The new Fluke 430 Series II 400 Hz Three-Phase Power Quality and Energy Analyzers offer the best in power quality analysis and introduce, for the first time ever, the ability to monetarily quantify energy losses

The Fluke 437-II helps locate, predict, prevent, and troubleshoot power quality problems in three-phase and single-phase power distribution systems. Additionally, 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

Energy loss calculator: Classic active and reactive power measurements, unbalance and harmonic power, are quantified to pinpoint true system energy losses in dollars.

Power inverter efficiency: Simultaneously measure AC output power and DC input power for power electronics systems using optional DC clamps.

PowerWave data capture: Capture fast RMS data, show half-cycle and waveforms to characterize electrical system dynamics (generator start-ups, UPS switching etc.).

Waveform capture: Capture 100/120 cycles (50/60Hz) of each event that is detected in all modes, without set-up.

Automatic Transient Mode: Capture 200 kHz waveform data on all phases simultaneously up to 6 kV

Fully Class-A compliant: Conduct tests according to the stringent international IEC 61000-4-30 Class-A standard.

Mains signaling: Measure interference from ripple control signals at specific frequencies.

400 Hz measurement: Captures power quality measurements for avionic and military power systems.

Troubleshoot real-time: Analyze the trends using the cursors and zoom tools.

Highest safety rating in the industry: 600 V CAT IV/1000 V 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 designed 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.
