Using the Harmonic Current Analysis Function

You can perform harmonic analysis of the output current. A simplified measurement method is used, so this method does not conform to standards such as IEC. For measurements that conform to the standards, use the Harmonic/Flicker Analyzer KHA3000.

If the period is set greater than the aperture time, correct measurements cannot be made.

The harmonic current analysis function is valid in AC mode.

Press OTHERS (SHIFT+MEMORY) and then FFT (F5) to set the order and the unit.

During single-phase, three-wire output or three-phase output (optional), press OTHERS (SHIFT + MEMORY), FFT (F5), and then 1/2 (F6), and then press the key that corresponds to the phase that you want to set.

 

Item	Description	Valid mode
ALL	Selects all the orders	AC
ODD	Selects all the odd-numbered orders
EVEN	Selects all the even-numbered orders
AMPER	Sets the unit that is used to display the harmonic components when the harmonic component of each order is being displayed as a current
PCT	Sets the unit that is used to display the harmonic components when the harmonic current is being displayed as a percentage with 100 % representing a current that has no harmonic current components
U*1	Selects the U phase
V*1	Selects the V phase
W*2	Selects the W phase
