Congratulations to your choice of FRAX Sweep Frequency Response Analyzer by Megger. We
at Megger have done our best and will continue do our best to satisfy our customers. Please
visit our home page at www.paxdiagnostics.com and do not hesitate to contact us directly.
Most dielectric and mechanical failures in large power transformers are preceded by
mechanical changes in the winding structure. These displacements in the winding structure
may be the result of transportation damage, short circuit forces, or natural aging effects on
the insulating structures used to support the windings. Detection of these displacements
before dielectric failure reduces maintenance costs, and improves system reliability.
FRAX Sweep Frequency Response Analyzer (SFRA) is designed to detect winding
displacements in power transformers or faults in the magnetic core. The system provides
attenuation signature curves that can easily be compared for deviations which indicate:
Core movements
Winding deformations and displacements
Faulty core grounds
Partial winding collapse
Hoop buckling
Broken or loosened clamping structures
Shorted turns and open windings
Unique features of FRAX:
High accuracy
Small size and low weight
Powerful analysis tools that are intuitive and easy to use
Wireless, Bluetooth, communication between laptop an instruments allows flexibility in the
field (FRAX-101 only)
Galvanic isolated USB interface for personnel and equipment safety

1.4 Bluetooth Communication (only FRAX-101)
Bluetooth is a standard for wireless serial communication. Simply speaking, Bluetooth
replaces a serial cable between your laptop and the FRAX instrument.
The output power of Bluetooth modules are divided into three classes:
The Bluetooth module used in FRAX-101 is class 1. Also, the Bluetooth USB Adapter that
comes as a standard accessory with FRAX is class 1. Using this adapter communicating with
FRAX, you will get class 1 communication.
FRAX
7
Many laptops of today has in-built Bluetooth capability, most common is class 2. Since the
Bluetooth module used in FRAX-101 has excellent receiving properties, a built-in Bluetooth
device may be suitable in many situations. However in field/substation environments
Bluetooth class 1 is recommended.
To configure a built-in Bluetooth device, please follow the manufacturers instruction. To
configure the Bluetooth USB Adapter that comes with the FRAX, install the included
Bluetooth software
Note,
it is reported that in some cases an activated built-in Bluetooth and using an external
USB Bluetooth Adapter can create some conflicts in Windows. If this happens, uninstall both
adapters and reinstall only the one you plan to use.
First time you communicate with FRAX via Bluetooth, you need to establish your Bluetooth
communication before attempting to connect the FRAX Software to the FRAX instrument.
The following steps show how to add a connection between the FRAX instrument and the
computer using the Anycom USB-250 Bluetooth USB Adapter. Please note that the procedure
is managed by your operating system directly. Thus, the procedure necessary on your
computer may differ from the following steps, and it should be regarded as an example.
Start the My Bluetooth Places application and click on "Add Bluetooth Device"
befo re
you insert the adapter into the USB-port.
8
FRAX User's Manual
Add the device called "PAX Diagnostics".
A pass code is needed. Enter the code "0000" (four zeroes) as the pass code.
Select the PAX Diagnostics device.
Make sure that it is registered as a serial connection.
FRAX
9
You can now connect to your FRAX unit from the FRAX software.
Observe that the procedure described above only needs to be done once. Next time you start
the computer simply insert the USB adapter using same USB port or use built-in Bluetooth.
Important! If you install the external USB dongle in a different USB port on your computer,
you may get a different serial COM port assigned to that USB port. Either connect to your
other USB port or change the COM port in the FRAX communication setting. Then start FRAX
software and press connect.
1.5 Built-in Battery Pack and Charger
As an option, FRAX-101 is delivered with a built-in battery pack and charger. The battery is of
Li-Ion type, 4.8Ah, 11.1V. The charger is powered from the standard AC/DC adapter that is
delivered with the instrument.
FRAX-101 automatically enters low power consumption mode when waiting for a
measurement and because a typical sweep takes approximately 1 minute, the battery lasts for
at least 3 hours of measuring or more than 12 hours idle.
Charging is performed automatically when the AC/DC adapter is connected. The FRAX-101
does not have to be turned on. To ensure long battery life, batteries will not be charged if the
battery charge is higher than 90% or if the temperature is above 40C. A complete charge
takes approximately 8 hours.

FRAX User's Manual
1.6 Sweep Frequency Response
The FRAX "Generator" (Gen.) generates a sinusoidal voltage at a selected frequency and
measures the input voltages, amplitude and phase, on two input channels "Reference" (Ref.)
and "Measure" (Meas.). The instrument stores "Amplitude" and "Phase" data for both
"Reference" channel and "Measure" channel as well as the ratio "Measure" divided by
"Reference". The values can be plotted and exported as Magnitude, Phase, Impedance,
Impedance-Phase, Admittance and more. The Custom models function make it possible to
calculate almost any parameter based on the measured/stored data.
FRAX uses the sine correlation technique. This means that the input voltages are multiplied by
a sine and a cosine, and then averaged over an integer multiple of the interval of time. The
sine, cosine and the voltage applied have exactly the same frequency. The sine correlation
technique is well known and is suitable for Sweep Frequency Response Analysis (SFRA)
measurements. Since the signals on the two input channels are treated the same way, the
phase resolution between these two channels is very high. The rejection of DC offset and
harmonics - referred to as the applied voltage - are in theory infinite. By increasing the
integration cycles, the rejection gradually improves.
The IF Bandwidth is commonly used as a parameter defining the bandwidth around the
applied signal analyzed. An IF bandwidth of 10% of active frequency is equivalent to 12
cycles of integration.
1.7 Calibration
The instrument is calibrated before leaving the factory. The recommended calibration interval
is one (1) year. The instrument can be calibrated by Megger or any calibration institute that
follows the calibration instruction given in Appendix A, Calibration Instructions.
1.8 Disposal
FRAX and its accessories are all manufactured after August 12, 2005. Megger is responsible for
the disposal of old FRAX units. The FRAX unit can be sent back to Megger for disposal at any
time at no additional charge.

