Dieses Praktikerbuch, geschrieben von einem Mitglied verschiedener nationaler und internationaler Standardisierungsgremien, unterstützt Ingenieure bei Design und Realisierung von Niederspannungsnetzen. Mit seinem Aufbau nach dem jeweiligen Typ des elektrischen Systems, einschließlich asynchrone Motoren, dreiphasige Netzwerke und Beleuchtungssysteme, deckt dieses Fachbuch elektrische und elektrotechnische Grundlagen ab, bietet Informationen zur Implementierung der gültigen NEC- und IEC-Normen und einen Überblick über industrielle Anwendungsbereiche. Unzählige Tabellen, Diagramme und Arbeitsbeispiele helfen bei der Planung elektrischer Systeme. Mit den auf der begleitenden Website verfügbaren Programmen lassen sich Berechnungen nachvollziehen und individuell anpassen.
