6003A Customer EOL Letter.pdf (91.11 KB)Effective April 2, 2021, Fluke Calibration will cease production and sale of the 6003A Three Phase Electrical Power Calibrator and all its unique and specific accessories and options. Fluke introduced this model in 2014 as a competitive calibrator capable of supplying accurate 3 phases of current and voltage. The Fluke 6130B is the closest replacement for the 6003A. While there is no direct replacement for the 6003A, the 6130B offers significant benefits in...

Grid connected photovoltaic systems are growing in importance as sustainable energy sources.The DC power of the solar panels is converted into an AC power by inverters. These are transformerless and, besides generating AC current, also inject a small DC Current. Excessive DC current injection into an AC network can cause problems like transformer saturation, however, which will cause additional losses and reduce transformer lifetime. For measuring these DC components, we need a Power Quality Analyzer...

Large three-phase motors and the equipment they drive should consume power equally from each of the three mains phases. However, that often doesn’t happen. Unbalance and harmonics can cause instability, with motor vibration that reduces both efficiency and lifetime. Unbalance can also cause malfunctions in single-phase loads. All this can reduce your power quality, leading to punitive penalty charges from your utility.In this blog, we will describe balanced three-phase power systems – where each...

Most of us work in tech support departments and one of the most frequently asked questions we receive is: how to set up a energy logger or power analyzer.We’re always happy to help so we’ve created a video that shows how you can easily setup an Energy Logger from the Fluke 173x series.Fluke 1736 Three-Phase Power LoggerThe power logger used in this video was the Fluke 1736 Three-Phase Power Logger.Fluke 1736 Three-Phase Power LoggerKey measurements: Automatically log voltage, current, power,...

Harmonics can cause high neutral currents in three-phase systems — even ones that are balanced. They heat up cables, which can cause fires. Many installers now check their work using a multimeter, but multimeters can’t measure harmonics.Equipment installation needs a power quality analyzerResistive (linear) loads like heating elements and incandescent lights used to dominate electrical supply networks. The last 10 years has, however, seen many more non-linear loads. Examples are LED lights, variable-speed...

What is IEC 61000-4-30 standard?The IEC 61000-4-30 standard ensures that the measurement results from Power Quality analyzers and loggers of different makes and models match up; so measurement results are comparable without any doubts. This is extremely important, especially when there is a dispute about supply voltage quality between different parties going on. To comply with this standard, the instruments should measure and evaluate in exactly the same way. The standard covers PQ phenomena like...

There are five vital measurements that could be causing problems in your electrical distribution system that you may be missing even with a True-rms digital multimeter. While the digital multimeter is a valuable and indispensable tool for the electrical professional, it does have limitations. A multimeter may be able to alert you to one of these five issues, but be prepared to use a power quality analyzer to dig in further and uncover these hidden potential problems.Those measurements are:1. Harmonic...

Symptoms of power quality issues include vibration, excessive buzzing or humming and overheating. Technicians should occasionally check the power of transformers that supply nonlinear loads, such as variable frequency drives (VFDs) or switching power supplies. Doing so ensures operation within acceptable limits. Transformers are deeply critical to the reliability of the grounding system. During your transformer inspection, use temperature as a guide to check for excessive radiant heat and stay alert...

Power and distribution panels and their nearby wiring are a frequent starting point for technicians when electrical disruptions require troubleshooting. Voltage and current are two of the most common electrical measurements taken at panels and the surrounding wiring. To isolate specific problems, a technician may also want to test for continuity or measure peak voltage, peak current, minimum/maximum voltage (or current) over time, temperature, harmonics, power factor, transient voltage, temperature...

Saving energy and minimizing energy waste is one of the most important aspects of energy use. No matter what industry you work in, looking for energy savings means looking at your power consumption rates and developing a power quality management energy saving plan.Benchmarking electrical energy consumptionThe first step in developing a power quality management program is benchmarking your current electrical energy consumption across the facility. Through that initial survey, you can look for quick...

To the untrained eye, problems in electrical distribution systems or the equipment connected to the circuit may not be recognizable as power quality problems. When no immediate problem is apparent, it may be written off as just an old breaker that needs replacing or a one-time nuisance reset. You might look at types of loads on the system and monitor for harmonics, unbalance, or disturbance patterns.Harmonic distortion issues and voltage and current anomalies represent the areas where common problems...

Power quality is an estimate of how stable the electrical system is, often this is described as “power quality health.” This is measured on three-phase electrical systems using instrumentation that considers several variables. Troubleshooting power quality issues will help your facility save money by optimizing energy use and protect equipment from future damage. The first step to evaluating power quality is to capture data from equipment, infrastructure, and the service panel. The primary effects...
