WiFi/BLE Module

The WiFi/BLE module enables the wireless connectivity. Wireless connectivity is the preferred
data transfer method when the Product is installed in hazardous environments, such as,
cabinets.

The WiFi/BLE module enables these features:

 Wireless data transfer to Energy Analyze Plus PC software.

 Time synchronization with NTP

 Remote control via Virtual Network Computing (VNC). See Remote Display for more

information about VNC.

A WiFi/BLE Module is included and pre-installed. If necessary, the module is removable or you
can install a module to upgrade a basic model.

To remove the adapter:

1. Open the protection cap of the WiFi/BLE module. See Figure 1.

Before You Start

4. Close the protection cap.

To u pg r a de :

1. Unscrew the two screws and dispose of the blind plate.

2. Insert the WiFi/BLE module into the correct slot.

3. Fasten the two screws.

4. Make sure the sealing area is clean and close the protection cap.

The WiFi/BLE module supports the connection to a WiFi infrastructure and direct connection
from a PC to the Analyzer. The module includes an internal antenna.

A router signal is sometimes weak due to factors such as obstacles, power, output, and
distance. The WiFi/BLE module supports an external 2.4 GHz/5 GHz WiFi antenna that can
boost the WiFi range of your signal for a more reliable WiFi signal.

Users Manual

An adapter cable (available from Fluke) connects the antenna to the installed WiFi/BLE module.
See Figure 2.

Figure 2. WiFi Antenna Connection

PN 5263915

Note

The antenna cable connects to the antenna with a SMA connector that has an outside
thread and a center receptacle (SMA female/jack). Former FCC regulations required
that WiFi equipment must use reverse polarity connectors. You must use an SMA male
plug to RP-SMA female adapter if the antenna uses a RP-SMA male connector with an
internal thread and center receptacle.

XW Warning

To prevent possible electrical shock, fire, or personal injury, use Product­approved measurement category (CAT) antenna cables when the Product is
installed in environment where wires or exposed metal parts provide access to
hazardous live voltage, such as, in cabinets.

GPS Time Synchronization

With a GPS antenna, the Analyzer has the best possible real-time accuracy of typically 1 ms
and complies to the time synchronization requirements of IEC61000-4-30 Class A.

To use GPS time synchronization:

1. Go to Instrument Setup > Time Synchronization Source and configure as GPS.

The GPS status on the Analyzer indicates an invalid time synchronization status and no
connection to the GPS receiver.

2. Attach the antenna cable to the GPS Input Connector. See Figure 3.

3 Phase Power Quality Analyzer

Before You Start

Figure 3. GPS Connection

PN 5263915

3. Connect the GPS antenna to the antenna cable.

A GPS antenna is available from third-party sources and must have these requirements:

 Satellite system: GPS, GLONASS. Support of both systems allows faster, more reliable

tracking.

 Antenna type: active (3.3 V) or passive

4. Position the antenna at a location with clear view to the sky.

Due to the extreme low signal strength of satellites, consider an outdoor location for a
reliable time synchronization. The acquisition takes approximately 1 minute until the GPS
receiver identifies enough satellites to use for the time synchronization. The GPS icon in
the status bar turns green when the GPS receiver provides reliable time synchronization.

If required, you can extend the connection to the GPS antenna with an additional antenna
cable that has an SMA plug and SMA socket. The total length should be <20 m.

3 Phase Power Quality Analyzer

Before You Start

iFlexi Current Probe

The iFlexi Current Probe works on the Rogowski coil (R-coil) principle that is a toroid of wire
used to measure an alternating current through a wire encircled by the toroid. See Figure 5.

The R-coil has advantages over other types of current transformers:

 It is not a closed loop. The second terminal is passed back through the center of the toroid

core (commonly a plastic or rubber tube) and connected along the first terminal. This allows
the coil to be open-ended, flexible, and able to be wrapped around a live conductor without
disturbing it.

 It has an air core rather than an iron core. It has a low inductance and can respond to fast-

changing currents.

 Because it has no iron core to saturate, it is highly linear even when subjected to large

currents, such as those used in electric power transmission or pulsed-power applications.

A correctly formed R-coil, with equally spaced windings, is largely immune to electromagnetic
interference.

Users Manual

Note

Make sure IPv6 is enabled on your Windows system.

