Method for Detecting an Inrush Event, Computer Program and Separation Device

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention describes a method and system for detecting inrush events (sudden large currents) in transformers connected to an AC electrical power grid. The system analyzes current measurements from the transformer using specific algorithms, determines whether an inrush event is occurring based on these analyses, and outputs a control signal if such an event is detected.

Use CasesContent extracted from patent full text and abstract with AI.

• Detection of transformer inrush currents in power distribution systems

Patent Abstract

Verfahren zum Erkennen eines Inrushereignisses an wenigstens einem an ein elektrisches Wechselspannungsnetz (1) mit einer Netzfrequenz angeschlossenen Transformator (8, 10), umfassend folgende Schritte:- Analysieren eines zeitlichen Verlaufs von Stromwerten wenigstens einer in Abhängigkeit eines Leitungsstroms auf einer mit dem wenigstens einen Transformator (8, 10) verbundenen Leitung (6AB) ermittelten Strominformation mittels wenigstens eines Analysealgorithmus (35, 36, 37);- Bestimmen eines Erkennungswerts (62) für das Vorliegen des Inrushereignisses für eine jeweilige Strominformation in Abhängigkeit eines jeweiligen Ergebnisses (45, 48, 55) der Analyse des wenigstens einen Analysealgorithmus (35, 36, 37);- Auswerten eines einen jeweiligen Erkennungswert (62) verwendenden Erkennungskriteriums; und- Ausgeben eines das Inrushereignis anzeigenden Steuersignals (19), wenn das Erkennungskriterium erfüllt ist.
