Calculate energy loss in dollars

The Fluke 434 II Energy Analyzer is the ideal tool for energy logging. Utilizing the new Energy Loss Calculator function, the 434 II measures the fiscal cost of energy wasted due to poor power quality. This energy monetization capability allows you to identify the most energy-wasteful areas of your facility so you can determine potential energy saving solutions. Add basic power quality measurements to the package and you're got yourself one powerful troubleshooting tool.


Key Features

  • Energy loss calculator: Classic active and reactive power measurements, unbalance and harmonic power, are quantified to pinpoint true system energy losses in dollars (other local currencies available)
  • Troubleshoot real-time: Analyze the trends using the cursors and zoom tools.
  • Highest safety rating in the industry: 600 V CAT IV/1000 V CAT III rated for use at the service entrance.
  • Measure all three phases and neutral: With included four flexible current probes with enhanced thin flex designed to fit into the tightest places.
  • Automatic Trending: Every measurement is always automatically recorded, without any set-up.
  • System-Monitor: Ten power quality parameters on one screen according to EN50160 power quality standard.
  • Logger function: Configure for any test condition with memory for up to 600 parameters at user defined intervals
  • View graphs and generate reports: With included analysis software.
  • Battery life: Seven hours operating time per charge on Li-ion battery pack.

Applications

  • Energy monetization - calculate the fiscal cost of energy waste due to poor power quality
  • Energy assessment - quantify the before and after installation improvements in energy consumption to justify energy saving devices
  • Frontline troubleshooting - quickly diagnose problems on-screen to get your operation back online
  • Predictive maintenance - detect and prevent power quality issues before they cause downtime
  • Long-term analysis - uncover hard-to-find or intermittent issues
  • Load studies - verify electrical system capacity before adding loads

About the Fluke 430 Series

The new 430 Series II Power Quality and Energy Analyzers offer the best in power quality analysis and introduce, for the first time ever, the ability to monetarily quantify energy losses.

The new Fluke 434, 435 and 437 Series II models help locate, predict, prevent, and troubleshoot power quality problems in three-phase and single-phase power distribution systems. Additionally, the Fluke-patented energy loss algorithm, Unified Power Measurement, measures and quantifies energy losses due to harmonics and unbalance issues, allowing the user to pinpoint the origin of energy waste within a system.

Energy Loss Calculator
The 430 Series Energy Loss Calculator
Unified Power Measurement

Fluke's patented Unified Power Measurement system (UPM) provides the most comprehensive view of power available, measuring:

  • Parameters of Classical Power (Steinmetz 1897) and IEEE 1459-2000 Power
  • Detailed Loss Analysis
  • Unbalance Analysis

These UPM calculations are used to quantify the fiscal cost of energy loss caused by power quality issues. The calculations are computed, along with other facility-specific information, by an Energy Loss Calculator that ultimately determines how much money a facility loses due to wasted energy.



Energy savings

Traditionally energy savings are achieved by monitoring and targeting, or in other words, by finding the major loads in a facility and optimizing their operation. The cost of power quality could only be quantified in terms of downtime caused by lost production and damage to electrical equipment. The Unified Power Measurement (UPM) method now goes beyond this to achieve energy savings by discovering the energy waste caused by power quality issues. Using the Unified Power Measurement, Fluke's Energy Loss Calculator (see screen shot below) will determine how much money a facility is losing due to waste energy.

Unbalance

UPM gives a more comprehensive breakdown of the energy consumed in the plant. In addition to measuring reactive power (caused by poor power factor), UPM also measures the energy waste caused by unbalance; the effect of unevenly loading each phase in three-phase systems. Unbalance can often be corrected by reconnecting loads on different phases to ensure the current drawn on each phase is as equal as possible. Unbalance can also be corrected by installing an unbalance reactance device (or filter), that will minimize the effects. Correcting unbalance should be basic good housekeeping in the facility as unbalance problems can cause motor failure or shorten equipment life expectancy. Unbalance also wastes energy. Using UPM can minimize or eliminate that energy waste, thus saving money.



Harmonics

UPM also provides details of the energy wasted in your facility due to the presence of harmonics. Harmonics may be present in your facility due to the loads you operate or may be caused by loads in adjacent facilities. The presence of harmonics in your facility can lead to:

  • overheating transformers and conductors
  • nuisance tripping of circuit breakers
  • early failures of electrical equipment

Quantifying the cost of wasted energy due to the presence of harmonics simplifies the return-on investment calculation needed to justify purchasing harmonic filters. By installing a harmonic filter the ill effects of harmonics can be reduced and energy waste eliminated, resulting in lower operational costs and more reliable operation.


The 430 Series Data Display
The 430 Series Data Display
Measures everything

Measure true-rms, peak voltage and current, frequency, dips and swells, transients, interruptions, power and power consumption, peak demand, harmonics up to the 50th, inter-harmonics, flicker, mains signaling, inrush and unbalance.



Logger: record the detail you need

User-configurable, long-term recording of MIN, MAX and AVG readings for up to 150 parameters on all 4 phases. Enough memory is available to record 600 parameters for over a year with 10 second resolution, or capture smaller variations with resolution down to 0.25 seconds. The logger function is quickly accessed by the LOGGER button, the simple step-by-step setup makes capturing your important measurements as easy as can be.



System-monitor: summary screen of overall power quality health

The MONITOR mode delivers a dashboard display of rms voltage, harmonics, flicker, interruptions, rapid voltage changes, swells, unbalance, frequency and mains signaling.

The dashboard is updated live, showing compliance of each parameter to EN50160 limits or your own limits. Color-coded bars clearly show which parameters are inside (pass) or outside (fail) limits. During a monitor session, you can easily drill down to more detail of any parameter to view and capture its trend for a report.



Automatic transient display

Every time an event or voltage distortion is detected, the instrument triggers and automatically stores voltage and current waveforms on all three phases and neutral. The analyzer will also trigger when a certain current level is exceeded. Hundreds of dips, swells, interruptions and transients can be captured this way. You can see voltage transients as high as 6 kV and as fast as 5 microseconds.

Extensive data analysis possibilities

The Fluke 430 Series II analyzers provide three ways to analyze measurements. Cursors and zoom tools can be used "live" while taking measurements, or "off line" on stored measurement data. Additionally, the stored measurements can be transferred to a PC with the included software to perform custom analysis and create reports. Measurement data can also be exported to common spreadsheet programs. Store hundreds of measurement datasets and screen captures for use in reports (depending on memory capacity).



Easy to use

Pre-programmed setups and user-friendly screens make power quality testing as simple as you would expect from Fluke. The high-resolution color screen updates every 200 ms and displays waveforms and wiring diagrams color coded to industry standards. Handy on-screen wiring diagrams for all commonly used three-phase and single-phase configurations guide you through connections.



CAT IV 600 V and CAT III 1000 V safety rating

Designed to help protect you and your equipment, the Fluke 430 Series II analyzers and accessories are all certified to meet the stringent standards for use in CAT IV 600 V and CAT III 1000 V environments such as power connections and outlets throughout a low-voltage power distribution system.
