The Fluke 434-II Energy Analyser is designed to help you minimise downtime, quickly troubleshoot power quality issues and easily discover the costs of wasted energy. Downtime is expensive and getting the data you need to solve to critical power quality problems quickly is key. The 434-II Analyser measurement process and data output have been optimised to help you access the most critical information easily.

Multiple parameters are measured simultaneously and displayed in formats that quickly describe overall power quality health. The detailed information helps you make better maintenance decisions—whether you’re trying to reduce energy waste, find the source of power quality issues or see how motor startups are affecting your electrical system. Data can be accessed as simple digital values, trend graphs (for fast insight into changes over time), waveforms, or phasor diagrams. The data can also be analysed and organised into tabular formats. Detailed event data allows you to see the magnitude, duration and time stamping of anomalies enabling you to rapidly correlate the problems you are experiencing in your facility.

Energy Loss Calculator—Calculate money lost to energy waste in terms of real dollars.

430 Series Energy Loss Calculator

It’s a simple fact, poor power quality can have a big impact on the bottom line. The Fluke 434-II Energy Analyser enable you to identify issues and measure energy loss giving you specific insight into the amount of loss in dollars. The Energy Loss Calculator helps you better understand your energy consumption by creating associations between things like effective power and poor power quality characteristics such as reactive power, unbalance, distortion, or neutral current. The energy analyser also offer users the flexibility to input cable length and diameter to calculate loss due to conductor sizing (or use AUTO mode if cable specifications are unknown) and enter up to four unique time-dependent daily rates (kWh) for more accurate calculations. Armed with this critical data, users can easily justify the investment necessary to take countermeasures.

Advanced Power Quality Health—At-a-glance power quality health data in real-time so you have the data you need, when you need it

Advanced Power Quality Health

The Fluke 434-II Energy Analyser utilise an integrated Power Quality Health summary that gives you an at-a-glance view of a complete range of power quality issues in real time. With a simple graphical presentation, complete with tolerance limits, you can quickly discover which power quality problems may be present on your electrical system. If you don’t know where to start or what problems might exist, the advanced Power Quality Health summary simplifies the task and serves as a comprehensive starting point for further troubleshooting.

Power Inverter Efficiency

Power inverters take dc current and transform it into ac current, or vice versa. But, what percentage of that power going into the inverter comes out as usable current? The Fluke 434-II Analysers has an integrated power inverter efficiency mode that allows users to better understand power inverter performance. Nothing is ever 100 % efficient, and a power inverter’s efficiency will vary depending on how much power is being used at the time (with the efficiency generally being greater when more power is being used). Inverters can also lose performance over time and need to be checked. By comparing the input power with the output power, you can determine the system efficiency. With the Power Inverter Efficiency feature you can discover just how good your inverter is at converting your dc power to ac (or vice versa).

AutoTrend—Quickly see the trend

Auto Trend

With a unique AutoTrend feature you can get fast insight into power quality changes over time. Every displayed reading is automatically and continuously recorded without having to set up threshold levels or having to manually start the process so you can quickly view trends in voltage, current, frequency, power, harmonics or flicker on all three phases plus neutral.
