P90Wert
P90Wert is a statistical descriptor that denotes the 90th percentile value within a given data set. The term is commonly used in German‑language technical literature and engineering documentation where the German word “Wert” (value) has been appended to the percentile indicator. In practice, the P90Wert represents the point below which 90 % of all observations lie, leaving the remaining 10 % above that threshold. This metric is especially useful for evaluating processes where high‑tail behavior matters, such as reliability assessments, load forecasting, and risk analysis.
To calculate the P90Wert, the data are first sorted in ascending order. If the data set contains
P90Wert figures prominently in fields such as power system protection, where it may define the short‑circuit
