HIOKI Launches 'IEC Harmonic/Flicker Measurement' License for Power Analyzer PW4001

Power Analyzer PW4001 equipped with IEC Harmonic/Flicker Measurement Function PW9006

HIOKI (HIOKI E.E. CORPORATION: Ueda City, Nagano Prefecture, President: Takahiro Okazawa) will launch the 'PW9006' license on June 10, 2026. This license adds IEC harmonic and flicker measurement functions compliant with international standards IEC 61000-4-7 (harmonic and interharmonic measurement standard) and IEC 61000-4-15 (flicker measurement standard) to the PW4001 power analyzer, which was released in 2025. By introducing this license, highly reliable 'IEC harmonic/flicker measurement' data compliant with international standards can be obtained in research and development and certification evaluation across a wide range of fields, including industrial equipment, electronic devices, home appliances, and automotive-related equipment.

Background of Development: Importance of Standard-Compliant Measurement

With the widespread use of various electrical and electronic devices, their impact on the power grid has become an issue. In particular, 'harmonics' and 'flicker' (voltage fluctuations) generated by devices can hinder stable power supply and the normal operation of other equipment. IEC 61000-4-7 (*1) and IEC 61000-4-15 (*2) are international standards that define methods for measuring such harmonics and flicker.

In harmonic and flicker measurement, testing in a manner compliant with standards is a crucial element to ensure product reliability and smoothly proceed with certification and market introduction.

This optional license realizes harmonic and flicker measurements compliant with these measurement method standards (IEC 61000-4-7/-4-15) for the Power Analyzer PW4001.

The acquired measurement data can be used to evaluate conformity to various limit value standards.

*1 IEC 61000-3-2, IEC 61000-3-12: Standards specifying limits for harmonic current emissions from equipment

IEC 61000-4-7: A standard defining the measurement methods required by these harmonic limit standards

*2 IEC 61000-3-3, IEC 61000-3-11: Standards specifying limits for voltage fluctuations and flicker generated by equipment

IEC 61000-4-15: A standard defining the measurement methods required by these flicker limit standards

Product Overview

By applying this license, harmonic/interharmonic analysis and flicker measurement functions compliant with IEC 61000-4-7 and IEC 61000-4-15 can be added to the existing power analyzer 'PW4001'.

This allows for the acquisition of highly reliable 'IEC harmonic/flicker measurement' data compliant with international standards in R&D and certification evaluation across various fields such as industrial equipment, electronic devices, home appliances, and automotive devices.

Main Applications

Acquisition of harmonic/flicker measurement data compliant with measurement methods (IEC 61000-4-7/-4-15) required by IEC 61000-3-2, 3-12 (harmonic limit standards) and IEC 61000-3-3, 3-11 (flicker limit standards)

Harmonic/flicker measurement during the development and design stages of industrial equipment, home appliances, electronic devices, automotive equipment, etc.

Acquisition of data for certification applications and submission to third-party evaluation organizations

Standard compliance evaluation for product quality improvement and technical data management

Features of the Optional License

Harmonic, interharmonic, and flicker measurement functions compliant with IEC 61000-4-7/4-15 can be added to the power analyzer PW4001.

It utilizes the high-precision power measurement performance of the power analyzer to improve the efficiency of R&D and evaluation tests.

The license is provided in two forms: a card describing the license code (physical card shipped) and a digital license issued after online purchase. Both can be easily introduced to an existing PW4001.
