1. INTRODUCTION

Accurate knowledge of the condition of oil-filled equipment is of paramount importance to electrical
utilities. Dissolved Gas Analysis (DGA) has been essential in this area for many years, allowing faults
to be detected in their early stages, costly outages to be avoided and assets to be optimized.
The TRANSPORT X represents a new generation of test equipment for DGA in equipment oil, allowing
accurate, rapid, reliable results in the field. To ensure optimum performance of the TRANSPORT X it is
important to read this manual fully before using the equipment.

2. TECHNICAL SPECIFICATIONS

Table 1. Technical Specifications

* Accuracy is defined as accuracy of the gas analysis system and does not purport to define

gas-in-oil measurement accuracy which is affected by sampling and/or oil type.

3. SYSTEM DESCRIPTION

3.1 TRANSPORT X

The TRANSPORT X (see Figure 1) utilizes photo-acoustic spectroscopy (PAS) to perform extremely
high quality DGA analyses, giving measurements of all the fault gases plus moisture.
The gases extracted from the oil sample using a highly stable headspace equilibrium extraction
method are then measured using infrared photo-acoustic spectroscopy (a semiconductor sensor for
hydrogen). The TRANSPORT X can also test gas samples taken from a Buchholz relay (although with
reduced accuracy due to a very large dilution factor). The wide dynamic range of measurement of
the TRANSPORT X means it is also very suitable for testing tap-changer and circuit breaker oil.
The TRANSPORT X is contained within a rugged, impact-resistant, carrying case. Accessories for DGA
tests of oil are contained within a separate lightweight case. These include a sample bottle with
connections and pipes, and a syringe for extracting a 50-mL oil sample from the equipment and
injecting it directly into the bottle (see Section 3.2).
The TRANSPORT X contains an embedded PC and touch screen. The incorporated software contains
instructions to guide the user through the operation of the system and algorithms to assist the

TRANSPORT X Users Guide Page 5 Ver. 40-0157-04 03/07/2013

TRANSPORT X Users Guide

diagnosis of the electrical equipment. The PC has an internal database that can store over
16,000 records. Communication with external PC’s is possible via USB connections, allowing
databases to be downloaded to a laptop or desktop PC and then shared as required.

Figure 1. TRANSPORT X

A 2-inch thermal printer is provided, enabling the user to maintain hard copy records of all samples
tested on the instrument.
The power supply requirements are 115/230 Vac, 50/60 Hz.
A System Check Kit is available to allow the user to check the calibration accuracy of the
TRANSPORT X (see Section 8).
Optional extras are available for sampling of direct gas samples (see Section 7), and also for the
forced cooling of oil samples.

3.2 SAMPLE BOTTLE AND CONNECTORS

The sample bottle provided includes a “lid assembly” (see Figure 2) that incorporates airtight
compression fittings and a temperature probe incorporating a capacitance moisture sensor, all of

which are to be connected to the top panel of the TRANSPORT X. These gas connectors are of the
simple “snap-in” type but they are “polarized” so that only one order of connection of the input and
return is possible. Users must ensure that these connections are fully made when using the

TRANSPORT X.