Ethernet

Use a commercially available Cat 5 or higher Ethernet patch cable to connect the Analyzer to
your LAN (local area network). A communication over Ethernet requires that each device has a
unique IP address. Two options exist: Either a device obtains an address from a DHCP server
or the device uses a static, user-configured address.

The default setting of the Analyzer is to obtain an IP address from a DHCP server automatically.
The Analyzer allows a Ethernet point-to-point connection between the Analyzer and a PC. The
Analyzer has Auto-MDI-X support to switch automatically between 1:1 for a device-to-LAN
connection and cross-over mode required for a device-to-device connection. A cross-over
cable is not required. The Analyzer and PC self-assign IP addresses in the range of 169.254.x.x
automatically after the timeout to receive an IP address from a DHCP server expires.

Note

During the typical timeout of 1 minute, Windows shows the status “Identifying” in the
network status. Windows may show an exclamation mark in the network status icon
indicating that the connection does not provide Internet access. This is normal.

The Analyzer communicates with the Fluke Energy Analyze Plus software on these ports:

Type Port Number

TCP 80 (HTTTP)

TCP 443 (HTTPS)

TCP 18571

UDP 18572

The software installer for Energy Analyze Plus automatically adds exceptions to the Windows
firewall. If a third party firewall is used, add the ports and the application fea.exe to the
exception list.

Voltage and Current Ratio

If a voltage and current transformer is included in the measured circuit, you can choose a
multiplier so that the results appear in the correct engineering units, for example, kV or MW.

To set the ratio for phase voltage and neutral:

1. Select the primary ratio (which is then compared to 1).

The touchscreen number pad opens. When the ratio is expressed as 1000:25, the setting is
40:1. Most often the ratio is expressed with reference to 1.

2. To clear the default 1 in the display, tap .

3. Input the new number using the touchscreen number pad.

In the current ratio screen the default setting is Auto. In this mode the Analyzer adjusts
automatically to get the best measurement resolution. You can change the current range to a
fixed range that is dependent on the connected current flex or probe device. The Analyzer
automatically detects a connected device. Detection includes specific information about the
device such as the serial number and the calibration constant for the best results.

Flicker

The Flicker setting is adjustable to a selected nominal voltage value. This value enables the
correct evaluation of any recurrent small changes on the electrical system caused by other
loads connected to the power system in the local electrical system or on the power utilities
network.

The preferred setting is Match Nominal Voltage, which is the nominal voltage selected for the
Analyzer. Flicker is measured in accordance with the IEC 61000-4-15 standard.

K Factor

K Factor is a ratio that expresses potential energy losses experienced in transformers due to
harmonics and eddy current losses at the fundamental frequency. There are two methods to
make the K Factor: IEEE C57:110 and EN 50464-3/EN 50541-2. Selection of the method is
usually dependent on the selected type of K rated transformer specification. K rated
transformers are designed and built to alleviate the effects of harmonics that may increase the
temperature of the transformer. Other values selected in this screen include harmonics and

constants e and q. You can select the 40
constants e and q refer to eddy current loss at the fundamental frequency divided by the loss
due to a dc current equal to the RMS value of the sinusoidal current. This is an exponential
constant that is dependent on the type of transformer winding and frequency.

Event Trigger Settings

The capture of events requires trigger settings. A set of standard settings are enabled by
default. These triggers are to specify when a detailed RMS capture occurs in the Analyzer. The
1775 and 1777 models also include a waveform and transient capture as well as the detailed
RMS voltage capture.

The available settings are:

 Dip

 Swell

 Interruption

 Waveshape Deviation

 Transients

 Rapid Voltage Change

 Inrush Current

For more details about each of these event settings, see Glossary.

Dips and Swells. For dips and swells the capture is based on the RMS voltage expressed as a

percentage of the nominal voltage.

The defaults for these settings are 90 % and 110 %. This means that for a 230 V nominal the
voltage must drop by 23 V to capture, and a swell capture is triggered at 253 V. Hysteresis of
2 % is automatically assumed, this means that the event is considered to have ended if the 2 %
recovery within 90 % or 110 % of voltage is made. This setting ensures that multiple events are
not captured for a single event. The setting of this voltage is considered from a standard
averages period of 200 ms or a sliding reference is applied. This reference considers the last
10 cycles for 50 Hz or 12 cycles for 60 Hz.

Use a sliding reference where the nominal voltage can vary more freely. This is usually the case
in high voltage systems. When you apply the sliding reference, the Analyzer detects dips and
swells based on a voltage change relative to the actual rms voltage, rather than, the absolute
nominal voltage.

