This document is a student's final report on testing the earthing system of a 10 MVA power transformer at a substation in Palembang, Indonesia. The student defines a final report and the purpose of their report. The background discusses how electricity usage is increasing with technology, requiring reliable distribution systems. Earthing systems are important for protecting equipment from short circuits and leakage currents. The objectives are to determine the electrode type used and grounding impedance. Benefits include preventing disturbances, maintaining power distribution, and protecting workers from electrical shock. The student thanks the reader for their attention.

1. EARTHING SYSTEM POWER
TRANSFORMER 10 MVA IN SUBSTATION

2. Definition of the Final Report
 Final report is academic activities carried out by
each student before ending his study in the
application of knowledge and skills acquired in
the form of scientific papers.
 Scientific works prepared by students as
evidence of academic ability / professional
students concerned in applying theory learned in
college to address or solve practical problems in
industry / field according to the study.

3. Background
At the time of the current global era, the more rapid
development of technology and the use of growing
advanced equipment, so need for electrical energy
consumption also, in its own use of electricity is an
important role in human survival, so the use of above
requirements can not be stopped and the electricity
needed any time by the consumer.
In its use which no limit, electricity can not be forever
distributed smoothly, because of several factors which
can affect the performance of the equipment being used
as a channel of electricity to consumers, one of them is
on the transformer and disruption which may happens
could be a short circuit or leakage current, resulting in
system needed to overcome or minimize the disruption

4. Background
Earthing system is very important to secure the
disruptions happen to such an electric short circuit on the
transformer and substation equipment on Seduduk Putih
Substation, with the grounding system in the substation is
expected to reduce or negate the leakage current in the event
of disruption in the distribution system, so that the
equipment that uses electricity can be protected from
damage caused by electrical interference.
To get good results earthing system, it would be
required an electrode, because the electrode may affect the
effectiveness of conducting a short circuit or leakage current,
so that the equipment will be more secure than the
disturbances that can happened to electrical.
So, it is necessary a safety function to avoid interference
and protection for electrical equipment as well as in humans,
one of them with the equipment connected to the grounding
system.

5. OBJECTIVES
The goals to be reached in the preparation of this
Final Report as follows:
1. Can be determine the type of electrode used.
2. Can be determine the magnitude of prisoners
grounding / earthing impedance of the ground
electrode.
The purpose of writing the final report itself in the
lectures is to qualify for graduation Diploma
education at Polytechnic Of Sriwijaya

6. BENEFITS
 Benefits to a Company (PT. PLN Persero)
1. Can be prevent disturbance and maintain the
continuity of power distribution.
2. Can be protect workers from electrical shock or touch
voltage.

7. Because I think the grounding problem is
very important for the security system in
electrical appliance, especially on the tools
or electrical machine that have high voltage
and current, so the accident factor is very
high, therefore it is also necessary to reduce
the high safety factors of work accident,
because within the guidelines of electricity,
safety is very important in a company.