Figure 2. Sample Bottle and Lid Assembly

It is recommended to analyze the sample as soon as possible after extraction, so that minimal
degradation of the oil sample occurs. However, GE Energy provides a ground glass syringe with the
TRANSPORT X that can be used for reliable sample storage for several days, provided it is kept out of
direct sunlight and extremes of temperature.
It is essential that the sample bottle be kept upright and not be inverted or placed in storage on its
side while containing oil to avoid ingress of oil into the pipe work. Dispose of the oil as soon as the
sample has been tested to minimize the risk of accidental pipe contamination (see Section 6).
Clean the bottle thoroughly after each test with a clean dry cloth or tissue (see Section 6).
It is important to ensure there is no residue of oil left in the oil injection port of the lid assembly or the
connections valve of the syringe, as this could cause contamination of the next sample to be tested.
Expel any oil trapped in these locations using a syringe filled with normal ambient air. This will ensure
that no unwanted residue of oil remains from a previous sample.
Care should also be taken to prevent any contamination from the syringe and thorough cleaning
should be performed after each analysis (see Sections 5 and 6).
Two Teflon-coated magnetic stirrers are provided; place one in the bottle before the lid is screwed on
during assembly of the pipe work. This magnet is rotated within the bottle during the analysis cycle,
and its presence is essential for the accurate operation of the TRANSPORT X. The magnetic stir bar
should also be wiped clean after each test. The stir bar can be removed from the oil in the bottle
using the retriever stick provided.
An in-line Teflon filter is fitted in both the return and inlet gas pipes. Luer lock fittings are used to
connect these filters. These fittings allow for quick replacement of the filters at regular intervals or if
oil should get into the pipe work by accident, thus blocking the filters. These filters are impervious to
oil at operating pressure and function to protect the instrument from oil aerosol, accidental spills and
airborne dust. Both these filters must be present at all times; if a spill occurs and oil makes its way
into the gas analysis chamber of the photo-acoustic module, the instrument will require a new
spectrometer.
It is recommended that the Teflon filters be changed after every 20 samples and the user will be
reminded to do this by the TRANSPORT X. If any oil residue is present in the pipes, or the filters

Figure 3. Accessories Kit

3.4 THERMAL PRINTER

The TRANSPORT X is equipped with an in-built 2-inch thermal printer that can provide hard copies of
results on-site. Changing the paper roll is very simple. Release the paper holder cover by depressing
the black catch on the left hand side of the holder (see Figure 4). To gain access to the paper roll
holder, lift the holder cover by its left hand edge, and swivel it on its right hand edge.
Place the new roll of paper over the roll holder and then lock back the paper holder cover in its
original position. The button on the top left corner allows the user to feed the paper through the
printer when fitting a new roll of paper, and also to check the function of the printer. Care must be
taken to ensure the thermo-sensitive side of the paper is orientated correctly during installation.

4. OPERATION

The TRANSPORT X has been designed to provide the user with a reliable device that is easy to use in
the field. The embedded PC and touch-screen display step-by-step user instructions, and there is also
an Instruction Card inserted in the lid of the case. A syringe and valves are supplied for oil sampling
and injection.

Note: Please read carefully and observe the following instructions.

 Read and follow the on-screen instructions carefully.
 Always use 50-mL samples of oil.
 Always use a clean syringe, lid assembly and bottle (see Sections 4.2 and 6).
 DO NOT use solvents to clean any of the apparatus or accessories.
 Place one magnetic stirrer piece in the bottle for the sample to be analyzed correctly.
 Following oil injection the sample bottle must not be moved until the analysis is complete. If the

bottle is moved the results will be adversely affected.

 When containing oil the sample bottle must be kept upright to avoid ingress of oil into the pipe

work of the lid assembly.

 Always ensure the pipes’ quick connect fittings are connected correctly and securely, as per

instructions.

 When removed, the bottle lid assembly should be held upright then cleaned carefully with a cloth

or tissue after use and before storage to avoid any ingress of oil into the pipe work (see
Section 6).

 Always empty the sample bottle waste oil after a test is completed. Also, clean the apparatus

after every test (see Section 6).

 The Purge time can be increased (maximum 10 minutes) to help prevent carry-over from a

heavily gassed sample to the next sample. 10 minutes should be used where available time
permits.

 Once the TRANSPORT X is unpacked from new, or after storage, the user should run a System

Flush operation to help clear the gas paths from potential contamination from any packing

material/gas effluents (see Section 4.2).

TRANSPORT X Users Guide Page 9 Ver. 40-0157-04 03/07/2013

TRANSPORT X Users Guide

4.1 TURNING ON/OFF

Where possible the instrument should be powered up 20 minutes prior to the first sample injection to
allow it to heat up. Oil sampling can be performed in this time if desired. The instrument can also
undergo a system flush during this period if desired.
The TRANSPORT X is powered by mains-supplied electricity or a suitable AC supply from a DC
inverter. To connect the unit to the mains supply, use the IEC cable supplied with the unit. With the
unit connected to the mains, switch the power On using the red power switch at the top right of the
front panel. The touch screen will then show the launch of the TRANSPORT X software (there will be
up to 20 seconds during which the software will boot) and the Main Menu screen (see Figure 5) will
be displayed.

