Harmonic suppression guideline
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
guideline for household appliances and general-purpose
products" and other models are covered by "Harmonic
suppression guideline for consumers who receive high
voltage or special high voltage". However, the general-
purpose inverter has been excluded from the target
products covered by "Harmonic suppression guideline for
household appliances and general-purpose products" in
January 2004 and all capacities of all models are now
target products of "Harmonic suppression guideline for
consumers who receive high voltage or special high
voltage".
⋅ 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

Make a judgment based on "Harmonic
suppression guideline for consumers who 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.

Outgoing harmonic current = fundamental wave current (value converterd from
received power voltage)
× operation ratio × harmonic content
⋅ Operation ratio: Operation ratio = actual load factor × operation time ratio
during 30 minutes
⋅ Harmonic content: Found in Table.
