Topic

Other / unclassifiable — a classification, not a measurement. An on-box language model (Qwen3.6-35B-A3B-FP8, prompt version 1) read this channel’s own recent posts on 19 September 2026 and assigned it the closest of 31 fixed categories, at 55% confidence. This is a model’s judgement about what the channel is likely to be about, not a fact this register measured the way a subscriber count or a view count is measured — it can be revised on a later pass, and it carries no weight anywhere else on this page. How this classification works, and why it has no browse page of its own yet.

8 measurements spanning 33 days, net +152. Dots are measurements; the straight line between them is drawn to join them, not to claim we know the path taken in between — snapshots are recorded only when a count changes, so gaps mean “no change observed”, never “interpolated”. The vertical axis spans 2,943–3,141 and does not start at zero.

Engagement

20 posts held, back to 26 November 2025 — the reader has not yet reached the start of this channel’s public history, so older posts may sit further back, unread. Read across 1 page of Telegram’s post history, 20 posts per page.

Nothing published in the last 30 days. ERR and ER are rolling 30-day measures, so there is nothing to compute — we hold 20 posts for this entry, the most recent from 30 August 2026. An engagement rate over an empty window would be a number about nothing.

What this channel posts

Video runtime
34s
Average length
17s

Measured directly from 2 videos with a duration reading, out of the posts we hold for this channel — not this channel’s whole posting history, only the sample this register has actually read. An exact reading to the second, taken from the post itself rather than from Telegram’s own rounded chrome, so it carries no ≈ mark.

Reaction mix

140 reactions across 17 posts, in 3 distinct kinds. The most used accounts for 50.7% of them.

Every reaction kind recorded on the sample, most used first
ReactionCountShareShare, drawn
❤7150.7%
👍6747.9%
🙏21.43%

No sentiment is inferred, and none should be read in. This table is ordered by count and by nothing else. Emoji do not carry stable meaning across languages or communities — 🙏 is thanks in one channel and mourning in another — so we publish which ones were pressed and how often, and pass no judgement on what an audience meant by them.

Precision. Telegram publishes reaction counts per emoji and short-forms each one — 4.34K, 1.2M — so any single kind at or above 1,000 reaches us at three significant figures, and only counts below 1,000 are exact. The shares above are ratios of those figures and carry the same error. This is also why the total here can differ slightly from a reaction total printed elsewhere on the page: both are sums of the same rounded parts, taken over samples with different edges.

Coverage. Reactions were read on 17 of the 20 sampled posts in this sample. Summed by Telegram’s own count on each post — not by adding up the per-emoji breakdown above — those same posts carry 140 reactions in total: the kind of figure the paragraph above means by “a reaction total printed elsewhere on the page”.

Measured over the 20 most recent posts we hold, published 26 November 2025 to 30 August 2026, using the newest reading held for each. Telegram Stars are excluded: they are a payment, not a reaction, and they have their own section.

اسکیم Permissive Overreaching Transfer Trip (POTT) یک اسکیم حفاظتی می باشد که برای حفاظت خطوط کوتاه استفاده می گردد. در این اسکیم اگر رله خطا را در زون ۲ خود دیده باشد و همزمان نیز سیگنال permit از سمت دیگر خط دریافت کند رله زمان عملکرد زون ۲ خود را آنی می کند و برای بریکر یا بریکرهای مربوط به خود فرمان تریپ صادر می کند. همچنین همزمان با دیدن خطا در زون ۲ خود نیز سیگنال permit برای طرف دیگر خط ارسال می کند و به طور…

تفاوت سیگنال‌های VT Fuse Fail و VT MCB Fail 🔹 VT Fuse Fail این سیگنال زمانی فعال می‌شود که در مدار ثانویه CVT از فیوز استفاده شده باشد و فیوز دچار سوختگی شود، یا در صورت استفاده از MCB، به دلیل شل بودن اتصالات (Loose Connection) در مدار ثانویه، ولتاژ یکی از فازها کاهش یافته یا به صفر برسد. در این حالت، رله با استفاده از الگوریتم داخلی خود، مشکل را شناسایی کرده و آن را از خطاهای واقعی تفکیک می‌کند. 🔹 VT MCB Fail در …

