10 + 1 Reasons to Choose a Yokogawa Power Analyzer
■Power analyzers and power meters measure electrical power in devices that generate, transform, or consume electricity. Since they offer the accuracy, frequency ranges, and functions necessary to meet industry test and measurement standards, they have been used for decades in electrical product testing applications. More than simply watt meters, these instruments make true power measurements using matched voltage and current input circuits. They are able to make power measurements in single-phase, three-phase/three-wire, and three-phase/four-wire circuits.
■In order to provide the best solution for a broad range of applications while staying within budget, power analyzer and power meter portfolios feature a variety of measurement accuracies, frequency bandwidths, and prices. High-end power analyzers offer measurement accuracy as good as ±0.01% of reading. Depending on the model, the specified power measurement frequency can range from DC to 1 MHz.
■Some power analyzers offer harmonic measurement functions. The best instruments are able to characterize harmonic data and total harmonic distortion (THD) simultaneously with normal power measurements. This enables the highest efficiency in the testing process and, in some instruments, allows compliance testing to IEC 61000-3-2 or IEC 62301. However, please beware that the ability to perform a Fast Fourier Transform (FFT) does not necessarily mean that an instrument complies with IEC harmonic measurement requirements.
■This application note discusses the top 10 reasons, plus one, to select a Yokogawa power analyzer.
