Three Phase Power Analyzers


Fluke Corporation announces the availability of the Fluke® 430 Series II Three Phase Power Analyzers, the first tools to use a patented algorithm to measure energy wasted by power quality issues and quantify its cost. By providing the ROI data needed to justify power quality improvements, the 430 Series II helps facilities reduce electrical power consumption and improve the performance and lifespan of electro-mechanical equipment.

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. 

PowerWave data capture — capture fast RMS values to see every waveform so you can determine how the voltage, current and frequency values are interacting. 

Power inverter efficiency — assess power inverter efficiency.

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. 

Long the most popular three phase power analyzers on the market because of their simultaneous display-and-record capabilities, the updated 430 Series II models have up to 32 GB (8 GB standard) memory, a swappable SD memory card and USB connectivity for longer power and energy logging and faster data download. Screen quality and battery life are both improved and the accompanying software gives users more options to analyze both power quality and power consumption.Both models are fully compliant with IEC 61000-4-30 Class-A. Each one can monitor systems with up to ten power quality parameters on one screen and can record up to 150 parameters on four phases simultaneously, in accordance with the EN50160 standard, and are safety rated 600 V CAT IV/1000 V CAT III. 

Previously, only experts could calculate how much energy was being wasted due to power quality issues; utilities could calculate the cost but the process was beyond the reach of average electricians. With the new, patented Unified Power function of the 430 Series II, electricians, utility technicians, electrical engineers, field service technicians, and energy consultants can determine how much power is being wasted and calculate exactly what the extra consumption costs with a single handheld tool. The 430 Series II Inverter Efficiency function simultaneously measures the input and output power of inverters in solar systems, wind turbines and uninterrupted power supplies, allowing the operator to see how much electricity the inverter itself is consuming and whether it is operating efficiently. The measurements enable operators to adjust settings or make a case for a replacement unit.

The 435 model includes PowerWave, a “fast capture” system that displays waveforms and half cycle RMS voltage and current values in full detail so motor and generator operators can measure the interaction during switching operations. This allows facility and utility service electricians, electrical contractors, and generator suppliers to easily gather measurements with one tool for load profiling, to prevent motor/drive/load mismatches, and for motor and generator commissioning and start-up testing.