فلسفه انتخاب زون‌های ۱ و ۲ در حفاظت دیستانس ۱. چرا زون ۱ معمولاً روی ۱۰۰٪ خط تنظیم نمی‌شود؟ در حفاظت دیستانس، معمولاً زون ۱ روی ۱۰۰٪ امپدانس خط تنظیم نمی‌شود. دلیل این موضوع وجود خطاهای اندازه‌گیری و محاسباتی ناشی از CT، VT/CVT، رله، مقاومت خطا، مدل‌سازی شبکه و سایر عوامل است. این خطاها می‌توانند باعث شوند امپدانس دیده‌شده توسط رله تا حدود ±۲۰٪ با مقدار واقعی اختلاف داشته باشد. ۲. علت انتخاب ۸۰٪ برای زون ۱ به همین د…

نکته مهم در نرم‌افزار ABB CAP 505 📌 بسیاری از رله‌های ABB مانند سری REF54 و REM54 با نرم‌افزار CAP 505 تنظیم و پیکربندی می‌شوند. یکی از اشتباهات رایج کاربران این است که پس از اعمال تغییرات در رله، عملیات Store را انجام نمی‌دهند. در CAP 505 پس از پایان تنظیمات، از مسیر زیر گزینه Store را اجرا کنید: Transfers → Store با این کار تنظیمات در حافظه دائمی رله ذخیره می‌شود. ⚠️ اگر Store انجام نشود، با قطع و وصل تغذیه رله، تن…

مفهوم C/k در رله Novar 300 این پارامتر نسبت جریان خازنیِ ناشی از کوچک‌ترین پله خازنی به جریان نامی ثانویه CT را در این رله بیان می کند. یعنی رله با C/k تشخیص می‌دهد وقتی کوچکترین پله خازنی وارد مدار شود، چه مقدار تغییر جریان راکتیو روی ورودی جریان رله دیده می‌شود. رله با این عدد می‌تواند تشخیص دهد: ➡️این تغییر، ناشی از یک پله خازنی است نه نوسان بار یا نویز شبکه اگرCT بزرگ‌تر انتخاب شود و یا پله اول خیلی کوچک باشد:…

Showing the 12 most recent of 20 posts we hold for @ProtectionEngineering. View and reaction counts are the latest single reading for each post, not a live figure, and a recent post is still accumulating both. A view count marked ≈ was rounded by Telegram before we ever saw it — t.me prints views in full below 1,000 and to three significant figures above, so ≈1,200,000 means somewhere between 1,150,000 and 1,249,999. Unmarked counts are exact. Text is reproduced from the public post preview and truncated for length.

Forward network

Republished by

Channels on the register that have forwarded this channel's posts into their own feed.

Republishes

Channels on the register whose posts this channel has forwarded.

Built only from forwarded posts we have actually read, on both sides. Coverage is early and deliberately incomplete: a missing link means we have not read the post that would prove it, never that the relationship does not exist. Counts are distinct forwarded posts observed, so they only ever go up as we read more.

Mentions

Named by 1 registered channel — every channel on the register whose own posts have named this one, by its current username or any other username it currently holds, merged from two separately captured readings of the same fact so a namer caught by only one of them is not missed and a namer both caught is not counted twice. A username this channel has since dropped is not matched — that handle may belong to someone else now, and crediting today’s namer to yesterday’s owner would misattribute it.

Named by

Channels on the register whose posts name this channel's handle.

Names

Channels on the register whose handles appear in this channel's posts.

A mention is a weaker signal than a forward and is counted separately for that reason — naming a channel is not republishing it, and a handle in a post body is easy to place deliberately. The post counts beside each row below are distinct posts in which the handle appeared, from posts we have read on both sides — the “Named by N registered channels” figure above is a different count, of distinct NAMING CHANNELS rather than posts, and is not the sum of the rows under it.
