Variable reading Thd of voltage and current (harmonics orders option)
A page shows the total harmonic distortion of voltage and of current:
•
(Thd) total harmonic distortion of voltage L1 phase [Thd
1
]
•
(Thd) total harmonic distortion of voltage L2 phase [Thd
2
]
•
(Thd) total harmonic distortion of voltage L3 phase [Thd
3
]
•
(Thd) total harmonic distortion of current L1 phase [Thd
1
]
•
(Thd) total harmonic distortion of current L2 phase [Thd
2
]
•
(Thd) total harmonic distortion of current L3 phase [Thd
3
]
8 pages show the harmonic components (up to 31
st
) of voltage
and current of each line in numerical form.
Variable reading total harmonic distortion and harmonic components
of voltage and current (option).
6 pages of visualization of THD and harmonic components (up to 31
st
with
fundamental frequency 50-60Hz) of voltage and current of each line
expressed in numerical and graphic form. Once entering in the harmonic
analyzes page, it may be possible with the right + enter & left + enter keys
to page through the order of the harmonics up to the 31
st
. The pages show
the histograms, the order of the harmonic and value referred to the
fundamental.
