6 Internship Activities
6.1 RTU: Remote Terminal Unit
Since the theoretical world is diﬀerent than the real one, we realized there were a lot of undiscovered
things in the ﬁeld.
One such thing we were advised to research about by the employees was the RTU or the Remote
Terminal Unit. It is a computer based on micro-controller that is useful for interfacing a master-
system to controls of electrical equipment in remote locations. In the case of power systems, there
are diﬀerent levels, pressures and temperatures of oil inside a transformer, all these have to be kept at
certain levels for the transformer to work properly. There are sensors in the transformer to indicate if
any irregularity takes place. These sensors sense and send the data acquired to the master system in
the RTU. The RTU is connected also to the relays and switchgears that will work as per the command
from the RTU. The RTU locates in which transformer at which remote location did the irregularity
take place. Based on this, it commands that particular transformer’s control to switchgear or relay to
come into action and essentially turn oﬀ the said equipment.
6.2 TRM and QRM
Tri Ring Main or TRM is he kind of wiring/connection system in electrical power distribution system
in which there are two incomer components as inputs and one transformer as an output. In this system,
the placement of these 2 incomer/1 output transformer is in the conﬁguration of a ring. That is, a
circular conﬁguration. The combination is placed in the form of the ring at equal intervals and both
ends can be connected to incomer supplies.
The two incomer components are the input from the ADDC supply and it is still in the HV phase.
From these incomers it is stepped down and goes via the transformer to diﬀerent kinds of units and
now it is in the LV stage because this voltage will now be consumed by residential and/or commercial
A 2-incomer/1-output transformer combination can be added to this ring. In addition, if there is a
fault in a part where this combination is placed, the advantage of ring main is that the particular point
of fault can be isolated and maintenance can be done without problem as no interruptions would be
made except at the aﬀected point because the supply from both incomers is given to both ends of the
Quad ring main, this is the kind of conﬁguration of power distribution where there are as usual,
2 incomers as input components coming from the rot supply from government entities and for the
output, there are 2 transformers. This was also seen in the site visit.
6.3 Switchgears and relays
On the very ﬁrst day of our internship, we were given the concept of the use of switchgears and relays
in power distribution systems. Switchgears and relays are electrical components used to maximize
protection should any kind of fault or short circuit occur. Once a fault in a ring or a bus or any part
of the distribution grid occurs, the switchgears/relays come into play and trip or simply, switch oﬀ the
entire aﬀected part of the circuit so that the eﬀects of that particular fault do not act on the entire
Also, in transformers, when the parameters like the level, temperature and pressure are said to vary
greatly given their set values, the switchgears and relays come into action and trip the system.
Circuit breakers are also used as one of the protective components. The purpose of which is to prevent
the eﬀects of too many faults at one time. The basic job of the breaker is to interrupt the current ﬂow
when a fault occurs. Unlike fuses, that have to be changed every time a fault causes it to melt, circuit
breakers only have to be reset after the eﬀects of fault have been properly diminished.
The type of switchgears Sawa Lake employs in its operations on site are the the LUCY and PICOM
6.4 EasyPower 9.5
This was one of the most important activity. We were instructed by the General Manager eng. Hassan
Sheikhly to download and later on install this software called Easy Power in our laptops with acceptable
Easy Power is a software in which a variety of things can be done and analyses can be made, reports
be generated. It is a software that is similar to the one we had learned about in the theoretical studies
which was the DIgSILENT Power Factory. In easy power, however, the options are more visible,
user-friendly and the interface is also better.
In Easy Power, certain component that are usually used in the power systems and distribution have
their icons in the toolbox to the left of the screen in a column. These icons are of diﬀerent types of
circuit breakers, cables, transformers, buses to make busbars, relays and other protection devices.
Single Line Diagrams can be conveniently and easily made on this software. With every component,
double-clicking it will give the dialogue boxes to set the entire parameters related to that particular
component. For instance, double clicking the bus will give the dialogue box that lets us set the base
voltage and all the related things. Double-clicking the transformer will generate a dialogue box that
will let us set the parameters for the transformer like its MVA ratings and the winding ratio.
A typical single line diagram was made by us interns as per the case ﬁle given to us by the secretary
Ms Lynie Escober and the General Manager Engineer Hassan.
6.4.1 Short Circuit Analyses
The below given single line diagram was drawn by us upon a similar drawing made on a similar
software was given to us. The ﬁle that was given was basically of relay calculation and a part of it was
related to the single line diagram. That was the one that we drew. For the cables, parameters like
the cable length, the size have to be particularly set, for buses, the base voltage has to be set, for the
transformers the windings, the ratings and the impedance to be set for only when these parameters are
set according to the given speciﬁcations in the ﬁle given will the results be correct. This also means
that if the parameters are set close to the set value, the result will be as close to the accurate one.
