Yokogawa Receives Accreditation for Power Calibration up to 100kHz

Yokogawa offers a product portfolio for acute power measurement, data acquisition, provides digital power analyzers and meters, optical test equipment, oscilloscopes, and an extensive range of calibration and other services.

Recently, Yokogawa’s European Calibration Laboratory (based in Amersfoort, Netherlands) received accreditation for the latest ISO 17025:2017 standard for power measurements at up to 100 kHz. Yokogawa is the first industrial organization in the world to provide accredited power calibration at this frequency range.

What This Means for Yokogawa and its Customers

Being able to accommodate power calibration up to 100kHz enables Yokogawa to meet the calibration requirements of modern electronics with faster switching speeds. It also allows for greater measurement certainty regarding devices operating at a wider range of frequencies. 

Calibration is used by engineers to test system or device performance against that of a standard with known accuracy. The method is non-invasive and can provide information on device and system operational efficiency.

“Several years ago we started the lab with an ambition to become the best commercial power calibration lab in Europe. Today we are proud to provide worldwide leading power calibration in frequencies up to 100 kHz, of unmatched uncertainty,” said Yokogawa Calibration Laboratory Manager, Erik Kroon.

The standard ISO/IEC 17025:2017 (RvA K164), General requirements for the competence of testing and calibration laboratories demonstrates Yokogawa’s  European Calibration Laboratory’s ability to provide trusted and accurate measurement results. This means that engineers are provided with a form of quality assurance. 

 

Yokogawa’s Power Technologies

Power analyzers are used to measure the power consumption, loss or overall efficiency of electronic devices. This instrument can be applied to a variety of applications from home and office appliances, to renewable energy, inverters, and electric motors. This requires specific calibration to meet application requirements.

Today’s power conversion technology incorporates high-speed switching and harmonic content is introduced at much higher frequencies. In any of the applications mentioned here, voltage and current signals can be distorted by the inverter. 

This necessitates analysis of higher frequency components. Yokogawa’s 100 kHz ISO/IEC17025 accredited (RvA K164) power calibration system was developed for the calibration of electrical power at DC and AC from 10 Hz to 100 kHz. Calibration with a wide frequency range can provide traceability on power measurements with distorted waveforms and prove the performance of power analyzers.

“By achieving accreditation to ISO/IEC 17025:2017, we have shown we are keen to take on new concepts and maintain our facilities in the front rank of calibration service providers,” said Terry Marrinan, Yokogawa’s Vice President, Test & Measurement, for Europe & Africa in a news release.
