発酵器の製作

毎年4月下旬から5月上旬にかけては新茶収穫のシーズンで、自家消費する1年分の乾燥茶葉をこの期間に製造している（激務）。最近は加工プロセスを変えながら、煎茶のみならずいろいろなタイプの茶を作っているが、こと紅茶についてはこの時季の当地の気温が本発酵工程に必要とされる雰囲気温度に満たない為、適度に加温することで発酵を促進し、より香り高い紅茶を作りたいところである。

まずは既存の所有機器の利用を考える。ホームベーカリーには生地の発酵モードがあり流用できそうにも思ったが、生茶葉を入れるにはいかんせん容量が小さい。古い電気炊飯器は容量はデカイが保温モードでも加熱温度が高すぎるだろう。

身の回りに適用できそうなものもないので、都合良い商品がないかインターネットで調べる。発酵器で検索すると多用途可能な物から特定用途のものまで様々有り、グレードも値段もピンキリだ。う～む、複雑な機能はいらないので、そこそこの収納容量があって温い温度を維持できるリーズナブルな製品はないものか。。。いろいろ探し回った結果、部品を買って自分で作ってやろうと相成った。

まずは加温する為のヒーター。そんなに熱くする必要は無く、爬虫類飼育用のパネルヒーター（上の写真左）を調達した。サイズは28cm×28cmで消費電力は28W。ボリュームで出力強度が変えられることや、それなりに防水性があるのも有難い仕様だ。価格は1900円。

そして一定の温度になるよう制御するためのコントローラー（上の写真右）。基本的に2つの設定温度間でON-OFF制御するだけの物だが、温度センサーも付いて1000円は安いと思う。AC100V駆動タイプなのでAC/DCアダプターも不要だし、直接出力方式なのも簡単で良い。

スーパーマーケットで貰った発泡スチロール箱（無料）の内部にパネルヒーターを敷き、給電コードを箱の外側まで引き出す。逆に温度コントローラーの温度センサーは箱内部に引き入れる。

温度コントローラーは箱の外側に取り付け、その出力コードをヒーターと接続する。次に給電コードをコンセントに接続するとLEDパネルに現在の測定温度が表示されるので、出力ONとOFFの温度をそれぞれ仮設定してヒーター制御が正しく機能するかをテストする。結果問題無し。

発酵プロセスにどれだけの時間を掛けるかは仕上がりに影響する重要な要素である。なので温度コントローラーの給電をダイヤルタイマー経由にして所定時間経過後に自動で加温制御を停止させる。このダイヤルタイマーはもう30年ほど前に購入した物で、最近その存在を思い出し押入から引っ張り出して液体蚊取り器の自動停止に利用していた。まだまだ現役だね（笑）。

発酵容器はアルミ製の鍋を流用。内径33cmの大きさは我が家のガステーブルでは使いづらく、数年戸棚の奥で眠っていたが、平らな鍋底とその広さがヒーターのサイズに抜群にフィットしたのと、15cmの高さが蓋をした状態でこの発泡スチロール箱に丁度収まったため採用となった。伝熱性も申し分無いだろう。

底部から加温するため、側面は放熱緩和のためアルミ保温シートを巻いた。

制御部も発酵容器も準備が整ったので、発酵させる茶葉を入れていく。ちなみにこの茶葉は収穫後20時間ほど軒下に吊し萎調させた後、手で揉捻して発酵しやすく処理した物。温度センサーは写真では茶葉の上にあるが、実際には茶葉の内部に突っ込んだ。

上部からの放熱も緩和するためアルミ保温シートを挟んでから鍋蓋を置いた。

発布スチロール箱の蓋も閉めたらダイヤルタイマーを回して加温制御をスタートする。

実際に茶葉を入れての最初の運転なので、温度がどのように変化するかLED表示を逐一観察した。ヒーターは最大出力設定で、停止温度は28℃の設定。スタートからじわりじわりと温度が上がっていくが、あるところから急に上昇スピードが増す。停止設定温度に達してヒーター出力はOFFになるもそのまま温度は上がり続け、さらに4℃ほど上がったところで落ち着いた。その後の温度下降はとてもゆっくりで、再びヒーターがON出力されるまでにはかなりの時間が経過した。ただ二度目は最初ほどの温度上昇に至らずに温度制御するようになった。これは最初の想定とは違っていたが、適温に至った時点で茶葉の発酵が一気に活発になって自己発熱が始まり、ある程度発酵が進むと発熱も終息するということが起こった結果だと推測した。

4時間後、ダイヤルタイマーが停止設定時間に達し加温制御が停止したため、蓋を開け茶葉の状態を確認する。先の状態と比較すれば多くの茶葉が赤褐色に変化し発酵が進んだことが伺える。ただこれが最終的にどのような品質の紅茶になるかは製茶してみないとわからないし、どのような制御を掛けると理想的な品質になるかは今後設定をいろいろ変えて見極めていかなければならない。ちなみに可変要素は以下のようなところか。

・温度測定点（温度センサーの設置場所） 　　容器底／容器側面／茶葉内／茶葉上／容器空隙 ・制御温度（コントローラーの設定） 　　ヒーターOFFおよびON温度 ・ヒーター出力強度（ボリュームで設定） 　　高／中／低 ・加熱制御時間 　　2～6時間 ・容器の保温性 　　高／低 ・前処理との関係