Figure 2: The single line diagram that we drew on easy power
As you can see in the above picture screenshot, the toolbox to the left of the screen gives a complete
diagrammatic list of all the components used in the system. We used all of these to make a complplete
single line diagram as seen in the above ﬁgure.
We then used the Short circuit analysis as one of the analyses techniques given in the tab on top of the
software. This creates probable short circuit faults in each bus to see the eﬀects of it and then gives
us the data that like the short circuit current that may have resulted as a result of that short circuit.
After selecting that, we clicked on the icon that meant it would make a quick illustrative interpretation
of the short circuit.
Figure 3: The short circuit fault currents in the single line diagram that we drew on easy power
It was found from our results of this short circuit analyses that they were almost the same as the
results of the short circuit analyses of the given case ﬁle.
Easy Power also generated automatic reports for this short circuit analyses.
Figure 4: The LV momentary fault report table generated on Easy Power 9.5
Figure 5: The HV momentary fault report table generated on Easy Power 9.5
6.4.2 Relay settings, coordination and graphs
While working with the software and the same single line diagram, we were also to do the relay
coordination on Easy Power. Relay coordination required certain predeﬁned user settings that are
decided by users when the dialogue box is displayed. These settings are then entered there and we get
the results. Since we have 3 main buses with cables involved, we get the time coordination curve for
relay for these 3 buses.
Figure 6: The dialogue box for relay setting
Once we have made these, for every bus, we acquire the current time graph for each bus which has
normal Easy Power cables. Time coordinaton curve for the ﬁrst bus, thus, would be
Figure 7: the relay time coordination curve for bus 1
Relay coordination curve for the second bus:
Figure 8: the relay time coordination curve for the second bus
Relay coordination curve for the third bus:
Figure 9: the relay time coordination curve for the third bus
After we had done this, we generated reports for the relay coordination calculations on Easy Power.
Some of these coordination reports were as follows. The generated reports below are of the buses R-1
and R-3 in our single line diagram.
Figure 10: the TCC Coordination report for bus 1 R-1
Figure 11: the TCC Coordination report for bus 3 R-3
6.5 Site visit in the ﬁrst week
On the ﬁrst Saturday of the ﬁrst week, we were taken for a site visit. This site was the W-10 sector
located in the Khalidiya area of Abu Dhabi.
Engineer Naseer an employee at Sawa Lake who works as a general electrical engineer was the supervisor
on-site. The scope of work at W-10 was the changing the streetlights that were already there and
installing the new ones. Sawa Lake Electro Mechanical overlooked this operation in its entirety. Since
the day’s operation was in its concluding stages by the time we reached the site, we were able to learn
about the substation rooms and the feeder pillars
In one of the substation rooms located in the W-10 Khalidiyah area, like any other substation in an
urban locality, there was a compartment visible to the eye and an another compartment which was
behind it and it was inaccessible to the naked eye. In the one that is to the front and visible, there
are 2 transformers with the normal primary and secondary sides. The low voltage side, which is the
secondary side since this is a step-down transformer, has thicker wires because there is normal amount
of current coming with the a comparatively lesser force. The high voltage side has thinner wires. (We
related this to a water gushing example. If the same amount of water is coming with a greater force,
the pipeline is narrow and thin, if the same amount is coming with a lesser force, the pipeline is thick)
6.6 Second site visit in the second week
In the second week of our internship, we were taken to the site of Yas Retail mall. We went with Mr.
Kalam and other two workers. That day, they were to do the testing of the 22kV/0.4kV transformer
located at the site. This was a long and hard task as many parameters had to be properly and
accurately tested. Apart from that, the issue here was that an authorized person had the key and
access to open the transformer room and this took time as the person had not reached the place by
the time the Sawa Lake workers had reached.
Also, a complete summary of the ”Nameplate details” is acquired by simply looking at the nameplate
on the transformer and then recording it on the sheet of the Sawa Lake transformer test report.
The parameters involved in the calculation while the testing of the transformer is being performed
– Nameplate details
– Insulation resistance test
This test is carried out to ensure that the windings inside the transformer is properly insulated
without fail. Also, thermal deterioration is also checked for here.
This test is very important as it is key for commissioning and other stuﬀ. For this test, in the
winding category we have 3 divisions, which are the HV to earth, HV to LV and LV to earth. For
the forst one the standared voltage is 5kV, for HV to LV, the standard voltage is 2.5kV and for
the last one the voltage is 1kV.
