 Harmonic suppression guideline
Inverters have a converter section (rectifier circuit) and generate a
harmonic current.
Harmonic currents flow from the inverter to a power receiving point via
a power transformer. The Harmonic Suppression Guidelines were
established to protect other consumers from these outgoing harmonic
currents.
The three-phase 200V input specifications 3.7kW or less are
previously covered by "Harmonic Suppression Guidelines for
Household Appliances and General-Purpose Products" and other
models are covered by "Harmonic Suppression Guidelines for
Consumers Who Receive High Voltage or Special High Voltage".
However, the transistorized inverter has been excluded from the target
products covered by "Harmonic Suppression Guidelines for Household
Appliances and General-Purpose Products" in January 2004 and
"Harmonic Suppression Guidelines for Household Appliances and
General-Purpose Products" was repealed on September 6, 2004.
All capacity and all models of general-purpose inverter used by specific
consumers are covered by "Harmonic Suppression Guidelines for
Consumers Who Receive High Voltage or Special High Voltage"
(hereinafter referred to as "Specific Consumer Guidelines").

Harmonic Suppression Guideline for Consumers Who Receive High
Voltage or Special High Voltage
This guideline sets forth the maximum values of harmonic currents
outgoing from a high-voltage or especially high-voltage consumer who
will install, add or renew harmonic generating equipment. If any of the
maximum values is exceeded, this guideline requires that consumer to
take certain suppression measures.
Users who use models other than the target models are not covered by
the guideline. However, we ask to connect an AC reactor and a DC
reactor as before.
For compliance to the "Harmonic Suppression Guideline for
Consumers Who Receive High Voltage or Special High Voltage"
For compliance to "Harmonic suppression guideline of the general-
purpose inverter (input current of 20A or less) for consumers other than
specific consumers" published by JEMA

Receive High Voltage or Special High Voltage"
issued by the Japanese Ministry of Economy,
Trade and Industry (formerly Ministry of
International Trade and Industry) in
September 1994 and take measures if
necessary. For calculation method of power
supply harmonics, refer to materials below.
