The Fluke 434 three-phase power quality meter help you locate, predict, prevent and troubleshoot problems in power distribution systems. These easy-to-use power quality tools are a ﾓmust haveﾔ for any person who maintains or troubleshoots three phase power. The new IEC Class A standards for flicker and power quality are built right in to take the guess work out of power monitoring.
Applications
Frontline troubleshooting ﾖ quickly diagnose problems on-screen to get your operation back online
Predictive maintenance ﾖ detect and prevent power quality issues before they cause downtime
Quality of service compliance ﾖ validate incoming power quality at the service entrance
Long-term analysis ﾖ uncover hard-to-find or intermittent issues
Load studies ﾖ verify electrical system capacity before adding loads
Energy assessments ﾖ quantify energy consumption before and after improvements to justify energy saving devices
