【瞬低の基礎知識​】瞬低(瞬時電圧低下)と停電の違い

【瞬低の基礎知識​】瞬低(瞬時電圧低下)と停電の違い

知っているようで知らない雷の基礎知識！瞬低と停電の違いについてご紹介

瞬低(瞬時電圧低下)と停電の違いについてご説明いたします。 「瞬低」はごく短時間、瞬間的に生じる停電のことです。どれくらい短時間の 停電を指すのかはケースバイケースですが、電力会社では、概して1分未満の 停電を指すケースが多くあります。 「停電」は主に落雷や雪害などにより、送電線のショートが原因で商用電源の 供給が完全に停止し、交流電圧がOVになり、1分間以上続く長い電力の停止状態の ことを言います。 【補償電源】 ■瞬低 ・瞬低保護電源 or 無停電電源 ■停電 ・無停電電源(UPS) ※詳しくはPDF資料をご覧いただくか、お気軽にお問い合わせ下さい。
