変圧器容量は、大は小を兼ねることになりません |
|
★ |
変電所のトランス容量が大きいと2重の経費過多というRISKを負います。通常、最大負荷率は80%以上が適正です。 |
★ |
負荷率が100%を越えていても、トランスの温度管理上、夏場のピーク時に90度を超過しなければ問題ありません。 |
★ |
トランス容量が大きいと、電気保安管理費過大による損失A、変電所の銅損・鉄損によるエネルギー損失Bがあります。それぞれの金額は月額の一例です。 |
★ |
複数のトランスが入っている事業所は、低負荷トランスの停止、入替等の対応策が必要です。 |
★ |
設備の見直しを省エネルギー・エコ対応の観点からもお奨めいたします。表の最大電力の所から自社の状況判断をしてみて下さい。 |
|
凡そ8割の事業所で何らかの対処が必要かと思います。 |
