New calibration service keeps AC energy measurement devices accurate

by Erik Kroon January 5, 2022

Many manufacturers need accurate measurement of electrical energy – to meet efficiency goals, for proving product specifications or meeting regulatory requirements such as energy labelling of consumer products.

But can they be sure their energy measuring devices are actually giving a true reading?

What is needed is a service that can calibrate these devices to give the makers of products, equipment, or appliances confidence in their readings.

Such a service has just been launched by Yokogawa – it offers calibration of AC energy measuring devices at up to 40 MWh at a maximum time of 1000 hours.

As well as products, the service will also prove vital for applications such as usage-based billing of electrical energy between supplier and user – not only for houses and offices but also for other applications, for example charging of electric vehicles.

Other uses include renewable energy projects such as photovoltaic and wind installations and end tests and type rating where energy is involved.

The new service follows Yokogawa’s accreditation (K164) to ISO17025 and means that the company’s European Standards Laboratory now offers comprehensive energy and power calibration, which can be customized to meet the needs of specific applications.

The Yokogawa lab is also one of the few places where you can get instruments calibrated in the frequency range 40 Hz to 1 kHz.

This will be particularly attractive to engineers working on applications in Automotive, Aviation and Marine, as it makes it easier to source ISO17025 accredited energy measurements for 400 Hz systems.

Extending its calibration services to include AC energy means that Yokogawa can support customers that need to maintain the accuracy and trusted repeatability of their testing instruments. The result is they can more easily meet regulatory needs for their application and help contribute to saving energy to build a greener future.
