The new IEC 61000-4-30 CLASS A standard takes the guesswork out of selecting a power quality instrument. The standard IEC 61000-4-30 CLASS A defines the measurement methods for each power qual- ity parameter to obtain reliable, repeatable and comparable results. It also defines the accuracy, bandwidth, and minimum set of parameters. Going forward, manufacturers can begin designing to Class A standards, giving technicians a level playing field to choose from and increasing their measure- ment accuracy, reliability, and efficiency on the job. IEC 6100-4-30 Class A standardizes measure- ments of: • Power frequency • Supply voltage magnitude • Flicker, harmonics, and interharmonics (by reference) • Dips/sags and swells • Interruptions • Supply voltage unbalance • Mains signalling • Rapid voltage changes It does not standardize measurements of high frequency transients or current-related phenomena. Power quality measurement is still a relatively new and quickly evolving field. Whereas basic electrical measurements like RMS voltage and current were defined long ago, many power quality parameters have not been previously defined, forcing manufacturers to develop their own algorithms. Now there are hundreds of manufacturers around the world with unique measurement methodologies. With so much variability between instruments, technicians often must spend time trying to understand the instrument’s capabilities and measurement algorithms instead of understanding the quality of the power itself.

In this article we’ll talk about the various recording techniques available in power loggers and recorders—understanding the tools and techniques you have available will be key to your strategy. What should you be looking for? And when does recording make sense? To really know your power, ideally, you’d want to look at every line cycle to see even the smallest changes. However, since our power swings through more than four million cycles per day, it’s impracti- cal to look at tiny changes—and often unnecessary. Few loads even notice occasional voltage dips of one or two cycles. How long you record depends somewhat on the rhythm of your building. If you are working on a typical commercial or light indus- trial building, then a week is long enough for a building to go through its normal cycle. If you are work- ing in a plant that runs special equipment only periodically (say a furnace that runs only monthly), you’ll need to be sensitive to the timing of these loads. Different recording techniques have been developed to look at small changes over relatively long time periods. Many instruments combine several techniques to improve their coverage. We’ll describe the common techniques and some of their pros and cons. By understanding the different techniques. you’ll be better able to choose an appropriate tool for the job at hand. Setting up a Fluke 1735 Power Logger at the service entrance for a 30-day load study. Recording techniques Application Note Recording current and power with the Fluke 1735 The compact, rugged Fluke 1735 Power Logger is an excellent tool for performing energy studies. • It includes flexible current probes for connecting around multiple conductors or bus bars. • It has a PC interface and software for downloading measurements to a Windows- based PC and creating pro- fessional reports for your electrical plans. Energy studies with the Fluke 1735 Power Logger The rising cost of energy means that optimal use of energy has become even more critical. The first step in managing energy is understanding ‘how much and when’ energy is being used. To discover that, you need a power logger. The logger captures voltage, current, power, power factor and energy, displays the measurements, and in logging mode stores them over time. Then, using software, you can graph the measurements and highlight times when extreme or unexpected energy consumption is happening. For example, if energy is being consumed at night or at weekends, perhaps the HVAC system needs to be re-programmed? Once you have this kind of power and energy profile, you can highlight potential areas for energy savings. From the Fluke Digital Library @ www.fluke.com/library • It measures voltage on three phases and current on three phases and neutral. • It records multiple parameters that can help determine system load, including voltage, current, frequency, real power (kW), apparent power (kVA), reactive power (kVAR), power factor, and energy (kWh). Conduct the initial energy study at the main utility power supply/service entrance. Once you’ve measured overall power, then conduct more focused studies throughout the facility to profile individual loads and estimate their effect on your electricity bill. Performing a load study with the Fluke 1735 takes just five steps: 1. Hook up to the feeders or service. 2. Set power system parameters. 3. Set the recording time. 4. Start recording. 5. Download and review the measurements.
