Condition: Used
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.
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 optimiz ing their operation. The cost of power quality
could only be quantified in terms of downtime caused by lost production and damage to electri cal 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
PM 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-oninvestment 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.
