  • Analyze Power Quality Issues and calculate the cost of wasted energy in real dollars

    As energy saving equipment becomes more and more prevalent in facilities the need to discover where energy is being wasted is becoming more and more important. At the same time these pieces of energy saving equipment like motor drives and electronic lighting have the potential to disrupt the electrical system due to power quality problems. With the Fluke 434 Series II Energy Analyzer you can find out the cost of energy waste due to poor power quality in terms of real dollars lost. You’ll also have the built-in capabilities for characterizing power quality, conducting load studies and capturing hard-to-find voltage events.

    With its energy logging capabilities and the Energy Loss Calculator function, the 434 II measures the cost of energy wasted due to poor power quality issues in real dollars. Add basic power quality measurements to the package and you’ve got yourself one powerful troubleshooting tool.

    • Quickly see how much money you’re losing due to energy waste in terms of real dollars
    • Get at-a-glance power quality health data in real-time so you can make better maintenance decisions
    • Measure all three phases and neutral with the included flexible current probes
    • Highest safety rating in the industry: 600 V CAT IV/1000 V CAT III rated for use at the service entrance
    • Fluke Connect® compatible – view data locally on the instrument, via Fluke Connect mobile app and PowerLog 430-II desktop software
  • The Fluke 434-II is designed for users who need to get to the solution of the power quality problem as quickly as possible so that they can minimize expensive downtime. The measurement process and display of data is optimized to get to the most important information as quickly as possible. Multiple parameters are measured simultaneously and displayed in formats that quickly describe overall power quality health while giving you the detailed information you need to make better maintenance decisions. Data can be quickly accessed as simple digital values, trend graphs that give you fast insight into changes over time, waveforms, phasor diagrams or analyzed and organized into tabular format such as the event data where the magnitude, duration and time stamping enable rapid correlation to the problems you are experiencing in your facility.


    Energy loss Calculator—Calculate money lost to energy waste in terms of real dollars
    It’s a simple fact, poor power quality can have a big impact on the bottom line. The Fluke 435-II enables you to identify issues and measure energy loss giving you specific insight into the amount of loss in dollars associated things like effective power and with poor power quality characteristics such as reactive power, unbalance, distortion, or neutral current. The 435-II even offers users the flexibility to input cable length and cable diameter so you can calculate loss due to conductor sizing (Or use AUTO mode if you don’t know your cable specification) 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
    The Fluke 430-II utilizes 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 will simplify the task.


    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? Nothing is ever 100% efficient, and the 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 is your inverter at converting your DC power to AC (or vice versa).


    AutoTrend – Quickly See the Trend
    With a unique AutoTrend feature you can get fast insight into 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.
