Energy: These three meters show the total energy, apparent energy, and reactive
energy. The energy accumulators can be reset by pressing the reset button
.
Class A: You will find additional power quality parameters as defined in IEC
61000-4-30 Class A, the international standard for power quality measurement
methods.
Flicker: These meters show flicker according to IEC 61000-4-15 Edition 2
methods. P
inst
is the instantaneous flicker value for Incandescent Flicker. P
st
is the
short-term flicker, a statistical analysis of P
inst
after 10 minutes, synchronized to
real-time clock. P
lt
is the mean value of P
inst
over previous 2 hours, synchronized
to real-time clock.
Unbalance: These meters show the voltage unbalance and the current
unbalance. You can choose whether your PQube 3 calculates unbalance using the
ANSI C84.1 method, IEC method, or GB method in your Setup.ini file.
Harmonics: Use this screen to view every harmonic up to the 50
th
for both voltage
and current. Select one harmonic at a time. The selected harmonic applies to all
channels. (Harmonic values up to the 50
th
are recorded in your PQube 3’s CSV
files.)
