    Fluke 434-II Three-Phase Energy Analyzer

    Built to help users minimize downtime, quickly troubleshoot power quality issues, and easily discover the costs of wasted energy. Downtime is costly therefore, acquiring data you need to solve to critical power quality issues quickly is key. This unit’s measurement process and data output are optimized to aid you to access 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.

    Fluke 434-II Three-Phase Energy Analyzer Features

    • Battery life: Up to 8 hours operating time per charge on Li-ion battery pack

    Unified power measurement

    The 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, the 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.
