THE MOST STRINGENT STANDARDS ON POWER QUALITY MEASUREMENT METHODS

Power Standards Lab is the only reference lab that offers a complete service to guide you and certify your instruments according to IEC 61000-4-30 Ed3.

Edition 3 of the standard was published in Feb 2015 (Edition 2 is now obsolete).

The certification testing is performed in compliance with IEC 62586-2 “Power quality measurement in power supply systems – Part 2: Functional tests and uncertainty requirements”

POWER STANDARDS LAB PROVIDES THIRD-PARTY TESTING AND CERTIFICATION SERVICES FOR THE BEST POWER QUALITY INSTRUMENTS IN THE WORLD

We approach the certification process as fellow engineers, not policemen. Almost every instrument we’ve tested has required various firmware adjustments to pass, and we’re glad to help your engineers understand exactly what’s required.

PSL Test Reports are detailed technical documents that are intended for use by our client’s engineers. PSL Certificates are straightforward declarations by a trusted third party (PSL) that an instrument meets certain requirements. PSL Certificates are generally distributed by our clients to their customers.

Upon successful completion of a 61000-4-30 Compliance Report, PSL will issue a certificate for Performance Class A or Class S. In some cases, a single certificate may include different classes of performance for different parameters.

The Certificate applies to all instruments of the tested type or design; it is not necessary to re-test or certify each instrument.

WHY USE 61000-4-30?

More and more customers and end-users around the world require a PSL Class A certification for all their new PQ measurement instrument purchases.

This standard ensures that different PQ instruments use the same definitions, and measurement techniques, for various power quality parameters: sags/dips, swells, frequency, harmonics, flicker, etc.

Older, non-compliant instruments often use their own definitions. As a result, two non-compliant instruments may produce very different readings for the same event.

WHAT IS IEC 61000-4-30 ED3:2015?

IEC 61000-4-30:2015 defines the methods for measurement and interpretation of results for power quality parameters in a.c. power supply systems with a declared fundamental frequency of 50 Hz or 60 Hz. Measurement methods are described for each relevant parameter in terms that give reliable and repeatable results, regardless of the method’s implementation.

This standard addresses measurement methods for in-situ measurements. Measurement of parameters covered by this standard is limited to conducted phenomena in power systems. The power quality parameters considered in this standard are power frequency, magnitude of the supply voltage, flicker, supply voltage dips and swells, voltage interruptions, transient voltages, supply voltage unbalance, voltage harmonics and interharmonics, mains signalling on the supply voltage, rapid voltage changes, and current measurements.

Emissions in the 2 kHz to 150 kHz range are considered in Annex C (informative), and over- and underdeviations are considered in Annex D (informative). This third edition cancels and replaces the second edition published in 2008

Parameters include:

  • Power frequency
  • Magnitude of supply voltage
  • Flicker
  • Supply dips/swells
  • Voltage Interruptions
  • Unbalance
  • Harmonics
  • Interharmonics
  • Mains signaling
  • Under- and over-deviation

New in edition 3

  • Rapid voltage changes
  • Flicker class F1
  • Measurements in the 2 kHz-150 kHz frequency band
  • Magnitude of the current
  • Current unbalance
  • Current harmonics
  • Current interharmonics
  • Recording of current along with voltage during events

What is new in Edition 3
Edition 3 cancels and replaces the Ed2 published in 2008. Edition 3 has introduced methods for measuring rapid voltage changes (RVC), currents (amplitude, harmonics, interharmonics, current recordings during events and unbalance), informative methods to measure in the 2 kHz-150 kHz frequency band

There are two classes of performance:
Class A
Instruments that meet Class A performance requirements of this standard, when connected to the same signals, will produce the same results. Class A instruments must meet the highest performance and accuracy requirements in the standard.

Class S
Instruments that meet Class S performance requirements are useful for statistical surveys and contractual applications where there are no disputes. Accuracy and performance requirements for Class S are less stringent than Class A.
