• The former Agency of Natural Resources and Energy of Ministry of International Trade and Industry (present
Ministry of Economy, Trade and Industry) established higher harmonics suppression guidelines in September
1994.
(1) Drivers rated 4kW or lower are subject to “Higher Harmonics Suppression Guidelines for Home Electric and
General Purpose Appliances”.
(2) Drivers rated over 4kW are subject to “Higher Harmonics Suppression Guidelines for High Voltage and Special
Customers”.
• The Ministry of Economy, Trade and Industry strongly demands manufacturers to enforce measures to curb
harmonics.
In order to comply with the established regulatory level, connect a power-factor improvement reactor (L) to drivers
of 4 kW or lower. For drivers of over 4kW, determine the level of harmonics according to the guideline and take a
suppression measure, as appropriate.