Figure 5. Main Menu Screen

To turn the unit Off, press the Turn Off button found at the bottom left of the Main Menu (see
Figure 5). The system will then advise when it is ready to be switched off (see Figure 6). Use the red
power switch to switch off the mains supply.

Figure 6. “Safe to Switch off Power Supply” Screen

Similar to a PC, it is not recommended to turn off the unit directly from the power switch without
following the above shutdown procedure.

TRANSPORT X Users Guide Page 10 Ver. 40-0157-04 03/07/2013

TRANSPORT X Users Guide

4.2 PREVENTING CONTAMINATION

The TRANSPORT X is designed to prevent contamination between samples using only simple
cleaning techniques for the syringe, jar and lid assembly (see Section 6).
For best results:

 Clean the syringe thoroughly between each sample with a cloth or tissue (see Section 6).
 Clean the bottle and stirrer with a cloth or tissue.
 Clean the lid assembly pipes and probes with a cloth or tissue.

It is recommended that after first unpacking the unit and whenever time permits, the user should
implement a System Flush. This process flushes ambient air through the TRANSPORT X for
20 minutes, and will help clear any potential contamination from packing material/prior samples.
This function can also be used to clear the TRANSPORT X of gas after a concentrated gas-in-oil
sample e.g. LTC. Details regarding the use of this function are given at Section 4.3.5.2.

4.3 TRANSPORT X OPERATION

The instructions displayed on the touch screen are used to control the operation of the
TRANSPORT X. Upon powering-up the screen shows the Main Menu display (see Figure 5).
There are five options:

 Start New Measurement: see Section 4.3.1.
 View Previous Results: see Section 4.3.4.
 Turn Off: see Section 4.1.
 PC Sync: communicating with PC software – see manual.

button to proceed with the testing.

Figure 19. Bottle Installation Error Message

If the bottle temperature connection is in order, the Purging Time window (see Figure 20) is

displayed. The unit prepares for the oil sample by first “purging” with ambient air, and then by
automatically taking a zero reference measurement. The user selects the required Purging Time,
typically between 5 and 10 minutes. The default is 5 minutes, but longer purges can help eliminate
contamination from previous samples which were heavily gassed, for example from Tap Changer oil
samples.

Note: If 5 minutes is selected, the actual time is approximately 5 minutes and 40 seconds as this is a default minimum.
If 6 minutes is selected, the actual time 6 minutes.

Figure 21. Purging Progress Screen

When the purging is completed, the unit automatically calculates the gas concentrations in the air of
the TRANSPORT X / dry sample bottle combination in order to provide a zero reference for sample
measurements using the selected sample bottle. The Progress screen is shown in Figure 22.

Once the zero references have been calculated, the TRANSPORT X is ready for the oil sample to be

injected into the unit’s sample bottle.

4.3.1.3 Injecting Oil Samples Into the TRANSPORT X

Having obtained a representative oil sample (see Section 4), it is important that the sample be
handled correctly in order to ensure reliable results. Problems with sampling, storing or injecting the
oil sample can all affect eventual results.

Note: If a sample is not tested immediately after being taken, it is recommended to store it in a dark, cool place.

Follow the following procedural steps to inject the sampled oil into the TRANSPORT X sample bottle.
If the oil was hot when the sample was taken, shake the oil sample with a slight positive pressure on
the syringe plunger before submitting it to the TRANSPORT X for analysis. The reason for this advice
is that if the oil was hot when the sample was taken, it is possible for gas from the sample to come
out of solution and form a bubble as the oil cools. By shaking the sample with a slight positive
pressure on the syringe, the gas should be dissolved back into the oil and the sample should then be
ready for analysis.
Once the sample is confirmed to be correct, follow the on-screen instructions in the Gas Analysis
Instructions screen (see Figure 23) to inject the oil sample. These instructions are described in more
detail in the rest of this Section 4.3.1.3.

