Introduction & The Company
1. Introduction
As an Engineering student in Prince Mohammad bin Fahd University at the
Electrical Engineering Department, I am required to do summer training at a
company in the Kingdom of Saudi Arabia or abroad. The summer training
program is an eleven weeks training. I have taken my summer training in Saudi
Aramco Company working for Consulting Services Department/Electrical
Engineering Division from Jun 16 to Sept 5, 2012
In this period of training tried to gain field experience in the areas related to
the electrical engineering. Also, I tried to look for new technologies and tools
available in area of electrical engineering. I applied theoretical engineering skills
into real world engineering problems. In Addition, I learned how to deal with
engineering project and technical problem solving. I got familiar with
organizational skills, work ethics, teamwork skills, and time management in a
field environment.
2. The Company
Aramco was established in 1933. It was the Arabian American Oil Company
until 1988 it was owned by the government and became Saudi Arabian Oil
Company. Aramco kept growing to be the most valuable company in the world. It
manages over 100 oil and gas fields and produces 3.4 billion barrels annually.
Consulting Services Department (CSD) focuses on safety, research and
technology, standards optimization, capital programs support, and operation
support and Improvement. CSD consists of four divisions; Materials Engineering
and Corrosion Control Division, Mechanical Engineering Division, Rotating
Equipment and Civil Engineering Division and Electrical Systems Division (ESD).
ESD consists of three units, Electrical Equipment Unit (EEU), Power Systems
Unit (PSU), Direct-Current Systems and Cathodic Protection Systems Unit
(DCSU). ESD provides consultation in these four fields.

with power systems and substation equipment group. Odah introduced me to the
department and the electrical systems division and gave me orientation on the
safety at office and plants.
My plan with ESD included working with the eight specialties that the division
have. The specialties are Cables and lighting, substation equipment, motors and
generators, cathodic protection, UPS and DC systems, power system, design and
studies, and substation automation.
3. Activities and responsibilities
3.1 Al-Oalyan Workshop Visit
I went with Mr. Hussian from Electrical Equipment Unit, motors and
generators group, to inspect a submersible pump from Khursaniyah Gas Plant.
The pump was tripped due to a ground fault immediately after starting it. The
pump was inspected and found that the motor side was having sort of “burn” or
heat exposed to the majority of the winding. Signs of carbon and discoloration
were observed on the winding, aside from the stator but not the rotor.
Fig.1 (Pictures Motor and the burn on the winding)

PMU | Internship Report
Activities & Responsibilities
Khursaniyah Gas Plant found that:
1. No Failure of the seal – Mechanical or cable Seal – found
2. Bearing was found moving freely
3. Greasing was in good condition
4. Lubricant oil was found clean
5. Signs of carbons found around the winding of the motors
6. 2/3 windings were found in a bad condition - carbonized and insulation
damage
7. The shaft was intact
8. Discoloration was found on the stator segments along with the damaged
windings
9. The failure occurred on the motor from the pump side only
At the workshop we saw the motor and we inspected it to see what could
cause the ground fault. The burn can be seen clearly on the winding there was a
sensor but we were not sure of it, is it for temperature or for the flow. After the
inspection, we discussed the possibilities of causing the problem.

3.2 WESCOSA Visit:
As a part of our summer training program with CSD, we had a site visit to
WESCOSA in Dammam in July 26, 2012. The purpose of this visit is to be familiar
with electrical equipments, transformers and switchgears, and the process of
manufacturing them. During this visit we got a quick overview about WESCOSA.
We had a presentation about WESCOSA transformers that meet the
requirements of Aramco. It follows SAES-P-121 and 16-SAMSS-536,531,534,533
in Aramco standards. They produce three types of transformers, Pole-Mounted,
Power Transformers and Pad-Mounted Three-Phase Distribution Transformers.
Page 10 of 43
PMU | Internship Report
Activities & Responsibilities
First, the Pad Mounted Distribution Transformer is three phase, oil filled, and
serves underground distribution loads. Pad Mounted Transformers are available
in two constructions live front construction, or dead front construction. The
ratings of the transformer are From 45 – 1500 kVA. The high voltage taps are ±2-
2.5% from normal.
Fig.2a (Pad Mounted Transformer)
Second, the Pole Mounted Distribution Substation Transformer is designed
for continues operation and It cooled itself for tropical climates. Pole Mounted
Transformers are suitable for indoor and outdoor installation. The ratings of the
transformer are From 50 – 1500 kVA and the high voltage taps are ±2-2.5% from
normal.
Fig.2b (Pole Mounted Transformer)
Third, the Power Substation Transformers is used to provide electrical
services for distribution system. In power transformer, both primary and
secondary cables enter the transformer cable boxes from below. There are
different designs to meet both IEC and ANSI standards. The ratings of the
transformer are from 500 – 34500 kVA and the high voltage taps are ±2-2.5%
from normal

