Description
ON = the instrument will record the values of the
selected voltage and current harmonics.
For example: if the following parameters are
selected:
a) Phase Voltage 1 and 2, Thd, Harmonics 1, 3, 5.
b) Phase Current 2 and 3, Thd, Harmonics 3, 5, 7.
The instrument will record:
a) The Phase Voltage 1 and 2, Thd and Harmonics
1, 3, 5 of the Phase Voltage 1 and 2, but will not
record anything about Phase Voltage 3.
b) The Phase Current 2 and 3, Thd and Harmonics
3, 5, 7 of the Phase Current 2 and 3, but will not
record nothing about Phase Current 1.
OFF = the instrument will not record any voltage
or current harmonics.
ON = the Instrument will record Voltage Sag and
Surge.
OFF = the instrument will not record Voltage Sag
and Surge.
RMS value of the voltage of phase 1, phase 2,
phase 3 respectively, values of the phase-to-phase
voltages 1-2, 2-3 or 3-2 and 3-1.
Voltage Total Harmonic Distortion, DC Compo-
nent, 01 to 49 Harmonics
RMS reference value for Voltage used in Voltage
Anomalies detection (Voltage Sag and Surge).
The Reference is:
a. Voltage Phase to Neutral for Single
Phase and 3PH4W.
b. Voltage Phase to Phase for 3PH3W
High and Low Voltage Percent threshold used in
Voltage Anomalies detection (Voltage Sag and
Surge).
RMS value of the current of phase 1, phase 2,
phase 3 and neutral respectively
