing repair work at the appropriate time.
