PA9PLUS
Portable Power Quality Analyzer
DESCRIPTION
The new Megger PA9Plus is the latest innovation of
the successful PA-9 Power Quality Analyzer platform. It
incorporates newly enhanced key features including a
faster Digital Signal Processor (DSP) to support continually
evolving capabilities, a full 12 MB of nonvolatile internal
memory and standard auxiliary power input capabilities.
To address worldwide requirements and applications,
the PA9Plus is CE marked, supports several international
languages, and adheres to applicable European and
North American standards (EN50160, IEC61000-4-15,
IEEE1159, IEEE519), including automatic phase lock loop
synchronization of input frequencies ranging from 20 Hz
to 70 Hz, flicker measurements and recording, and out of
limits/frequency trending.
The optional removable memory capabilities allows
internally recorded data to be copied directly to an external
standard compact flash card using the same technology
available with most of today’s digital cameras. This means
that without a computer on site, data can be manually
or automatically copied from the instrument to external
memory cards, increasing the effective instrument memory
storage to the size of the card used. Similarly, new
configuration setups may be programmed in the same,
simple manner.
The standard software has been enhanced to fully support
the new functionality and is included at no cost with every
PA9Plus purchased. A new, optional report generator
has also been developed to support your customized
documentation/reporting needs.
The PA9Plus records power quality and power flow
information simultaneously. The recorded information can
be viewed via the built-in graphics display, downloaded to
a computer using the serial interface and optional modem,
or transferred using the optional removable Flash Memory
Module.
Megger offers a comprehensive line of self-powered (no
batteries required) flexible and clamp-on current probes
for use with the entire PA-9 Series. If you would prefer to
use your own probes, simply order the applicable Megger
adapter.
Power Quality
n The PA9Plus has a sample rate of 256 samples/cycle for
all input channels and harmonic analysis through the
63rd harmonic.
n Long-term (days/weeks/months) recording of voltage/
current RMS values with a response time as fast as every
cycle.
n Captures pre-fault and post-fault waveforms.
n Reports out-of-limits events.
