PA9PLUS

Portable Power Quality Analyzer

FEATURES AND BENEFITS

The maintenance-free design provides significant time

savings with each installation. With the capability of
preprogramming up to 64 internal setups in advance, the
PA9Plus is always ready. Simply select from any of the
sample or user-defined recording configurations/ setups
and begin the analysis. Setups may also be imported via
the removable memory option.

The PA9Plus is typically self-powered from the

unregulated voltage on the first input channel (90-600 V
ac at 20-70 Hz, or 110-600 V dc). This means that it can
be used virtually anywhere since a well-regulated 120
or 240 V ac power source is not required. The auxiliary
power input feature allows an alternative to self-power
from a 10th, non-recording input source, effectively
eliminating the small burden required to power the
PA9Plus. This feature also negates any turn-on delays
associated with some monitoring applications such as
high-speed motor start studies.

A large, backlit LCD confirms setup information and

real-time status, phasors, frequency, harmonics, harmonic
power, voltage, current, per phase and total power/
energy data, and minimums/maximums by phase.
From data already recorded, charts of trended voltages,
currents, waveform graphs, and reports of historical out-
of-limits information by event type may be viewed.

The newly enhanced MEGPA9IEC software for setup,

configuration, communications, charting, and reporting
continues to be included at no cost with every PA9Plus
purchased. Optional enhanced report generation
software, METREPORT, may also be purchased
separately for creating custom-tailored reports.

MEGPA9IEC SOFTWARE FOR WINDOWS

MEGPA9IEC is a simple, intuitive, menu-driven software
package for use with both the new and existing PA9Plus
Power Quality Analyzers. This software, provided at no
charge to Megger customers, incorporates an instrument
firmware upgrade feature for field-updating your PA9Plus
to the newest capabilities.

Retrieve Only the Data That Matters

MEGPA9IEC now includes a remote test log function to
preview charts, events, reports, and waveforms prior to
actual download. This preview function also includes the
capability to select and download only the data content and
time frame relevant to the investigation being performed,
thus dramatically reducing the download time required.

Software Features

This software offers many powerful features specifically
designed to save time via:

Easy, fill-in-the-form instrument setup and configuration

Advanced local and remote connection capabilities

Locate specific data files using the integrated search

function

Generate charts of voltage/current and demand data

Perform harmonic and waveform analysis

Chart individual harmonics, THD, TDD, frequency, and

imbalance

Zoom/unzoom on specific graphical areas of interest

Choose from several built-in analysis reports

Quick Recorder Setup

With Megger MEGPA9IEC, the PA9Plus can be set up for
different test conditions in a matter of seconds. By simply
filling in a form, the operator chooses which phases to
record, the corresponding out-of-limit values, which
statistics to save (minimum, RMS, and/or maximum), etc.
For added convenience, the software provides default
configurations for use as templates in creating customer-
specific setups. Further, the software computes the
maximum recording time based upon the selections made.
Once the PA9Plus is configured for a test, it will retain this
setup information until changed. Setup files may also be
saved for re-use, or transported amongst instruments using
the optional removable memory card.

Harmonic Analysis

The PA9Plus records data for harmonic analysis and Megger
MEGPA9IEC provides the following on that data:

Charts of actual waveforms analyzed

Bar Chart of the harmonics magnitude and signature for
any selected waveform cycle through the 63rd harmonic

Harmonic Analysis Report for the selected waveform
cycle

Harmonic Trending – Total Harmonic Distortion (THD),
Total Demand Distortion (TDD), and all individual
harmonic voltages and currents through the 63rd

IEC Flicker – both PST/PLT measurement and recording

Flicker Trending per IEC61000-4-15 and EN50160
