Power Quality Analysis
Utilizing digital signal processing (DSP) technology, the Acuvim II series meter
provides high accuracy power quality analysis and supports remote monitoring
via the Ethernet module. The meter continuously updates metering results and
allows users to access the meter online to monitor parameters such as voltage
and current THD, harmonics, voltage crest factor, current K factor, and voltage
and current unbalance factor etc.
Data Logging
The Acuvim IIR/IIE/IIW meter contains 8 megabytes of onboard memory for data
logging and historical trending. Since the meter contains a real-time clock, all
events and logged data will be time stamped.
Time of use (TOU-Acuvim IIE)
User can assign up to 4 different tariffs (sharp, peak, valley and normal) to
dierent time period within a day according to the billing requirements. The
meter will calculate and accumulate energy to dierent taris according to the
meter’s internal clock timing and TOU settings.
Power Quality Event Logging
When a power quality event happens, such as voltage sag and swell, etc, Acuvim
IIW will record the timestamp and the triggering condition of the event. It can
save up to 50, 000 power quality events.
Waveform Capture
Acuvim IIW contains another 8 megabytes of on board memory for power
quality event logging and waveform capture. Acuvim IIW can record 100 groups
of voltage and current waveforms. It logs at 64 points per cycle. It provides
the waveform record of 10 cycles before and after the triggering point. It also
supports a settable triggering condition.
