The Fluke 435 Series II Power Quality Analysers offers power quality analysis as well as the ability to monetarily quantify energy losses. It can help 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.
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.
Mains signalling: measure interference from ripple control signals at specific frequencies.
Troubleshoot real-time: Analyse the trends using the cursors and zoom tools.
Safety: 600 V CAT IV/1000 V CAT III rated for use at the service entrance.
Measure all three phases and neutral: 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.
