Implications of the Updated EN 50522 Standard on Earthing Testing #91
In Energy Talks Episode 82, we spoke in detail with experts Christian Raunig and Theodor Connor, about the revision of the EN 50522 standard for earthing (grounding) testing. The focus was on how this European standard was developed, the work of the standards committee, and the recent changes to the content of the standard.
In this episode, we dive even deeper into the subject matter and discuss the impact on measurements using the revised EN 50522 standard with Josef Schmidbauer, an expert in earthing (grounding) testing and product manager of OMICRON’s COMPANO 100.
Josef highlights the implications of recent updates made to the EN 50522 standard, including the recommended earthing (grounding) measurement procedures to enhance safety and reliability. Josef also discusses the importance of touch voltage measurements, interference suppression methods, and the advantages of the frequency-selective method for earthing (grounding) measurements. Lastly, he explains how modern testing equipment allows for safer, more efficient and highly reliable earthing and grounding testing.

"The updated EN 50522 standard has increased distance requirements for measurements and frequency selective methods are now preferred for their accuracy.”