2.1 Saftey First
FRAX is a Sweep Frequency Response Analyzer designed for measuring power transformers in
the field and at manufacturing sites.
Always follow local safety regulations.
Make certain that all personnel who work with FRAX instrument have been trained in its
use and that all applicable safety precautions are taken.
Always connect the instrument to protective earth/ground using the separate earth/ground
cable. The earth/ground cable should be the first connection made and the last removed.
12
FRAX User's Manual
Do not use any accessories that are not intended to use with the FRAX.
Refer all servicing to qualified personnel.
2.2 Preparatory Procedures
Always follow local safety regulations!
The transformer must be disconnected from the net, which means that any connection to
the transformer bushings including neutral(s) must be disconnected.
The transformer tank must be properly grounded.
If the transformer is equipped with a Load Tap Changer (LTC), the position of the LTC will
influence the FRA measurement. The recommendation is to put the LTC in the position to
include all tap windings in circuit ("Extreme Raise" position), and note that this LTC
position is used. If making measurements at several tap positions, make sure to note each
tap position.
If the transformer is equipped with a De-Energized Tap Changer (DETC), the position of the
DETC will influence the FRA measurement. The recommendation is to leave it at the
nominal tap position unless otherwise specified. Make sure to note the DETC position in the
Nameplate section of the software.
1. Connect the FRAX instrument to station earth/ground near the power transformer to be
measured using the separate earth/ground wire (at bottom of transformer if instrument is
operated beside the transformer, at another good connection to transformer at top of
transformer if instrument is used on top of transformer). The separate earth/ground wire
should be the first connection made and the last removed.
2. Connect the test lead BNC connectors to the FRAX instrument, Generator (yellow),
Reference (red) and Measure (black).
3. Connect the AC/DC Adapter to the FRAX and a power source that meets local safety
regulations
4. If not using Bluetooth communication, connect the USB cable to the FRAX and your
computer.

2.3 Start Up FRAX and Establish Communication
If using Bluetooth communication:
Establish Bluetooth communication, see also detailed description Bluetooth Wireless
Communication. Usually you will be assigned a serial port number, e.g. 8 that should be
used when FRAX establish connection. Note that FRAX Software remembers the last used
port.
If using USB communication:
connect the USB cable to the computer and to the FRAX.

2.5 Test Lead Connection
The new innovative FRAX clamp helps the user to connect and achieve repeatable test results
in the simplest way possible. It handles both round and flat connectors and is easy to attach
to any bushing. The firm grip allows heavy cables and accessories to be mounted near the
bushing without any risk of the clamp falling off. The new clamp offers all necessary
connectors (BNC, ground braid, cable strain relief) in one clamp. See Appendix E: FRAX cables
and clamps.
My Docum ents

Quick Start Tutorial
15
Make sure to follow local safety regulations! Local safety regulations most certainly prescribe
all bushing connections to be earthed/grounded when working on the transformer e.g.
connecting the FRAX test leads. The ground braid shall go from the top clamp the shortest
way to the bottom of the bushing. Good ground connection is essential.
Important! The test connection polarity is important since reversed polarity will produce
different results. The user has to establish a polarity convention. In this software it is assumed,
and recommended, that H1-H0 imply the red/yellow connectors (source and reference) is
connected to H1 and the black (measure) is connected to H0.
Connect FRAX test leads:
Make sure to remove paint and or rust from the nuts or bolts used on the flange for proper
measurement ground connections.
Connect the red and yellow (source and reference) to the clamp at the top of a bushing and
corresponding ground braid to the base of bushing. Make sure that the braid do not touch
any conducting part at top of bushing.
Connect the black (measure) lead to the clamp at the top of the other bushing and the
corresponding ground braid to the base of bushing. Make sure that the braid do not touch
any conducting part at top of bushing.
Following local safety regulations, remove possible ground connections from top of the
bushings.
Using an easy repeatable cable setup is crucial to ensure reliable FRA results.

FRAX User's Manual
2.6 Test System Verification
Test leads should be checked for continuity and integrity before use. The best means for
checking lead integrity and correct operation of the equipment is to perform the FRA selfcheck using a standard test object. This check is especially valuable for checking FRA test
equipment, since there is generally no intuitive way of knowing if the test equipment is
giving correct results when making field measurements.
Quick Start Tutorial
17
Here you can see the result of test measurements. Showing short circuit measurement (black)
1), open circuit measurement using FRAX-101 (green)2) and FTB-101 measurement (red).
1) A simple test to check the integrity of test leads is a short circuit test. Simply connect the
"Source"/"Reference" and "Measure" clip together and connect the respective measurement
earth/ground together. The result should be an almost straight line around 0 dB (black).
2) An open circuit measurement should in theory provide a 0-response, i.e. a minus infinity
dB-response. However, all measurement systems have internal noise and the test leads will
also add some response from open clips ends. Separate the "Source"/"Reference" clip from
the "Measure" clip. The clips itself will give some influence at highest frequencies, if you
disconnect the "Measure" coaxial cable from the FRAX unit you will see the noise in the
measurement system (green)
