Key features

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 visa 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.

Reviews: Fluke 434 Series II Energy Analyzer

Rated 5 out of 5 by from Power Quality and Solar Power helped with Fluke 43 We install PV systems in the Northeast. We recently had issues with performance of a system when full power output was reached. Using our Fluke 434, we were able to collect power quality information such as voltage and current harmonics, and AC waveform distortion, and used this to work with the PV inverter manufacturer to solve the problem. This is a great tool to have at our disposal.

Rated 3 out of 5 by from The Good is Really Good, The Bad Is Really Bad The sad thing about the following is that I have used Fluke meters for decades with great results til now. I rented a 435-II for product performance tests on a 480V Delta system. Meter setup and hookup were simple, data looked good. Then I downloaded the data to Excel and found it was worthless- which may have killed a $200k project, cost $$$ to do, and must be repeated. Every data set was missing crucial values- different ones every time. (See data images) True power showed the totals but no per-phase data. Apparent power totals were usually correct, but only C-A phase data appeared- or none. All 3 phases of reactive power were recorded, but one phase sometimes went negative, which the meter dutifully used to calculate the wrong total. This sometimes happened with amps and power factor. This was not a setup problem. One practical matter- be careful what you download to Excel. I downloaded everything the first time, including Min, Max, Average & Status, and had a spreadsheet with over 2,400 columns, most of which had zero values.

Rated 4 out of 5 by from Knowledge is power, this tool gives users a lot of power. We purchased this unit about 1 year ago anticipating that it would be used mostly for calibration testing and harmonic distortion investigations. But, since then the Fluke 434 has saved the day several times when various vendors (specifically our UPS vendor & our generator vendor) start pointing fingers at each other making accusations that would normally be un-provable without extensive on-site vendor support. With the Fluke 434 we were able to quash claims of generator overshoot, and incorrect phasing from the UPS vendors. And also clearly document power anomalies and transient UPS output distortion due to massive spikes emanating from the local grid. The Fluke 434 has proven to be invaluable not only in the laboratory environment but in the real world of customer support as well.
