Acuvim-L
The 2
nd
screen: Phase current THD: THD_I1, THD_
I2, THD_I3.
As shown in Fig 3-23, THD of three phase current,
THD_I1=1.89%, THD_I2=1.83%, THD_I3=1.85%.
Press “H” key, go back to the 1
st
screen.
Note:
When voltage wiring mode is set to 1LN,
display only shows phase current THD: THD-I1. When voltage wiring mode is set
to 1LL, display only shows phase current THD: THD-I1 and THD-I2.
3.3 Statistics Display
For Acuvim-AL,BL,CL,DL,ELPress “H” and “E” simultaneously to enter the statistic
display mode. Maximum and minimum value for metering parameters are
demand, voltage and current unbalance factor, and individual voltage and
current harmonic. Press “H” and “E” simultaneously again to exit to the real-time
metering mode.
Note:
Acuvim-EL and Acuvim-KL will not show harmonic contents.
3.3.1 Display Max and Min of the voltage and current and Peak Demandof
current .(AL, BL, CL, DL, EL)
Press “V/A” key under the statistics display mode
to display the Min and Max value of voltage,
current and current demand.
The 1
st
screen: Max value of phase voltage. The
“Max” icon is shown on the top of screen.
As shown in Fig. 3-24, U1_MAX=380.3 V, U2_
