1INTRODUCTION
1.1 Product Overview
The MINITRANS™(herein referred to as the product) is an on-line DGA (Dissolved Gas
Analysis) system for transformer diagnostics. The product measures the following key
fault gases in transformer oil: hydrogen, carbon monoxide and acetylene as well as
moisture in the oil and the transformer load current. Such data provides insight on
transformer condition criteria, such as developing faults, paper degradation and
electrical arcing. Once installed, operation is straightforward. All results are stored within
the product, but can be downloaded to a PC for analysis.
The key features and characteristics are summarised as follows:
Utilises dynamic headspace sampling to extract target gases from the oil sample.
No consumables, such as carrier gases are required.
Accurate results are available as often as once per hour.
Minimal maintenance*.
Uses highly accurate and stable Photo-acoustic Spectrographic technology.
Fully embedded microprocessor with non-volatile internal memory storage for
10,000 records.
Stainless steel outdoor-rated IP55 enclosure connected to the transformer by
robust stainless steel tubing.
All gas sensing is carried out internally –no external gas sensors.
Transformer load tracking is available.
One user-configurable relay contact based on absolute gas and moisture values.
Two sunlight-visible LED arrays on the exterior of the enclosure –one green for
power, one red for alarm.
Communication options include: Ethernet, RS-232, Cellular modem (GSM/GPRS),
PSTN modem, RS-485 and Fibre Optic. Other options may be available on request.
Internal USB connection provided for commissioning and service, or local data
download.
*Note: The only recommended maintenance is periodic cleaning of the air filters, in-line
oil filter and battery replacement.
1.2 Manual Scope
This guide outlines the use of the LCD display panel, manual DGA sampling function and
general maintenance activities.

Relay 2 notifies the user when a user-configurable caution and/or alarm threshold
is reached.
The red LED indicates a caution and/or alarm state. Flashing denotes a caution
state whereas continuous illumination denotes an alarm state. If after the next
measurement run, no alarm or caution states exist, the red LED switches off. Use
the TransConnect software to set alarm and caution limits for many different
combinations of results. (See the TransConnect user guide for more information).
5.3 Battery
The product uses a non-rechargeable lithium coin cell battery (Panasonic CR2450 3 V 620
mAh) as shown in Figure 5—3. In the event that the battery needs to be replaced, data
from the product must be backed up. Failure to do so may result in historical data loss.

7MANUAL OIL SAMPLING
7.1 Sampling Arrangement
The optional oil sampling port (if fitted) is located on the oil inlet on the base of the
product. This gives access to fresh oil via a manual sampling arrangement as shown in
Figure 7—1 to Figure 7—3.
Figure 7—1: Manual sampling arrangement
Figure 7—2: Product fitted with manual sampling arrangement
Figure 7—3: PTFE tubing
Before commencing work, ensure the use of suitable protective gloves, such as
nitrile rubber.
Perform the manual oil sampling according to the sampling process outlined in Figure 7—
4. GE recommends the use of a 50-ml ground glass syringe. Manual oil sampling shall be
performed while the product is in Standby mode –either wait until the product returns to
Standby mode or force the product to stop the current measurement cycle using the
TransConnect software. The optimum time to perform a manual sample is just after the
product has completed a measurement because fresh oil will be at the manual sampling
point.
Note: Collecting a manual sample while the product is performing a
measurement is not recommended as this could potentially affect the readings.

MA-006- MINITRANS User Guide - Rev 2.1 13-Oct-15 Page 19 of 25
7.2 Sampling Process
Observe the PRODUCT operating mode on the LCD display panel. Figure 7—4 outlines the
steps to obtain a manual oil sample.
Figure 7—4: Manual oil sampling process
1. If the product is in Standby mode,
proceed to step 3. If the product is
in Measurement mode, either wait
until the product returns to
Standby mode or use the
TransConnect software to stop the
active measurement cycle.
2. If an active measurement is
aborted, oil may remain in the
headspace. The display reads “OIL
DRAINING”. Wait several minutes for
the draining process to complete
and for the product to return to
Standby mode.
3. Once the product returns to
Standby mode, remove the plug
from the ¼ in. ball valve.
4. Take the PTFE tubing and connect
it to the ¼ in. ball valve (see Figure

8AIR FILTER CLEANING
The product draws air from the left-hand side and expels it on the right. The intake air is
filtered to remove the largest particles, so depending on environmental conditions the air
filter as shown in Figure 8—1 and may need occasional cleaning. The outlet filter may
also require attention.
Note: A higher temperature in zone two can be an indication that such action is
required.
Figure 8—1: Air filter assembly without cover
Figure 8—2: Air filter with cover
To clean the air filter:
1. First isolate the product through the external circuit breaker or external
switch.
2. To remove the cover, use a flat-head screwdriver or the supplied tab-pushing tool
to push the tab on the lower part of the fan cover as shown in Figure 8—1.
3. If a cable-tie is fitted to the filter holder, first carefully remove it. Remove the filter
holder by pulling off the black snap-off cover to the filter as shown in Figure 8—2.
4. If the filter mat is just dusty, clean it with dry compressed air or by beating it
against a hard clean surface.
5. If the filter mat is oily, clean it with mild detergent and water, and then dry it
thoroughly.
6. Replace the filter mat and snap the cover back in place. Note: The cable tie only
secures the filter holder during shipping so there is no requirement to replace.
7. Repeat for the other filter.
8. Re-energise the product and it will automatically begin measuring at the next
scheduled time.
