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.
