Yokogawa’s European Calibration Laboratory in the Netherlands has achieved ISO 17025:2017 accreditation for power measurements at up to 100kHz – ISO/IEC 17025:2017 is the ‘General requirements for the competence of testing and calibration laboratories’.

It enables both Yokogawa’s laboratory and its customers to demonstrate that they operate competently and generate valid measurement results. Test reports and certificates can be accepted from one country to another without the need for further testing.

“Yokogawa’s laboratory is one of the few non-government organisations in the world to offer accredited power calibration at frequencies up to 100kHz,” according to the company. “As such, it forms a key part of Yokogawa’s strategy to grow its position in the European digital power analyser market.”

Power measurements at frequencies higher than the traditional 50Hz are seldom sufficient as switching loads and sources such as ac-dc converters and inverters introduce harmonics of the operating frequency. at higher frequencies.

As a result, power calibration at 50Hz is no longer sufficient.

Yokogawa’s lab i snot only accredited to 100kHz, but can work with power factors down to 0.0001, and the high currents found in power transformer applications.

Obtaining this new accreditation for the laboratory is proof of Yokogawa’s continuing commitment to giving engineers confidence that the measurements they make are correct.

“The new accreditation confirms the European Standards Laboratory as the world’s leading power calibration facility and ensures we continue to offer the best possible service to test engineers across many industries,” claimed lab manager Erik Kroon (pictured).
