Fluke 433 Three-Phase Power Quality Analyzer

Description

The Fluke 434 and 433 three-phase power quality analyzers help you locate, predict, prevent and troubleshoot problems in power distribution systems. These easy-to-use handheld tools have many innovative features to give you the details to pinpoint problems faster and safer.

 

Features

  • Complete three-phase troubleshooting tool:
    • Measures virtually every power system parameter: voltage, current, frequency, power, power consumption (energy), unbalance and flicker, harmonics and inter-harmonics.
    • Captures events like dips and swells, transients, interruptions and rapid voltage changes.
  • AutoTrend:
    • No time wasted setting up additional trend graphs while every measurement is automatically recorded.
    • Analyzes trends using cursors and zoom function, while recording continues in the background.
  • System-Monitor:
    • Gives immediate insight into power system’s quality.
    • Checks conformity to limits specified in EN50160 or to own custom limits.
  • Four channels:
    • Simultaneously measures voltage and current on all three phases and neutral.
  • Automatic transient display:
    • Captures up to 40 dips, swells, interruptions or transients automatically.
  • Meets the stringent 600 V CAT IV, 1000 V CAT III safety standard required for measurements at the service entrance.
  • Rugged, handheld instrument operates for more than 7 hours on included rechargeable NiMH battery pack. Menu-driven interface simplifies operation.
  • Extensive data analysis possibilities. Cursors and zoom can be used ‘live’ while taking the measurements, or ‘offline’ on stored measurement data. The stored measurements can also be transferred to a PC with FlukeView software (included with Fluke 434).
  • Complete package includes everything to get started: 4 current clamps, 5 voltages test leads and clips, line adapter/battery charger and hard case.
  • Complies with IEC 61000-4-30 measurement standards.
