400Hz measurement and shipboard power measurement
If you’re dealing with aviation systems measuring key parameters at 400Hz is a must . The Fluke 437-II provides that capability (and measures at 50 and 60Hz too). 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 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 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.

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.

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.

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.