Interruptions. Interruptions are events when a total power loss is made at the load across all
measured phases. This could be a blown fuses, a breaker tripping, or utility power loss. In the
case of power loss, the default value is 5 % of the nominal voltage. You can increase this
voltage if the registration of the interruption is not correctly represented or if the electrical
system is supported for several cycles by inductive or capacitance effects in the system. An
automatic hysteresis of 2 % is applied.

Waveshape Deviation. The deviation of the waveform considers the consecutive waveform
based on sample-to-sample comparison of the waveform. The trigger starts when the
magnitude of each cycle is compared with the sample magnitude on the next cycle. This is
expressed as a percentage of the nominal voltage. The default setting is 10 % of voltage. To
activate this trigger, check the Trigger On box.

29

www.GlobalTestSupply.com

1773/1775/1777

Users Manual

Transients. If the model in use includes the transient feature, the trigger settings consist of
High, Medium, and Low. These settings are on values that are equivalent of 200 %, 100 % and
50 % of the nominal voltage superimposed on the voltage waveform at any point during the
cycle. In addition, there is a user selectable custom setting expressed as an absolute voltage.

With the 1777 Analyzer, select the sample rate of the transient capture as either 1 MHz or
20 MHz. The 1775 Analyzer defaults to the maximum sample rate of 1 MHz.

To activate this trigger, check the Trigger On box.

The Analyzer safely captures transients up to ±8 kV.

Rapid Voltage Changes. Quick transitions of voltage between two steady state voltages are
known as rapid voltage changes (RVCs). The capture trigger for RCVs is based on a
percentage of the nominal voltage. The event is captured when the arithmetic mean of
100/120 (50/50Hz) half cycle RMS value is below the set trigger limit.

Inrush Current. Inrush occurs when large loads or low impedance loads are connected to the
power systems. Examples are motors, transformers, and capacitive loads. During the
connection, the current draw can increase to 10x or more of the normal level. The threshold for
capture is set as an absolute level of the measurement of a half cycle RMS value.

The trigger must be turned on to be operable. The Analyzer adds a default hysteresis.

the triggering mechanisms.

Harmonics Grouping

The Harmonic Grouping selection at the bottom of the screen allows for a different method of
harmonics representation. The listed standards most frequently recommend Subgrouped
harmonic.

Note

Fluke recommends the Subgrouped setting unless there are special circumstances
why the other methods are applicable for the required test. A change to this grouping
method could lead to inconsistent results when making comparisons of other
measurements made at the same or other locations.

Select Done to exit the Harmonics Grouping screen.

Mains Signaling

Mains signaling, or ripple control, is a technique used by utilities to instruct revenue meters to
switch tariffs, turn on street lighting, or turn on other loads. The mains signaling selection
enables capture of two signal frequencies other than the system frequency. The frequencies
must be specified in the setup and between 110 Hz and 1600 Hz.

To set the Mains Signaling voltage:

1. Enter the value in the Frequency 1 and Frequency 2 fields.

After you enter the frequency, the Enable radio button is automatically checked as active.

2. Tap Done.

This measurement is increasingly rare. If you do not need this information, ignore the setup.
The selection is switched off as a default.

Note

See the Glossary for more information about these configuration effects and details of
the triggering mechanisms.

AUX

The auxiliary, or analog, inputs are dc inputs that have a physical socket on top of the Analyzer
reserved for ±10 V dc signals. These signals may be from transducers that output voltage or
current. Each analog input signal can be labeled to describe the signal along with the
applicable engineering units, such as V dc, V ac, I ac, °C, or Nm. Select a gain and an offset to
scale the 0 V to 10 V signal so that the display shows the correct values.

Measurement Configuration

This example considers an output of a temperature transmitter with 4 mA to 20 mA current
that represents 0 °C to 250 °C:

1. Feed the current through a 50 Ω resistor to convert the signal to a voltage of 0.2 V dc to
1Vdc.

2. Use the on-screen keyboard to input the name, Pressure, the units, and the mathematical
constants that change the 4 mA to 20 mA to pressure readings.

At 4 mA the voltage will be 0.2 V dc representing °C. At 20 mA the voltage will be 1 V dc
representing 250 °C. The span of the signal from 0 to 250 °C will be 0.8 V. To create a value
of 250 °C at full scale the signal is multiplied by 312.5 (250/0.8). As the 0 °C is 0.2 V dc, an
offset is applied, this offset is the difference between 250 and 312.5 which is 62.5.

