Direct Ethernet Connection
•
•
•
•
Probably the easiet connection
method.
Requires either a cross-over
cable or a hub/switch.
Static IP addresses must be set
in the HDPQ and the PC.
Third party VNC software
required.
© 2015 by PowerCET Corp, All rights reserved.
27
Ethernet Direct IP Connection
•
•
•
•
Make certain that the ethernet
address is as shown.
Gateway and DNS server
addresses not required for direct
connection. Gateway and DNS
would be required to get data
through switches and routers.
Use local Area Connection
properties to assign a static IP in
the PC. Use an address that is
close to the HDPQ address.
Suggested address is
–
–
–
•
IP Address: 192.168.0.20
Subnet Mask: 255.255.255.0
Default Gateway: 0.0.0.0

Auto Detect - PQ & Energy/Demand
•
•
Power Quality and
Energy/Demand use the same
auto detect system to configure
the monitor.
Thresholds and waveform
capture are automatically set by
the monitor.
© 2015 by PowerCET Corp, All rights reserved.
49
Auto Detect – Scope & Phasors
•
•
•
Auto detect shows circuit
configuration.
Once the auto detect is finished,
phasor display can be check to
verify that polarities are correct.
Scope displays real time
waveforms.
© 2015 by PowerCET Corp, All rights reserved.
50
Auto Setup - PQ & Energy/Demand
•
•
•
•
If current is desired, then enable
current probes and select the
correct type.
Check the setup summary to verify
that settings are what is needed.
Press green start button to bring up
the next monitoring mode screen.
The procedure is the same for PQ
and Energy/Demand.
© 2015 by PowerCET Corp, All rights reserved.
51
Wizard Setup
• Wizard setup provides step by step control of monitoring processes. • Scope and phasors can be viewed directly. 52
Wizard Probes & Scaling
© 2015 by PowerCET Corp, All rights reserved.
53
Wizard Wiring Configuration
•
•
•
Wiring configuration wizard
detects circuit.
One can manually set the wiring
configuration.
Configuration screen shows
wiring diagram and phasors.
© 2015 by PowerCET Corp, All rights reserved.
54
Wizard Nominal & Frequency
•
•
•
•
Computed values may vary if
the monitor is configured in
advance.
Profile indicates whether
tracking will be standard for
normal utility monitors, fast for
local generators, or internal.\
Standard tracking has a tight
frequency tolerance and slow
response (0.01Hz/second).
Selecting Fast tracking
(0.1Hz/second) will change the
tracking range.
© 2015 by PowerCET Corp, All rights reserved.
55
Wizard Monitor Modes
•
•
•
•
•
If current probes are not
enabled, then Inrush and Motor
Quality will be grayed out.
PQ can be monitored by IEEE
or IEC definitions.
The threshold for an interruption
in IEEE Std 1159 is 10% of
nominal while in IEC 61000-4-30
it is 1% of nominal.
Fault recorder is voltage
triggered and will record voltage
disturbances sequentially.
There are many more
monitoring modes available in
Wizard than in the Auto Mode.
© 2015 by PowerCET Corp, All rights reserved.
56
Wizard Trigger Limits
• Every sub‐category must be used to fully take advantage of the monitors abilities.
57
Wizard Trigger Limits - RMS
•
•
•
ABC does not group channel D
– normally D is used for N/G.
Percentage of nominal (%
nominal) is an easy way to set
limits if given voltage range in
percentage.
Current limits are set separately.
© 2015 by PowerCET Corp, All rights reserved.
58
Wizard Waveform Capture
•
•
•
Default is to only capture
waveforms for the trigger
channel – voltage or current.
Simultaneous cross channel
waveform capture regardless of
the trigger channel.
All channels and channel D is
the preferred configuration to
capture everything possible
associated with an event.
© 2015 by PowerCET Corp, All rights reserved.
59
Wizard – Timed Intervals
Timed intervals can be reduced to improve data granularity.
• Waveform snapshot is important because waveforms not associated with a trigger are captured and therefore may better reflect normal conditions.
• Flicker is measured to European standards. •
60
Wizard – Journal Limits
Journal limits provides an ability to perform threshold driven logging functions.
• Unless there is a specific function that is desired, the best practice is to disable all. • Otherwise, the many, many journal entries will eat monitor memory. •
61
Wizard – Peak Transients
•
•
•
•
•
Peak transient captured with the
512 sample per cycle digitizer.
ABC the same for voltage and
current. Channel D is set
separately.
Check Enable Automatic Limit
Incrementing to set limit trigger
channel settings to autothreshold mode.
Set Pre/Post capture. Default is
2 cycle pre and post.
Set the same as RMS provides
continuity of waveform capture.
© 2015 by PowerCET Corp, All rights reserved.
62
Wizard – Waveform Transient
•
•
•
•
•
Waveform transient is really
waveshape difference.
It is useful in detecting notches
in waveforms.
This feature can also eat up
memory very rapidly.
Automatic limit incrementing is
recommended unless the
feature is disabled.
Again, one must set Pre/Post
waveform capture if longer pre
or post capture is desired.
© 2015 by PowerCET Corp, All rights reserved.
63
Wizard - Set RMS DIFF Transients
•
•
•
•
•
•
RMS deviation detects changes in
RMS content from the present cycle
to the previous cycle.
Again, in dynamic environments this
feature can fill memory rapidly.
Automatic limit incrementing can
reduce memory fill.
This is a great feature to capture
changes in RMS current associated
with equipment cycling.
It can also detect the effects of
harmonic voltages or currents
because the RMS content changes.
As usual, one must change pre/post
capture if wider capture is desired.
© 2015 by PowerCET Corp, All rights reserved.
64
Wizard – HF Transients
•
•
“The high frequency transient
detection algorithm calculates the
rms energy of the waveform in an
80 usec window (not including the
low frequency signal) and compares
that value against the threshold to
determine if a trigger occurred. If so,
the prior 80 usec window, the
triggered window, and three past 80
usec windows are saved. If triggers
occur in every window, up to 1 cycle
worth of data is saved.”
“For high frequency transients, only
a maximum of 1 cycle of data is
saved.”
•
High frequency transients are
captured with the 1MS/second
digitizer.
–
–
–
–
It does not work on channel D.
Cross channel triggering does not work.
There is no user selectable pre/post
waveform capture.
This feature is only available on Xplorer
and Xplorer 400.