For each of these standard voltage divisions, the resistance is checked ﬁrst at 15 seconds and then
at 60 seconds. The resistance values are recorded in the report.
Figure 17: site visit: The Insulation resistance test table
– Winding Resistance
This is the test where the resistance of the winding is tested. The taps are the ratios of the
windings internally set inside a transformer. These taps are set to certain combinations with
which the transformers are made to operate. These combinations could be as follows:
In the windings resistance test, for the High voltage side, for each of the tap combination, there
are 3 phases which are:
Therefore, the resistance for every phase in a single tap combination is checked using the multi-
meter OR the megger testing instrument. Once the values are acquired, these values are recorded
in the test report that was with Mr. Kalam doing all these tests.
On the LV side however, the tap is just one which is 03 and the diﬀerent phases are namely:
for each of these phases the resistance is checked for and is put in the report.
Figure 18: site visit: The winding resistance test table
– Turns Ratio Test
This test was done using a sophisticated hand-held megger device where a cable that is divided
in 2 is ﬁrst connected to the device and one end of it is connected to the LV side while the other
end is connected to the HV side. On either of these sides the connections of this cable is done
based on the phases that are color coded. The cables are connected to these color coded phases
with certain combinations.
These combinations for the HV phase connection are:
These combinations for the LV phase connections are:
The taps combinations of the transformer for the turns ratio test is the same as the previous one.
For every tap, there exist these 3 phase connection conﬁgurations for both, LV and HV. And thus,
for each of these phase combinations (in LV and HV), for each of the tap combinations, the turns
ratio is acquired through the sophisticated hand-held Megger device. The ratios are recorded in
Figure 19: site visit: The turns ratio test table
– Vector Group Test
The vector group conﬁguration and the such miscellaneous details are given in a way that can be
interpreted on the name plate:
∗ First letter in upper-case, in our case: D which implies Delta
∗ small letter denoting low voltage, in our case ”y”
∗ The angle of phase denoted by the hours in a clock
It is vital for the transformers to be connected in parallel in order for them to have the same phase
shift because if this is not the case, the transformer will inevitably act as a supplier of current
to the next one almost all the time. A typical transformer consists of primary and secondary
windings on the same core made of iron.

6.8 Cable testing machinery
On the Wednesday of the third week, the huge device that is used for cable testing purposes was
brought to the oﬃce as it was not being used and was not kept in the store. We were told by
Engineer Hassan, the General Manager, about the mechanism of the device and how it us used
also as a fault detector and how that detection is used to verify that the cable is doing ﬁne and
if its is not, then the requirement for a better and more usable cable is given.
Figure 26: The Cable testing device used by Sawa Lake for cable testing purposes
6.9 Streaming of security camera over the internet
A new set of security Closed-circuit TV Cameras had been installed and a task was given to us
which was to stream the view over the internet. Within the network it was used only as local
access but for it to be able to be viewed from outside as much as being in a diﬀerent company, it
had to be globally streamed.
The initial thing to be done was to acquire the Network system information from the digital
video recorder installed in the oﬃce of the general manager. The Local Area Network option is
available in many DVRs. This meant that we can access the stream from the local computers in
the company using the local IP address which goes like 192.168 so and so.
The issue arrived when the talk of accessing it from outside the network came as it wasn’t easy.
We did intense research on the subject and found that one way to access the security camera
stream from outside was to employ the method of port forwarding
Port forwarding is a method that permits pockets belonging to any protocol to be forwarded. The
local network had a global access from anywhere but the camera did not have it. Therefore port
forwarding was used to forward all the local ports of the local network to a pre-assigned global IP
address (that will represent the local address accessed from outside) such that when this global
IP address is entered in the browser with the speciﬁc port of the camera, the camera port will be
forwarded and the IP address of the local network will be accessed.
6.9.1 Things involved in port forwarding
∗ Port Map
∗ DMZ enabling/disabling
∗ rules to be made and applied
∗ starting port and ending port to be speciﬁed
∗ Protocol: either TCP or UDP or both at the same time
It was important to make the setting changes from the default settings so that the router could
be perfectly conﬁgured. There were many problems in this as sometimes a particular port was
not open. A few times even after all the port forwarding parameters were met, the camera IP
could not be accessed and some error was shown. Also, there were other issues faced like when
the streaming software app was downloaded on the iPad of the general manager, no stream was
After much trial and error methodology, the DMZ was ﬁnally enabled and port forwarding was
done and the camera could be accessed globally over the internet with the catch that it could be
done on Internet Explorer.