3. Check the AUX box to enable the display and logging of the AUX input.

Before logging can start, review the Event Trigger Setting. This setting ensures a check is
made before the logging session starts and results in a session that delivers valid data every
time.

Note

To use this feature you will need to purchase the optional Models: Fluke 17XX AUX
Input Adapter Box that allows inputs of ±1000 V dc with 4 mm sockets or ±10 V dc with
push-in terminals.

PQ Logger Event Trigger Settings

The Event Trigger Settings are supplementary to the PQ Meter Trigger Settings and are used
for mains signaling only.

The trigger is based on a small percentage of the Nominal Voltage but only appear for
triggering at the frequencies selected in the mains signaling setup. The typical setting is 5 % of
nominal. The trigger must be enabled with the Trigger On radio button. (Most applications will
not need this trigger turned on.)

Other event trigger settings should also be reviewed. See Event Trigger Settings.

Session Settings

The Session Settings specify the duration of the logging session from an absolute date of
some unknown date in the future, the average period of each of the logged measurements,
and the details required for harmonics measurements. In addition, you can create a unique
name for the session and a description of the session that is included in all reports generated

Measurement Data Review

Measurement Data Review

The Analyzer has features for measurement data review in both the PQ Meter mode and the
PQ Logger mode. The PQ Logger mode also includes the PQ Health feature.

PQ Health

The PQ Health feature is available only in PQ Logger Mode.

When the PQ Logger Mode session starts, the Analyzer shows the overall PQ Health of the
electrical system as a summary of these parameters:

 Frequency

 Volta ge

 Harmonics

 Unbalance

 Flicker

 Mains Signaling

 Events (dips, swells and interruptions)

 Rapid Voltage Changes

 Waveform Deviations

The frequency, unbalance, and events have a single bar.

Voltage variations and voltage harmonics show as three bars that depend on the configured
topology. The length of a bar increases if the related parameter is further away from its nominal
value. The bar turns from green to red if a maximum allowed tolerance requirement is
surpassed. When the standard defines two limits for a parameter (for example, voltage
variations have a limit for 95 % of the time and a limit for 100 % of the time) the bar changes
from green to orange when the parameter surpasses the 95 % limit but does not exceed the
100 % limit.

The exact representation shown on this screen depends up on the Power Quality standard
chosen in the setup. See Power Quality Standard. As the measurement proceeds, the green
bars typically grow as they get to the allowable limit indicated with a dotted bar. If the values
start to exceed the 95 % or 100 % limits, the bars turn to yellow or red. This is an immediate
insight that there is a problem.

Often, the waveshape data does not show a strong indication of the event as the trigger is
based on an RMS value that occurs over many cycles. The RMS profile is chosen in the same
screen to show the limits for dips and swells. The profile indicates where the voltage was
outside of the limit. Colored markers indicate the minimum and maximum voltages from the list
that shows on the right of the screen. The display can be customized to show different
combinations of voltage and current by individual phase or multiple phases.

Harmonics

Voltage, current, and power harmonics show as either a percentage of the fundamental or
RMS values by phase. Harmonics are available as three types Integer harmonic from 0 to 50,
Inter-harmonics, and harmonics from 2 kHz to 30 kHz. Harmonics show as either bargraphs
with the % or RMS scale or in a live trend. This option shows the available bargraph form in the

Nominal Voltage. Select a nominal voltage from the list. If a voltage is not shown in the list,

enter a custom voltage. The nominal voltage is required to determine the limits for dips, swells,
and interruptions. When a voltage transducer is used, enter the nominal voltage on the primary
side of the transducer

Nominal Frequency. Set the nominal frequency to be the same as the power line frequency,

50 Hz or 60 Hz.

Voltage Ratio. Configure a ratio factor for the voltage inputs when a potential transformer (PT)
is in series with the voltage connections such as when you want to monitor a medium-voltage
network. The default value is 1:1.

Current Range. Configure the current range of the attached sensor:

 High Range

High Range is the nominal range of the attached current sensor. For example, 1500 A is the
nominal range on an iFlex1500-24.

 Low Range

Low Range is 1/10 of the nominal range of the attached current sensor. For example, the
low range of an iFlex1500-24 is 150 A.

 Auto

When set to Auto, the current range is set automatically and depends on the measured
current.

