Energy & Demand Audits
: This setup can be used to conduct complete demand and
energy audit of a facility, a distribution circuit or a single piece of equipment. It can
monitor demand and energy parameters for energy audits, efficiency studies and cost
reduction programs. It can also be used to carry out long-term statistical studies to
establish baselines and perform field-based equipment testing and evaluation for
commissioning and maintenance.
Long-term Timed Recording, Demand, Energy
: Performing a statistically valid power
quality energy survey requires the capture of a set of basic data over an extended period
of time. HDPQ Xplorer is designed to facilitate long-term monitoring by collecting
min/max/avg data at each predetermined interval in order to perform post-process
harmonic and other events analysis. HDPQ Xplorer is also designed to be left
unattended in the field, recording statistically representative data for long-term
analysis. Using the Dranetz lockable portable case option or other available enclosures,
power quality studies can be carried out in harsh weather environments.
Continuous Data Logging, Demand, Energy
: This logs the rms and power values once
per second for totally gapless logging. Cyclic triggers are disabled. No waveforms are
recorded under this monitoring mode.
Voltage Compliance (EN50160 Power Quality)
: Voltage Compliance monitors and
reports Quality of Supply (QOS) compliance as specified by the EN standard. The
seven parameters required by EN50160 to determine QOS compliance are: Power
Frequency, Supply Voltage Variations, Rapid Voltage Changes, Supply Voltage
Unbalance, Harmonic Voltage, Interharmonic Voltage, and Mains Signalling. Other
standards can be utilized by changing appropriate setup or parameters.
Motor Quality
: Automatically sets up the parameters that affect the operation of
motors. Motor parameters include True Power Factor, Horsepower, and Derating
Factor, among others.
