The Fluke 435-II Power Quality and Energy Analyzer are designed to help you minimize 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. 435-II Analyzer’s measurement process and data output have been optimized 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 analyzed and organized 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.
It’s a simple fact, poor power quality can have a big impact on the bottom line. The Fluke 435-II Power Quality and Energy Analyzer 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. These power quality and energy analyzers 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.
The Fluke 435-II Power Quality and Energy Analyzer utilize 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 435-II Analyzers have 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).

The integrated shipboard power measurement system analyzes according to MIL-STD 1399 to automatically give a full evaluation of voltage, current and power according to the standard. This evaluation makes measurement and analysis as easy as can be. The measurement process, and the way the 437-II displays data has been optimized to provide to the most important information as quickly as possible. Multiple parameters are measured simultaneously and are 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, viewed as trend graphs that give you fast insight into changes over time, or viewed as waveforms and phasor diagrams or analyzed. Data can also be organized into tabular format for viewing events where the magnitude, duration and time stamp enable rapid correlation to the problems you are experiencing.