6.10 Third site visit
In the sixth week of the internship there was a site visit. This time the work was of maintenance
in the transformer. The site was near the roundabout of ADNEC. Since it was just maintenance,
not much was done as everything seemed proper and the transformer was not yet energized. It
was tested by one of the Sawa Lake employees back in August 2013.

7 Assessment of the internship
7.1 skills gained from the internship
The skills gained from the internship were positive to a substantial extent. From this internship,
we got to have valuable experience and this experience is the kind we will cherish for he rest of
Working on ﬁeld, observing the engineers gave us a hands-on training as to how we are supposed
to conduct ourselves while on duty.
It also taught us punctuality on site.
Another thing this internship taught us was the on-site rules and regulation that one has to follow
as an engineer. These rules are strict as they pertain to safety and security of life and property.
We were taught the importance of this as we were told to wear proper gears to work on-site like
the proper shoes and ﬂorescent jacket. Applying these gave us a real feel of what it is like to be
an engineer and to work on ﬁeld.
We also gained quite some technical knowledge in the oﬃce and as well as on site. We observed
the engineers who tested the transformers and had our queries and questions answered on-site. We
closely saw how all the tests were being done and what all equipment was used in these tests. The
special equipment used was vastly diﬀerent than what was used while in academics and theory.
This diﬀerence made us believe that other things will also be quite diﬀerent on ﬁeld than what we
learn in theory. This diﬀerence helped us to gain knowledge of how diﬀerent equipment works, for
instance, the megger make for testing, and how these equipment help us in getting the required
The knowledge of technical details of diﬀerent kind of equipment was acquired, also we got the
know how of the test document that the testing engineer has to ﬁll while testing. We saw the
diﬀerent ﬁelds in tables that were empty and had to be ﬁlled every time a test was done.
Another thing we learned was the way things are managed and handles in the company. Every
employee knows his and her proper job role and does all that he or she can to make sure that the
job is done in the right way. Coordination techniques and how we will have to work in sync in
the future was one thing of which the knowledge we acquired.
We also gained immense knowledge of the softwares that are used to generate, simulate and test
power systems and the most important of them was Easy Power. Knowledge of how to work with
easy power gave us command over it and we were able to design single line diagrams as per the
provided case ﬁles with signiﬁcant ease over time. Knowledge of Easy Power made us generate
reports with ease too. We were also able to carry out diﬀerent kind of tests and analyses including
short circuit, power stability and ﬂow, relay coordination. We could also interpret the diﬀerent
analyses result data and make conclusions based on it.
7.2 How will this internship eﬀect future career plans
This internship was really helpful in determining the road map for my future career plans. We
got to learn things that will pave way for advancing our career in the set ﬁeld. The site visits
were also very beneﬁcial for us as they taught us of the equipment that were used in the ﬁeld.
We had witnessed what it is to be working with competent people on ﬁeld and we also witnessed
the use of diﬀerent equipment and how they are stored in diﬀerent places. We also learned about
the coordination between diﬀerent people to carry out the task.
All this will prove to be helpful in our career and we already would have been exposed to diﬀerent
things put to use on ﬁeld.
7.3 How were internship activities diﬀerent from classroom knowledge
During our internship, we realized that what we saw in our internship time was quite diﬀerent
from what we have learned in the classroom.
On our very ﬁrst day when we were given the task to engage in general research about the Ring
Main Units and then to further it to Tri-Ring Main and Quad-Ring Main, we realized that these
were somethings we had not yet taken or even heard of while gaining theoretical knowledge in the
University. While the engagement in general research was going on, this realization was even more
as we found out that there were more vocabularies and abbreviations that we were not aware of.
These included the details of devices and systems like DMS and Remote Terminal Unit (RTU),
the details and information about which are mentioned in the Internship Activities part of the
There was also the aspect of usage of entirely diﬀerent verbs and vocabulary when describing
what competent people did while testing, maintaining and commissioning equipment at diﬀerent
sites. Vocabularies and usage of words in sentences like ”shutdown”, ”earthing” were a few of the
new usage learned. Apart from that, the whole business element og such electrical operations was
a somewhat new concept and how diﬀerent inquiries were received by the company and how the
company responded to those inquiries with a quotation based on a pre-decided price arrangement
was something we as students had seldom thought of
The vital relation between the skill of an engineer and the whole business element to it makes a
complete package and both go hand in hand. As students, we are taught of the theory in entirety
but when it comes to practical, hands-on training the monetary beneﬁts and losses pertaining to
an engineer’s skill is also equally important.
8 Conclusion and acknowledgement
To conclude, with this internship we take loads of needed experience and have a practical insight
