A power transformer is the most costly and essential equipment of an electrical transformer. So for getting high performance and long functional life of the transformer, it is desired to perform various maintenance activities. Not only that, but a power transformer also requires various maintenance actions including measurement and testing of different parameters of the transformer. There are mainly two types of maintenance of transformer. We perform one group is in a routine basis, and the second group is as when required.

That means for getting smooth performance from a transformer we have to perform some maintenance actions on regular basis. Some other types of maintenance of transformer we perform as when they are required. But if one performs regular maintenance properly, he may not have any provision of performing emergency maintenance. The regular checking and maintenance of the transformer are also known as condition maintenance.

Hence by proper condition maintenance, one can avoid emergency and breakdown maintenance. That is why one technical personnel should mainly concentrate on-condition maintenance. As 100% condition maintenance causes 0% breakdown of equipment. There are many different maintenance actions, to be performed on a power transformer. Some of them are on a yearly basis, some of them are on a monthly basis, some others are quarterly, some are on a half-yearly basis. These are mainly transformer maintenance actions, which are to be performed in 3 to 4 years intervals.

Scope of Works for Transformer maintenance and service are :

  • Transformer turn ratio (TTR)
  • Winding resistant measurement
  • Insulation test measurement
  • Polarization index (IP) test
  • Visual inspection of electrical dan mechanical system
  • Function test for fan dan control system

Jasa Pengukuran Tan Delta

Setiap peralatan listrik yang beroperasi pastilah mengalami stres terhadap faktor tegangan operasi, vibrasi, temperatur, kotoran dan lain sebagainya. Semua faktor tersebut akan menyebabkan penurunan ketahanan isolasi peralatan listrik secara terus menerus. Untuk mengetahui kondisi ketahanan isolasi tersebut perlu dilakukan jasa pengukuran tan delta

Dalam sebuah jaringan sistim tenaga listrik yang komplek, penurunan atau penuaan tahanan isolasi peralatan listrik merupakan suatu masalah serius yang dapat menimbulkan kerugian yang besar seperti kerusakan transformator, meledaknya Circuit Breaker dll.
Untuk menghindari breakdown peralatan yang tidak terduga dan kestabilan distribusi power sangatlah penting untuk mengetahui kondisi isolasi peraltan tersebut dan memonitor secra berkala untuk mendapatkan degradasi ketahanan isolasi.

Dalam sistim kelistrikan, Disipasi Fakor atau Pengukuran Tan Delta bertujuan untuk mengetahui kualitas isolasi suatu peralatan listrik. Oleh karena itu, suatu peralatan listrik yang baru perlu diketahui hasil uji tangen delta-nya yang nantinya berguna sebagai referensi untuk pengukuran tangen delta berikutnya yang dilakukan secara berkala, sehingga didapat grafik degradasi tahanan isolasi peralatan tersbut. Grafik hasil uji tanden delta tersebut akan memperlihatkan efek penuaan tahahanan isolasi suatu peralatan  mulai dari awal pembuatan sampai selama pengoperasian. Dengan data ini, dapat ditentukan kapan dilakukan pemeliharaan, penggantian peralatan tersebut secara terencana, sehingga kerusakan secara tidak terduga dapat ditekan. Hal inipun menjamin keamanan dan kestabilan supplay listrik.

Dengan kebutuhan tersebut di atas, kami memberikan jasa pengukuran tan delta baik peralatan berdasa kecil atau generator dengan daya 45 MW ke atas.

Pada pengukuran Tan Delta tersebut, kami mengguakan Omicron CPC 100 TD dan juga menggunakan Megger Delta 4000 series.

Balancing Service

Balancing Service is a procedure to check and adjust rotor mass distribution to ensure the vibration level or bearing force at frequency that matches the speed within the specified limit.

Unbalance is defined as the imbalance of the distribution of mass towards the centerline of rotor. This imbalance will cause the bearings to accept additional centrifugal force that will impact the lifetime of bearing and catastrophic damage of equipment

Balancing Service


Empirically more than 50% of failures of rotating equipment are directly related to misalignment and unbalance due to higher vibration level which significantly reduces the wear life of the bearings, seals, shafts, and joints. Therefore, Precision Balancing can reduce vibration and operational costs and at the end availability and reliability of equipment will be improved

PT GAMMA ENERGI PRATAMA is able to provide on-site balancing service for many machines and applications in the Industry. We do field balancing by using a well-known brand of balancing machine or using portable balancing equipment and making in-situ corrections to the rotor. We can balance machines includes; turbine, generator, pump, motor, etc.

For more information and inquiry, please contact us at or call 081513166131

Static Balance
A state of balance existing in a rotating body when there is the coincidence between its center of mass and its axis of rotation so that the body is in neutral equilibrium under the action of standing forces.

Dynamic Balance
A state of balance of a rotating body wherein its weight (mass) is so distributed about the axis of rotation that there will be no tendency to displace the axis of rotation when running.

In-Place, Two-Plane Balancing

Cross effect must be taken into consideration when balancing in two planes. In the past, it has been very difficult to perform a precision two-plane balance in the field. Overhung rotors are the most difficult. With our vast experience and the technology of our vibration software and hardware, in-place two-plane balancing has become routine.

Field Balancing

Blowers or fans (unlike electric motors, pumps or compressors) often run smoothly only for a limited period of time or in a specific operating condition. Unbalances may occur during operation, causing costly damage to machines, foundations or buildings. However, in most conditions, dismantling the part for balancing is not a suitable option, because of high cost.

In such cases, field balancing is the best solution and PT GAMMA ENERGI PRATAMA provide Field Balancing of industrial rotating equipment. Precision Field Balancing minimizes vibration and its effect on bearings, shafts and seals. Precision balancing reduces maintenance costs and increases the life of rotating equipment. Our ability to perform precision balancing in the field saves our clients the downtime, labor and cost of removing the rotor and shipping it to a balancing shop.

Infrared Thermography

Infrared thermography can identify hot spots caused by defects in joints and components. infrared thermography (Jasa inspeksi thermography) is used to find excess heat in certain areas or components so that failure/damage to components can be avoided and creates insecurity when operating equipment or machinery and causes loss of productivity. Infrared thermography is the best diagnostic method for finding hot spots in the early stages of degeneration.

As a mechanical and electrical component, it certainly has the potential to become worn or damaged. By doing a Thermography the conditions in which the component or material experiencing signs of damage such as cracks, holes and others can be directly detected
Infrared Thermography can also find leaks in pipes or connections used in the industrial world. If infrared testing is carried out regularly, industry players can analyze the risk of errors that can occur. This condition is certainly very important for management to maximize production and give benefits to investors.
