Measurement & Analysis Instruments
When selecting a power measurement instrument, it's crucial to adopt a comprehensive approach that empowers development teams to meet their objectives throughout the development cycle. Besides addressing specific needs for power accuracy, waveform analysis, or data acquisition, the selected technology should be accompanied by adequate training, hardware, and software. Such support maximizes the value of your investment. Regardless of the electromechanical phenomena to measure, reliable computation capabilities, accuracy, and measurement technologies over the long term are essential. This includes hardware, software, and services that assist engineers and manufacturers in evolving their products from concept through production with enhanced quality and reduced timeframes.
The market presents numerous instruments that might suit various power measurement needs. Depending on particular circumstances, one might require an oscilloscope for waveform analysis, a power analyzer for high accuracy, or a hybrid method that fuses both with the added functionality of data acquisition. Generally, power measurement instruments can be classified into three main categories. Below is a description of the various instruments and their core functionalities.
Among the key players in the field, Yokogawa offers two instruments that enhance capabilities beyond the conventional options: the Power Scope and the ScopeCorder.
The fundamental principle behind power measurement instruments involves sampling the voltage and current waveforms simultaneously, multiplying them post-acquisition, integrating instantaneous power readings over a complete number of fundamental waveform cycles, and dividing by time. However, the analog-to-digital converter's resolution and sampling rate categorize power measurement instruments as either continuous streaming or digital storage types.
Continuous streaming devices, which include traditional power meters and analyzers, utilize high-resolution analog-to-digital conversion, continually computing voltage, current, and power values to achieve real-time measurements and high accuracy. This architecture allows these instruments to perform computations without any downtime or gaps in data collection.
In contrast, digital storage instruments such as oscilloscopes gather data at high sampling rates, storing it in acquisition memory for processing later. However, during this processing phase, "dead time" occurs as the instrument does not read the input waveform, potentially missing significant data points. Oscilloscopes excel at capturing transient events. However, they are typically less accurate for continual measurements, particularly in compliance testing.
Different stages of product development demand varying capabilities and accuracy levels. For instance, isolated tests for individual components may suffice with limited accuracy during early development phases. However, when testing multicomponent systems, the focus shifts towards optimizing the entire system, thus requiring multichannel, multi-parameter measurements.
During design, engineers must address fast switching speeds, dynamic behaviors, and rapidly changing pulse encounters— necessitating high sampling rates and instantaneous analysis. An oscilloscope is often the preferred instrument for these measurements, enabling automated valences of voltage and currents.
As systems evolve toward production, the need for complex measurements increases, necessitating streamlined data collection across multiple channels with accurate temporal resolutions. This is particularly pertinent in sectors like automotive, where engineers must measure both electrical and physical parameters concurrently.
Maintaining compliance with regulations and standards governing efficiency is another critical component of the measurement phase across various industries. A power analyzer guarantees accuracy under specified conditions, while oscilloscopes and data acquisition instruments typically fall short of compliance testing standards due to their lack of guaranteed AC accuracy.
If you are exploring the latest instrument models, consider checking out the offerings from SUIN. Additionally, you can take a look at the Industrial Power Quality Analyzer Manufacturing to find suitable options for your needs. Furthermore, if your work involves signal generation, the Communication Signal Generator may also come in handy.
In conclusion, a variety of powerful measurement instruments exists within the marketplace. Based on individual project needs, a combination of oscilloscopes, power analyzers, and hybrid data acquisition solutions may be necessary to achieve precise and meaningful results.
