15 Appx. 6: Higher Harmonic Suppression Measure Guidelines
511
IB-1501229-F
15.1.1 Calculating the Equivalent Capacity of the Higher Harmonic Generator
As a principle, the higher harmonic suppression measure guidelines must be followed by the customer.
(1) Calculating the total equivalent capacity (Step 1)
Calculate the total equivalent capacity with the following expression.
Total equivalent circuit: Po =
Σ
• Ki • Pi
Ki
:Conversion coefficient (Refer to following table)
Pi
:Rated input capacity of each device
(Table 1) Rated capacity of each unit
(Note)
The rated capacity Pi above, is the value used to calculate whether the product corresponds to the higher
harmonic guidelines. Thus, the value will differ from the actual power facility's capacity.
(The power supply unit is not included.)
(Table 2) Circuit class and conversion coefficient for each unit
(Note)
This applies when an AC reactor is installed on the power supply unit.
(Table 3) Limit values for total equivalent capacity
If the total equivalent capacity Po exceeds the limit value given in (Table 3), proceed to "(2) Calculating the higher
harmonic current flow".
Measures are not required if the value is not exceeded.
