Why use a CAT III rated meter in solar PV installations?

Overvoltage categories in a photovoltaic installation connected to the utility energy grid

ソーラー設備 (太陽光発電設備または PV 設備とも呼ばれる) は、電力事業スケールの太陽光発電の経済性に説得力があること、そして電力網を脱炭素化しようとする取り組みに後押しされ、急増を続けています。ソーラー配電システムと負荷が大きく複雑になるにつれ、過渡過電圧発生の可能性も増し、安全性がかつてなく重要な意味を持つようになっています。

ソーラー専用: Fluke 393 FC CAT III 1,500 V TRMS クランプ・メーター

ソーラー設備の測定を行う際に、これらの過渡事象は目に見えないため、ほとんど不可避の危険です。つまり、測定者がどれだけ保護されるかは、ツールにすでに組み込まれている安全マージンに左右されることになります。そこで測定カテゴリー定格が役に立ちます。測定カテゴリーは、測定デバイスが安全に測定できる電気設備の種類をユーザーに知らせることを目的に設計されています。
