Power inverters are fed with DC current and convert it into AC current, or vice versa. Solar power generation systems normally include an inverter that is fed with DC current from solar cells and converts it into usable AC power. Inverters can lose performance over time, so periodic checks are necessary. By comparing input power with output power, the efficiency of the system can be determined. The 435 and 437 II models can measure the efficiency of these inverters by simultaneously measuring the input and output power of a system to determine how much energy has been lost in the conversion process.
Unified Power Measurement (UPM)
In the past, only experts could calculate the amount of electrical energy being wasted due to power quality problems; utility companies could calculate the cost, but the measurement process required was beyond the reach of the average technician. With the new, patented Unified Power Measurement (UPM) function of the 430 Series II models, you have a handheld tool capable of determining how much electrical energy is being wasted and calculating exactly the additional consumption costs. Fluke’s patented Unified Power Measurement (UPM) system provides the most complete view of available electrical power by measuring:
Classic electrical power parameters (Steinmetz 1897) and electrical power in accordance with the IEEE 1459-2000 standard.
Detailed loss analysis.
Unbalance analysis.
These UPM calculations are used to quantify the financial cost of the energy loss caused by power quality problems. The calculations are performed in the Energy Loss Calculator, using installation-specific information, and determine how much money a company loses due to wasted electrical energy.
AutoTrend: check the trend quickly.
The exceptional AutoTrend function provides fast insight into changes over time. Every displayed reading is recorded continuously and automatically, without having to set threshold levels or intervals and without having to start the process manually. You can quickly view trends in voltage, current, frequency, power, harmonics or flicker on all three phases and neutral. You can also analyze trends using the cursors and the zoom function, even while logging continues in the background.
SystemMonitor: easily check the power supply against the EN50160 standard.
At the push of a button, the exclusive SystemMonitor function provides an overview of the quality of the electrical system and its compliance with the limits of the EN50160 standard or with user-defined limits. The overview is shown on a single screen, with color bars that clearly indicate which parameters fall outside the limits.
The IEC 61000-4-30 CLASS A standard removes the guesswork when selecting a power quality instrument. This standard defines the measurement procedures for each power quality parameter in order to obtain reliable, repeatable and comparable results. It also specifies the accuracy, the bandwidth and the minimum set of parameters. What is more, manufacturers now have a reference point for designing to Class A standards, leveling the playing field for technicians when choosing instruments and thereby improving the accuracy and reliability of measurements as well as work efficiency.
The measurement and control of power quality is still under development, and it is a field in which the use of meters is relatively new. Although basic electrical measurements such as voltage and current were defined long ago, a large number of parameters had not been standardized before, forcing manufacturers to develop their own measurement methods. Today there are hundreds of manufacturers worldwide with proprietary measurement procedures. With so many different instruments, engineers must spend time trying to understand the functionality of the instruments and their measurement algorithms instead of learning about the quality of the power supply itself.
IEC 61000-4-30 Class A standardizes the measurement of:
• Power frequency.
• Magnitude of the supply voltage.
• Flicker, harmonics and interharmonics.
• Dips and swells.
• Interruptions.
• Supply voltage unbalance.
• Mains signaling voltage.
• Rapid voltage changes.
The measurement uncertainty is set at 0.1% of the declared input voltage. Low-cost measurement systems with uncertainties above 1% can incorrectly detect a -9% variation when the threshold is set at -10%. With a Class A certified instrument, events can be classified with confidence using internationally accepted uncertainties. This is especially important when verifying compliance with standards or when comparing results between different instruments or parties.
Dips and interruptions must be measured over a full signal cycle and updated every half cycle. This allows instruments to combine the high resolution of half-cycle sampling with the accuracy of a full-cycle RMS calculation.
Aggregation intervals: A power quality instrument compresses the acquired data into specific periods called aggregation intervals. A Class A instrument must provide data at the following aggregation intervals:
10/12 cycles (200 ms) at 50-60 Hz; the interval time varies with the mains frequency.
150/180 cycles (3 s) at 50-60 Hz; the interval time varies with the mains frequency.
Harmonics must be measured at 200 ms intervals in conformance with the new IEC 61000-4-7/2002 standard. The previous standard allowed 320 ms intervals, which could not be synchronized with the 200 ms aggregation intervals of other Class A measurements.
Using 200 ms intervals allows harmonics calculations to be synchronized with other values such as RMS, THD and voltage unbalance.
The algorithm used to calculate harmonics (FFT) is specified exactly so that Class A instruments arrive at similar harmonic magnitudes. The FFT methodology allows for infinite algorithms that can result in a wide range of different harmonic magnitudes. If it is standardized to 5 Hz bins and the harmonics and interharmonics are summed according to the specific standards, measurements made with Class A instruments will be consistent and comparable.
External time synchronization is required to achieve accurate time stamps, allowing exact correlation of data between different instruments. The accuracy is specified with a tolerance of ± 20 ms for 50 Hz instruments and ± 16.7 ms for 60 Hz instruments. Synchronization of the 10-minute interval with the clock. Synchronization of the 2-hour interval with the clock.