PMU | Internship Report
Activities & Responsibilities
Fig.2c (Power Transformer)
Process of transformer manufacturing:
The process of transformer manufacturing is done by several steps:
1. Winding
They wind three phase winding , one by one
The inner winding is the secondary, while the outer is the primary
At the secondary, after certain winding turns, they extract a voltage
tap
2. Shell Core
They mostly use steel core
They are made of laminated steel to reduce Eddy current losses in the
core
Then they set them inside the winding side by side
3. Bushings
They weld three bushings, each to the transformer tank , each
bushing is connected with a phase winding
4. Closing
They place the windings inside the tank
Each type of transformer has different tank shape
Also, they inject a nitrogen gas to protect the transformer from arc
flash
After that, they inject the oil into the transformer from an oil reservoir
Page 12 of 43
PMU | Internship Report
Activities & Responsibilities
5. Testing
They do a test for both high voltage transformers and medium voltage
transformers
They have two testing areas for each type
Some of the testing they do are :
o They test the open circuit and short circuit to measure the
losses in the core and the winding
o They do a high voltage test to inspect the insulation between
the winding turns
Switchgear manufacturing process:
In the factory of switchgear, we have started with how they do the cover box
and where they cut, band and insulate the cupper plates. Also, we have seen how
they connect the circuit breakers as well as the wiring. Finally, they explained to
us how the test of switchgears is done. In addition we saw different types of
switchgears with respect to voltage, which are low, medium and high voltage
switchgears. At the end of our visit we have seen the control panels. These
control panels are used in low voltage applications as the panels used at homes.

Note:
WESCOSA prevents taken pictures in inside the factory. However, I took some
picture from the outside; you can find it in Appendix A
Also, you can find the report of the visit in Appendix B

Activities & Responsibilities
3.3 Motors:
During my summer training program with CSD, I took courses on motors
with Mr. Al-Ali. Also, I worked with the motors and I had an overview of their
function, types, and motors that Aramco uses. The main function of motors is to
convert electrical energy to mechanical and produce torque.
The operation of motors is based on three main principles. First, when the
electric current passes through a conductor, magnetic field is produced around
it. So, if the wire is wound around iron rod, the magnetic field will strengthened
and the rod will be magnetized. And, the magnetic field becomes stronger as the
turns of coil increases. Second, the direction of the current flow through coils
determines the location of the poles on the electromagnetic. Third, like poles,
such as two north poles repel each other. Unlike poles attract each other. So, if a
bar magnet is suspended between the ends of a horseshoe magnet, the bar
magnet will rotate until its north pole is opposite the horseshoe magnet's South
Pole.
Fig.3a (Magnetic Theory)
There are two types of motor, DC motors and AC motors. DC motors are used
where high torque and controlled speed over a wide range are needed. It
requires high level of maintenance. AC motors are usually used in industrial
applications.
There are three types of DC motors classified according to the type of
winding; Series-wound, Shunt-wound, and Compound-wound motor. In Series-
wound motor armature and field coils are connected in series. In Shunt-Wound
armature and field coils are connected in parallel. The Compound-wound motor
incorporates both Series-wound and Shunt-wound windings.
Page 14 of 43
PMU | Internship Report
Activities & Responsibilities
The main two parts in typical DC motors are stator and rotor. Where stator is
the stationary part and rotor is the rotating portion of a DC motor. The stator
consists of the frame, filed winding, brush rigging, and brushes and end bells,
where the rotor is consists of the armature, commutator, and blower.
Fig.3b (Components of DC motor)
There are three type of three-phase AC motors; Squirrel-Cage Induction
Motor, Wound-Rotor Inductor Motor, and Synchronous Motor. Squirrel-cage
induction motor is the common of all AC motors and has the sample
construction.
The major components of squirrel-cage motor are; the stator, rotor, field coils,
and fan.
Fig.3c (Components of AC Squirrel-Cage Induction Motor)

Fig.3e (Three-Phase Motor Winding)
The other type of AC motor is synchronous motor and it operates at constant
speed. The major components for Synchronous motor are; Stator, Laminated
Salient Pole, Solid Salient Pole Rotor, and Cylindrical Rotor. Synchronous motor
has different starting method. A three-phase current is supplied to stator
winding to produce magnetic field and direct current is supplied to rotor
winding to produce magnetic field with fixed polarities at each end.

