Did you know that the UK Engineering Recommendation ER G5/5 (2020) has updated harmonic limits, extending measurement requirements up to the 100th order — replacing the older limits that stopped at the 50th order?
If your facility is still relying on PQ loggers limited to the 50th order, you may be missing critical harmonic data that directly affects power quality, compliance, and equipment performance.
At PQE Power System, we stay ahead of regulatory changes to ensure our clients’ monitoring systems are accurate, compliant, and future-ready. Upgrading to advanced solutions that measure up to the 100th order ensures you capture the full picture of your electrical system’s harmonics, protecting both equipment and operations from unseen risks.
Don’t let outdated monitoring hold you back — discover how PQE can help you meet the latest international standards.
