Key features

The Fluke 435-II products are 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.

PowerWave Data Capture— Quickly identify how motor and generator startups are impacting equipment performance
With PowerWave data capture you can capture three-phase high resolution voltage and current waveforms for up to five minutes along with detailed RMS voltage and current values. By analyzing the interaction of these values over time you can correlate the effects of voltage, current and frequency during the critical startup of motors and generators. PowerWave even goes beyond the standard power quality measurements allowing you to record half cycle rms values on 8 channels, frequency and instantaneous power (Vrms1/2, Arms1/2, W, Hz and scope waveforms for voltage, amps and watts).

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
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.

Rated 2 out of 5 by from Powerlog software is very poor I am using Fluke 435 Series II for last 4 years. I find the Powerlog software very primitive and rigid. It is very difficult to do the analysis. I tried to contact at many levels but did not get any positive response. At lease someone will take cognizance of my review and will look into the matter.

Rated 4 out of 5 by from Good flexibility - easy to use Between the well designed jaws of the voltage clips and the flexible amperage leads, this meter shows obvious tailoring to field use. Information obtained can be set up for fairly simple information viewing and retrieval or the complex information wanted by serious engineers. One things to watch is the firmware updates. Fluke support can work through about anything so it's easier to check with them prior to updating.

Rated 5 out of 5 by from Outstanding Analyzer Purchased for analysis of power panels in Communication Facilities. Had problems with the facilities overloading Power Phases and had to have a way to prove to the Facility Engineer that the loads need to switched around to balance the different phases. With the memory capability, was able to real time screen shots to use in survey reports.

Rated 5 out of 5 by from Excellent Product! We install machines in factories all over the world. A lot of them have been in the same location for many years and the electrical systems have not been updated in many years. (Noisy overhead cranes, welders, etc.) Whenever there is a question, we send the Fluke out and monitor the incoming power to ensure that all is well. In the amount of service time that this has saved, it has paid for itself many times over!

Rated 5 out of 5 by from Great Product I've used many different types and manufacturers of Power Quality Analyzers. The 435 is by far my favorite. The ease of use, setup and reporting makes it my first "go to" piece of equipment. We also use it for a wide variety of applications and it's never failed us. Highly suggest the 435 or any model in this line.

Rated 5 out of 5 by from Powerful Tool I'm an industrial and commercial electrician. I originally purchased my 435-II to do a power qualify study on a chiller at a customer's facility under the direction of an electrical engineer. The unit captured the specified measurements, and is intuitive and easy to use and set up. Since then, I've used the 435-II in a number of troubleshooting and documenting senarios, especially 3-phase motor commissioning and troubleshooting. I've found the ability to document a system's performance to be invaluable in validating an install or troubleshoot. The ability to capture screenshots via Fluke Connect is also useful for documenting a system's condition. The only problem is: the 435-II spoiled me. Now, I always want to see voltage and current on all power legs simultaneously, on every troubleshoot.
