Troubleshooting
The PowerXplorer PX5-400’s unique annunciator “report card” provides instant
power quality answers in the field. A wide range of power monitoring data is
collected, analyzed and tabulated in color-coded categories to quickly identify areas
of concern, which are identified in
red. Drill down for more detailed
information by simply touching the
intuitive touch screen to locate the
source and pinpoint the root cause
of power quality disturbances.
The PowerXplorer ® PX5-400 was designed specifically for measuring and monitoring power on both 50/60 and 400 Hz power systems on ships,
aircraft, submarines, and the testing of equipment used on such. This unique instrument integrates the most advanced feature set available in
a power monitoring instrument, with automated setups and an easy-to-navigate, color graphical user interface. With high-speed sampling and
data capture (down to 1 microsecond/channel), this 8-channel workhorse simultaneously captures and characterizes thousands of parameters,
using a range of standard and customizable operating modes. The PowerXplorer PX5-400 collects data at 256 samples/cycle/channel, is
designed for both AC and DC applications, and meets MIL-STD-1399, IEEE 1159, IEC 61000-4-30 and EN50160 standards.
Mil Standard 1399 Testing
This interface standard for shipboard systems is the approved testing protocol for
naval sea standards and all relevant departments within the US DOD. The electric
power system serves a variety of user equipment including aircraft elevators,
communication systems, weapon systems and computers. The testing protocol is
used to verify compatibility with a
prescribed list of characteristics and
tolerances including transients, sags
and spikes, unbalance, frequency
tolerances and harmonics.
Recommended testing apparatus – a
voltmeter, frequency meter,
oscilloscope, harmonics meter, and
current transformers – can all be
replaced with one instrument, the
PowerXplorer PX5-400.
Power Measurement
Equipment being used in these applications must be tested in all operating modes,
including 400 Hz, to ensure that critical test and operational equipment fits with the
power supply. The PowerXplorer PX5-400 collects a range of parameters – from
load-related factors such as watts,
VA, VAR, frequency instability, power
factor and load excursions – to
power quality information including
sags, swells, transients and
harmonics. Users can select the
length and mode of data collection,
including troubleshooting, data
logging, power quality surveys,
energy and load balancing.
Fast Transient Capture
The PowerXplorer PX5-400 uses digitized high-speed sampling to capture and
analyze microsecond-wide transients (Dranetz 658-like and BMI 8800-like).
Transients, generated by fast-switching electronics, computer systems, aircraft
components, and load transfer are
immediately characterized as
impulsive or oscillatory and detailed
for further analysis. The
PowerXplorer PX5-400 delivers a
full profile, with events time
stamped to the millisecond of the
entire transient, to pinpoint the
exact source and cause of the event.
Power Quality Diagnostics
The PowerXplorer PX5-400 has a built-in event characterizer that labels events to
directly support troubleshooting and the gathering of survey data – for improving
power quality and equipment reliability, as well as for matching the requirements
and susceptibilities of that
equipment to the incoming supply.
Plus, the PowerXplorer PX5-400
captures detailed harmonics,
interharmonics and subharmonics
to effectively troubleshoot the
complex problems caused by
these events.
Equipment Testing
Evaluating and testing the performance of military components and computerized
systems under true operating conditions – 400 Hz or other – is key to ensuring a
successful mission. The PowerXplorer PX5-400 incorporates advanced features
such as RMS triggers, advanced
transient capture, and cross
triggering between channels to
ensure that all equipment is
working properly. Plus, real time
reading observing during testing,
startup and maintenance enable
users to see results and tweak
equipment on-the-fly.

Data can be viewed in real time using scope mode, meter
mode, event mode, harmonics spectrum or phasor diagrams.
Data is captured on a memory card for analysis, trending,
visualization and reporting using industry-leading DRAN-VIEW ®
software. DRAN-VIEW makes it simple to trend events, correlate data, analyze
worst-case scenarios, see frequency fluctuations, generate custom reports, and
understand complex issues such as transients and harmonics.