Only 90 seconds are available to complete the injection process. The Gas Analysis Instructions
screen displays a progress bar representing the run-down of these 90 seconds and the Time
remaining for sample injection is displayed on the screen. The TRANSPORT X also emits a beep
sound at 5-second intervals during the injection period.
If the sample injection is not completed in the 90-second injection period that is available, the

Sample Injection Timeout screen is displayed (see Figure 24). The user is then required to press the
OK button and return to the start of the injection process.

Prior to sample injection, the male quick-connect fitting should be attached to the syringe’s
three-way stopcock (see Figure 25).

Figure 25. Male Section of the Quick-Release Valve Connected to the Syringe

Connect the syringe to the sample bottle. The outer sleeve of the female fitting on the lid assembly
should be held between the thumb and the forefinger and pressed downwards as far as it will go (see
Figure 26). Insert the male quick-connect fitting that is attached to the syringe firmly into the female
connector. A slight click is heard when the connection is fully made. Release the outer sleeve of the
female connector to secure the connection.

Figure 26. Outer Sleeve of the Female Connector

Turn the three-way valve 90 degrees to open the arm from the syringe to the bottle, thus closing the
side arm of the valve (see Figure 27).

Figure 27. Stopcock (Three-Way Valve) With Side Arm Closed

Note: If the side arm of the valve is not closed, the oil will escape.

Slowly depress the plunger of the syringe fully. When the syringe is fully depressed, maintain gentle
downward pressure on the plunger, wait 3-4 seconds and disconnect the syringe at the quick­release valve. To do this, press down the sleeve of the female section and lift the syringe, three-way
valve and male quick-connect assembly away from the female section. Take care not to separate the
male quick-release section from the valve/syringe until the syringe is disconnected from the bottle at
the quick-release valve as that would provide an open channel for the gases to escape to
atmosphere.
Press the Next button on the Gas Analysis Instructions screen (Figure 23) to proceed with the
sample analysis.

4.3.1.4 Sample Analysis

Once the sample has been injected into the bottle, the temperature of the oil is measured. This is to
avoid condensation in the internal pipe-work of the system. Therefore it is recommended that “hot”

oil not be tested, and that it has time to cool. The important criterion is that the analysis cell is
warmer than the oil so it may be necessary to allow the unit to warm up if it has been stored in a cold
location prior to use. The temperature measurement takes 90 seconds.
If the oil temperature is higher than the internal cell temperature, then the sample analysis will not
continue. The screen will display this temperature difference and its countdown (see Figure 28). Do
not remove the bottle from the bottle holder cavity during this period. When the temperature
difference figure reaches 0.0 °C, the unit will automatically start the analysis, possibly with a delay
while the unit resets. Ensure the bottle is in place in the holder when the unit commences the
analysis.

Note: If the bottle is not in place at this time, the magnetic stirrer will not operate and therefore the results will not be
correct.

Figure 28. Temperature Countdown Screen

After the oil temperature measurement has been taken, the unit begins the process of measuring the
dissolved gases in the oil sample. Progress in making the measurements is shown by the display, in
succession, of the Direct Moisture Measurement Progress screen (see Figure 29) and the
Measuring Dissolved Gas Concentrations Progress screen (see Figure 30). The measurements take
approximately 22 minutes to complete.

Note: Do not touch or remove the bottle from the holder during the measurement process.

Figure 30. Measuring Dissolved Gas Concentrations Progress Screen

When the measurement procedure is complete, the results of the measurement are shown on the
Results screen (see Figure 31). It shows the concentration levels of the various dissolved gases and
the Total Dissolved Combustible Gas (TDCG) level that have been measured in the sample oil. The %
Relative Saturation (% RS) of the sample is also displayed if the Sample Oil Extraction Temperature
was entered into the TRANSPORT X’s diagnostic software (Figure 16).
