Electricity Meters
Landis+Gyr E850
Präzise Werte für die Verrechnung, umfassende Daten für den Netzbetrieb: Die ZxQ-Reihe von Landis+Gyr wurde von Grund auf für Grid-Anwendungen entwickelt. Eine äusserst niedrige Ansprechzeit, höchste Datenauflösung und die zehntausendfach nachgewiesene Betriebssicherheit prädestinieren den ZxQ für alle Anwendungen im Hochspannungsnetz. Mehr erfahren