毎年製茶作業は実質2週間ほど行うが、そのうち紅茶は3日程度なので試行錯誤に数年は掛かりそうだ。まあ焦らず気長に取り組んで参ります（苦笑）。その間に何か他の物の発酵に利用するかも知れないけど。

Cybersecurity in Power Systems:  Safeguarding Transmission and Distribution Infrastructure

Introduction:

In an era dominated by technology, the power industry is undergoing a transformation, with the integration of smart grids and digital solutions becoming increasingly prevalent.  However, this digital evolution brings with it a new set of challenges, particularly in the realm of cybersecurity.  Power systems, including transmission and distribution infrastructure, are critical components of our modern society, making them prime targets for cyber threats.  In this blog post, we will delve into the importance of cybersecurity in power systems and explore measures to safeguard transmission and distribution infrastructure.

Understanding the Landscape:

Power systems, encompassing transmission and distribution, are the backbone of any nation's infrastructure.  As these systems become more interconnected and reliant on digital technologies, the vulnerability to cyber threats escalates.  Transmission and distribution manufacturers in India are at the forefront of adopting innovative solutions to enhance the efficiency of power systems.  However, with this increased connectivity comes the imperative need to fortify these systems against cyber attacks.

The Role of Cybersecurity in Power Systems:

Protecting Critical Infrastructure:

Cybersecurity plays a pivotal role in protecting critical infrastructure, especially in the power sector.  Transmission and distribution manufacturers in India are recognizing the significance of robust cybersecurity measures to safeguard their equipment and networks.

Securing Outdoor Support Insulators:

Outdoor support insulators are crucial components in power systems, providing structural support and insulation.  Cyber threats targeting these insulators could compromise the integrity of the entire power grid.  Implementing cybersecurity protocols ensures the resilience of these components against potential attacks.

High Voltage Primary Bushing Outdoor Manufacturers in India:

Manufacturers producing high voltage primary bushings outdoors are well-aware of the challenges posed by cyber threats.  Implementing stringent cybersecurity measures is imperative to prevent unauthorized access and manipulation of these critical components.

Addressing Vulnerabilities in Fuse Cutouts:

Fuse cutouts are essential for protecting power distribution systems from overcurrents.  However, these components are susceptible to cyber threats that could disrupt their functionality.  Cybersecurity measures are crucial in identifying and addressing vulnerabilities in fuse cutouts.

Cyber Threats in Power Systems:

Malware and Ransomware Attacks:

Malicious software and ransomware attacks pose a significant threat to power systems.  These attacks can disrupt operations, compromise sensitive data, and demand ransom payments.  Implementing robust cybersecurity measures is essential to mitigate the risk of malware and ransomware infiltrations.

Phishing and Social Engineering:

Phishing attacks and social engineering tactics target human vulnerabilities within organizations.  Employees in transmission and distribution manufacturers in India must be educated on recognizing and avoiding these cyber threats to prevent unauthorized access to critical systems.

Insider Threats:

Insider threats, whether intentional or unintentional, can pose a severe risk to power systems.  Establishing comprehensive access controls, monitoring systems, and conducting regular employee training can help mitigate the potential impact of insider threats.

Safeguarding Strategies:

Network Segmentation:

Implementing network segmentation is crucial to isolate and contain cyber threats.  This strategy ensures that even if one part of the network is compromised, the entire system remains secure.

Regular Security Audits:

Conducting regular security audits is essential for identifying vulnerabilities and weaknesses in power systems.  Transmission and distribution manufacturers in India should prioritize periodic assessments to stay ahead of evolving cyber threats.

Employee Training Programs:

Employees play a crucial role in cybersecurity.  Training programs should focus on raising awareness about potential threats, recognizing phishing attempts, and promoting a security-conscious culture within the organization.

Advanced Authentication Protocols:

Implementing advanced authentication protocols, such as multi-factor authentication, adds an extra layer of security to prevent unauthorized access to critical systems.

Conclusion:

As power systems evolve with technological advancements, the need for robust cybersecurity measures becomes paramount.  Transmission and distribution manufacturers in India must prioritize safeguarding their infrastructure against cyber threats to ensure the continuous and reliable delivery of power.  From outdoor support insulators to high voltage primary bushings outdoors and fuse cutouts, every component plays a critical role in the functioning of power systems and requires protection from potential cyber attacks.

In the face of evolving cyber threats, a proactive approach to cybersecurity is the key to resilience.  By adopting advanced cybersecurity measures and staying abreast of the latest developments in the field, Radiant Enterprises and other stakeholders in the power industry can fortify their transmission and distribution infrastructure, contributing to a secure and sustainable energy future.

No-stress summer learning challenge 🌞: day 43

03.08.2023

It's been quite a long time since the last update, but I haven't abandoned this challenge, I'm learning as planned. I just didn't have time to make an update. I've finished the design of an unstabilised power supply (which is a part of this course). The second photo shows a PIR motion sensor, that will be used for a cat fountain, so that the pump only starts running, when one of my cats walks nearby.
