You can hear the voice recording for the diary.
今日は祝日でお休みのため、いつもの電気の勉強会を開催してもらった。
Today was a national holiday, and I took the opportunity to have an extra study session with my former senior colleague.
その中で、以前話があった、発電した電気を電力会社が運営、管理する変電所の３次回路に接続する方法を、さらに詳しく教えてもらった。
During our session, I asked him to explain how to connect the generated electricity to the tertiary side of the transformers, which are operated by the electricity power company.
わたしの完全な知識不足であるが、変圧器の３次巻線は定格電圧が69kVであり、通常の66kV系統よりも高く、特注の機器が必要であること。結線方法も異なるため、送電線として電力を供給する場合、接地変圧器といった追加機器が必要であると教えてもらった。
While this topic was a gap in my knowledge, I quickly learned that connecting to the tertiary side of transformers, although done at some substations, is challenging. The nominal voltage for the tertiary side is slightly higher than the standard 66kV networks, making customer-ordered equipment mandatory. Additionally, due to differences in electrical wiring, external facilities like ground transformers are needed to supply electricity to the national grid.
うーん、ただでさえ、電気は奥が深いのに、それをさらに感じた勉強会であった。ホントにわたしにできるか不安でしょうがない。
My understanding of electrical systems is already quite deep, but I realized that the complexity runs even deeper than I had initially thought. It became apparent that I may not be able to handle this on my own.
To be continued.
