P_TABLEVALUE / IfcElectricCurrentMeasure / IfcElectricCurrentMeasure

| Breaker Unit IPICurve | A curve that establishes the let through peak current of a breaker unit when a particular prospective current is applied. Note that the breaker unit IPI curve is defined within a Cartesian coordinate system and this fact must be asserted within the property set: (1) Defining value: A list of minimum 2 and maximum 16 numbers providing the currents in [A] for points in the I/Î log/log coordinate space. The curve is drawn as a straight line between two consecutive points. (2) Defined value: A list of minimum 2 and maximum 16 numbers providing the let-through peak currents, Î, in [A] for points in the I/Î log/log coordinate space. The curve is drawn as a straight line between two consecutive points.
| 遮断機曲線 | 適用された電流と通過する遮断機のエネルギーを示した曲線 （1）定義値：ProspectiveCurrent（固有電流）： 電流/I2tで示される最小2から最大8のリストで電流[A]を定義します。 カーブが連続する2つの点を結ぶ直線として描かれています。 （2）定義値：LetThroughEnergy： 電流/I2tで示される最小2から最大8のリストで通過エネルギー電流[[A2s]を定義します。 カーブが連続する2つの点を結ぶ直線として描かれています。