65
Wizard - Finalize
•
•
•
Start/stop on specified time and
date is very valuable for
efficiency studies. The kWH
values of a transformer or UPS
can be accumulated.
Setup summary can be viewed.
Manage memory is easily
accessed.
© 2015 by PowerCET Corp, All rights reserved.
66
Wizard – Start Monitoring
• At the end of the Wizard setup, the monitor can be used as monitor or as a meter. 67
Other Wizard Monitoring Modes

69
Wizard – Fault Recorder
•
•
•
Fault recorder is voltage trigger
oriented.
Default pre/post cycle capture is
much longer than normal.
Essentially, the voltage fault
recorder will capture an event
and then rearm and wait for the
next trigger.
© 2015 by PowerCET Corp, All rights reserved.
70
Energy & Demand Audits
•
•
•
•
•
•
•
Billing Cycle has a calendar that allows one to select the start Day & Month.
Click on Start of Week to toggle through the days of the week.
User enters carbon footprint – the software does not provide a default.
CO2 units – toggles between lb‐CO2 and Kg‐CO2.
Demand units toggles between Watts, VA & Var.
User enters billing rate – there is no default value.
Billing current toggles between USD and Euro.
71
Long Term Timed Reading
•
•
Set the instrument to use
periodic measurements only.
This setting is used for longterm statistical studies and
benchmarking field-based
equipment testing and
evaluation. No triggers are set
so only trended values are
available.
You can enable waveform
snapshot but that does take up
memory.
© 2015 by PowerCET Corp, All rights reserved.
72
Continuous Data Logging
•
Sets the instrument to log rms
and power values once per
second until memory is filled or
for a specified time period.
© 2015 by PowerCET Corp, All rights reserved.
73
Voltage Compliance
•
•
•
The Quality of Supply is an analysis of the voltage per EN50160 which specifies that various parameters must be within a specified percentage for 95% of the time.
The seven parameters required by EN 50160 to determine QOS compliance are: Power Frequency, Supply Voltage Variations, Rapid Voltage Changes, Supply Voltage Unbalance, Harmonic Voltage, Interharmonic Voltage, and Mains Signaling.
“EN50160 Strict Compliance monitoring is selected by default. Press to enable/disable miscellaneous option Islanded. Islanded means isolated from the power grid. Islanded is disabled by default, indicating that the system being monitored is synchronized to the grid.”