Note

Set the current range to Auto when you are not sure about the maximum current during
the logging session. A specific application can require you to set the current range to a
fixed range rather than Auto. This can occur because the Auto range is not gapless and
may lose too much information in the case of a highly fluctuating current.

Current Ratio. Configure a ratio factor for the current sensors when a current transducer (CT)
is used to measure the much higher level on the primary side at a substation or step-down
transformer that has a built-in metering current transformer.

Use the current ratio to increase the sensitivity of the iFlex sensor. Wrap the iFlex sensor
around the primary conductor, for example 2X, and enter a ratio factor of 0.5:1 to get correct
readings. The default value is 1:1.

Harmonics Calculation Method. Select the harmonic calculation method to apply according to
IEC 61000-4-7. The Analyzer applies a FFT (Fast Fourier Transformation) every 10/12 cycles
(typical 200 ms), that delivers spectral components (bins) every 5 Hz from dc up to ½ fs. The
‘fs’ is the sample frequency of the A/D converter, for example, 10.24 kHz. The standard allows
three different ways to calculate the harmonics from these 5 Hz components: Harmonic
Components, Harmonic Sub-Groups, and Harmonic Groups. See Ta b l e 8 .

Harmonic Components. The fundamental h01 and harmonics h02 … h50 are represented by

the bin of the harmonic frequency.

The interharmonics ih01 … ih50 are calculated from all spectral components between two
consecutive harmonic frequencies.

Examples:

 On a 60 Hz system, the h02 at 120 Hz is represented by the bin no. 24 (120 Hz / 5 Hz = 24).

 The harmonic h03 at 180 Hz is represented by the bin no. 36 (180 Hz / 5 Hz = 36).

 The interharmonic ih02 is represented by the bins no. 25 to 35 (125 Hz to 175 Hz).

Select Harmonic Components for measurements according to standards, such as IEEE 519,
that require the harmonics components measurement according to IEC 61000-4-7 or
IEC 61000-3-12.

Sub-Grouped Harmonics. The fundamental h01 and harmonics h02 … h50 are the RMS

average of the bin of the harmonic frequency and one adjacent bin to each side.

The interharmonics ih01 … ih50 are composed of the remaining seven bins for 50 Hz systems
or nine bins for 60 Hz systems between two adjacent harmonics.

Examples:

 On a 60 Hz system, the h02 at 120 Hz is represented by the bin no. 23, 24, and 25

(120 Hz / 5 Hz = 24).

 The harmonic h03 at 180 Hz is represented by the bin no. 35, 36, and 37

(180 Hz / 5 Hz = 36).

 The interharmonic ih02 is represented by the bins no. 26 – 34 (130 Hz…175 Hz).

Grouped Harmonics. The fundamental h01 and harmonics h02…h50 are the RMS average of
the bin of the harmonic frequency and half of the bins between two adjacent harmonic
frequencies to both sides. The center bin between two harmonic frequencies is included in
both harmonics with 50 %. Bins between h01 and h02 are not included.

Interharmonics are not available when the selection is grouped harmonics.

Examples:

 On a 60 Hz system, the harmonic h03 at 180 Hz is represented by the bins 31-35, 36, 37-41,

50 % of bin no. 30 and 50 % of bin no. 42

 The harmonic h04 at 240 Hz is represented by the bin no. 43-47, 48, 49-53, 50 % of bin no.

42 and 50 % of bin no. 54

The advantage of the measurements using grouped harmonics is to cover the entire spectrum
without the need to store memory-consuming interharmonics. Make sure to apply this
measurement only if the applicable standard requires this measurement method.

 Mains Signaling Voltage (MSV) frequency 1 and MSV frequency 2 in Hz

 Frequency range is 100 Hz up to 3000 Hz

 Limit

The voltage threshold limit value is defined as % of nominal voltage. The value is typically in
the range of 1 % to 5 %.

 Recording time

The event triggers a 10/12 cycle recording of up to 120 s.

Users Manual

Inrush Current. Inrush currents are surge currents that occur when a large or low-impedance
load comes on line. Normally the current will stabilize after some time when the load has
reached normal working condition. For example, the start-up current in induction motors can
be 10x the normal working current. See Tab l e 1 5 . The inrush current begins when the
½-cycle RMS current rises above the inrush threshold, and ends when the ½-cycle RMS
current is equal to or below the inrush threshold minus the hysteresis value. In the event table,
the extreme value is the highest ½-cycle RMS value of the event.
