The Effect of Internal Phase Shift on Power Measurement Uncertainty

door

Here’s a new article that we thought all Vermogenselektronica 2015 registrants and attendees might find interesting reading:

“The measurement of electrical power depends on three factors: voltage, current and time. All three factors contribute to the total uncertainty of the measurement, but what is often overlooked is the contribution of the measuring instrument’s internal phase-shift uncertainty to the total power measurement uncertainty. This article examines these uncertainties in detail, and shows how their effects can be minimised by careful powermeter design.”

About Yokogawa Test & Measurement

Yokogawa has been developing measurement solutions for 100 years, consistently finding new ways to give R&D teams the tools they need to gain the best insights from their measurement strategies. The company has pioneered accurate power measurement throughout its history, and is the market leader in digital power analysers.

Yokogawa instruments are renowned for maintaining high levels of precision and for continuing to deliver value for far longer than the typical shelf-life of such equipment. Yokogawa believes that precise and effective measurement lies at the heart of successful innovation – and has focused its own R&D on providing the tools that researchers and engineers need to address challenges great and small.

Yokogawa takes pride in its reputation for quality, both in the products it delivers – often adding new features in response to specific client requests – and the level of service and advice provided to clients, helping to devise measurement strategies for even the most challenging environments.

The guaranteed accuracy and precision of Yokogawa’s instruments results from the fact that Yokogawa has its own European standards laboratory at its European headquarters in The Netherlands. This facility is the only industrial (i.e. non-government or national) organisation in the world to offer accredited power calibration, at frequencies up to 100 kHz. ISO 17025 accreditation demonstrates the international competence of the laboratory.