3.4 Wasit Project Review:
I joined Mr. Abdulmohsun form PSU in reviewing the Wasit Cogeneration &
Steam Generation project on ETAP. Wasit Cogeneration & Steam Generation
consists of six generators. Four Combustion Gas Turbine Generators (CGTG),
each rated 148.954MW at 16.5kV. And, two Steam Turbine Generators (STG),
each rated 75MW at 13.8kV. The purpose of the electrical system studies is to
verify the design of the electrical system:
Main Equipment (generators, transformers, switchgear) sizes, ratings and
main parameters
Starting of largest motors
The review includes three parts load flow studies, short circuit studies, and
motor starting studies. For the load flow analysis we did three cases maximum
system voltage, normal system voltage, and minimum systems voltage. In all
cases we shall check the voltage level. For low voltage, the level shall be between
95-105% and for high voltage the level shall be between 97-105%
For the maximum case, it shall be feeding form two sides, all motor
disconnected, and the bus-tie breaker is open. For the normal case, it shall be
feeding from two sides, all loads are running, and the bus-tie breaker is normally
open. For the minimum case, it shall be feeding from one side, the bus-tie
breaker is close, and all loads are running.
For the short circuit analysis we shall assume the pre-fault to 102%. It shall
be feeding from one side and the bus-tie breaker is close. We shall fault all buses.
For the motor starting analysis, the minimum voltage level for the motor
terminal shall be not less than 85%. If utilization equipment modeled as lumped
Page 17 of 43

Activities & Responsibilities
load at distribution bus, minimum voltage shall be not below 90%. We shall
check the largest motor in the system at starting.
There was a problem with the transformer voltage level and Mr. Konash
sends to them an email about it.

4. Major tasks or projects
1.1 Meeting with Facilities Planning Department (FPD)
I joined a meeting with Mr. Abdulmohsun from Power System Unit (PSU) and
FPD. It was regarding a voltage drop caused by starting a large motor in Tanajeeb
The FPD brought three suggestions they want to discuss and review on ETAP:
1. Adjustable Frequency Drive (AFD)
2. Transfer the loads, which are affected by starting the motor, to another
bus
3. Static Var Compensator (SVC)
The Adjustable Frequency Drive (AFD) was the last choice that may use
because the cost of AFD is very high. Transfer the loads to another bus will not do
much change for the motor to start. But, it will improve the operation of the loads
as the motor start. Static Var Compensator (SVC) will improve the operation so
the motor can start by providing VAR reactive power. However, using the SVC
with loads are connected to the same bus of motor will be a problem to the
operation level of loads as the motor start (it will be less than 90%, NOT OK!).
However, the decision has not been taken yet.

1.2 Repairing Motor in Melssa Workshop:
I went to Melssa workshop with Mr. Al-Ali to inspect a motor. Then I attended
meeting in Melssa workshop to evaluate maintenance that the motor need. The
meeting was between Melssa, CSD, and MSSD. CSD motor specialist support is
required finding and evaluating the looseness of the Stator supports, Rotor pole
plat looseness, and Bearing housing tight on the bearing.
We have discussed during the meeting:
- The looseness of the Stator supports.
For the fingerplates, we need to apply the epoxy to fix the fingerplates. A
good indication, we have noticed in the fingerplates is that they are not

broken so there should not be a major concern with fixing these
fingerplates with epoxy.
- Rotor pole plat looseness -which needs farther inspection as recommended
by CSD and MSSD QA to determine if need to install a new rotor kit.
The contractor should inspect the poles by removing the cover in order
to verify the cause of looseness and also the thickness of the cover should
be measured to verify if it meeting the original design thickness
- Bearing housing tight on the bearing – two options repair plan either to
machine

Conclusion
2. Conclusion
In this period of training I had a good chance to get field experience in the
areas related to Electrical Engineering. I opened my mind to new technologies
and tools available in industry. I had a chance to use my theoretical engineering
skills gained in academia into real engineering problems. Also, getting involved
in engineering project and technical problem solving helped me to use critical
thinking and teamwork strategies. Visiting factories and workshops helped me to
be familiar with the electrical equipments and the process of manufacturing.
Also, I had the chance to work with specialties and engineers and benefit from
their experiences.
