Fluke Three-phase Power Quality and Energy Analyser

The Fluke three-phase power quality and energy analyser helps to locate, predict, prevent and troubleshoot power quality problems in three-phase and single-phase power distribution systems. The Fluke-patented energy loss algorithm, unified power measurement, measures and quantifies energy losses due to harmonics and unbalance issues, allowing the user to pinpoint the origin of energy waste within a system.
Supplied with:
All the models are supplied with the TL430 test lead and alligator clip set, WC 100 colour coding clips and regional decals, 4 x i430 thin Flexi current probes, BP290 battery, BC430 power adapter with international power adapter set, USB cable A-B mini, PowerLog on CD (including operator manuals in PDF format, 8GB SD card. C1470 soft case (for 434 II and 435 II) and C437 hard case with rollers for the 437 II.

Features and Benefits

Energy loss calculator: Classic active and reactive power measurements, unbalance and harmonic power, are quantified to pinpoint the fiscal costs of energy losses
Troubleshoot real-time: Analyse the trends using the cursors and zoom tools
Highest safety rating in the industry: 600V CAT IV/1000V CAT III rated for use at the service entrance
Measure all three phases and neutral: With included four flexible current probes with enhanced thin flex design to fit into the tightest places
Automatic trending: Every measurement is always automatically recorded, without any set-up
System-monitor: Ten power quality parameters on one screen according to EN50160 power quality standard
Logger function: Configure for any test condition with memory for up to 600 parameters at user-defined intervals
View graphs and generate reports: With included analysis software
Battery life: Seven hours operating time per charge on Li-ion battery pack
Energy monetization – calculate the fiscal cost of energy waste due to poor power quality
Energy assessment – quantify the before and after installation improvements in energy consumption to justify energy saving devices
Frontline troubleshooting – quickly diagnose problems on-screen to get your operation back online
Predictive maintenance – detect and prevent power quality issues before they cause downtime
Long-term analysis – uncover hard-to-find or intermittent issues
Load studies – verify electrical system capacity before adding loads
