As the largest facility in the region our facility is capable of performing overhauling, rewinding, field services and life assessment studies on transformers ranging as well as offering a wide range of transformer re-engineering and field services.
Disposal of the failed unit is no longer your only option. Enduring lead times of one year or more for new units and solving the problem of different dimensions and termination locations is no longer necessary. alfanar technical services can provide the right solution for power/distribution/special transformers.
alfanar technical services has the distinction of being the first facility in the region to repair, rewind and commission a 200MVA transformer locally.
Power transformers are vital to ensure a trouble-free supply of power with no interruptions. Whether your transformer has failed or you are planning timely corrective maintenance our team of experts is available for short-term and long-term repairs.
alfanar Technical Services performs the repair, overhaul, and modernization of your power transformers that are performed in our dedicated repair shop. Our repair facilities handle to overcome all problems which arise during operational life cycles of the transformer including:
Our engineers work closely with local electrical contractors or in-house maintenance staff to design a program that meets your needs. We can rebuild your original transformer on site and in place if the situation demands.
At alfanar Technical Services (ATS), our Mission is to sustain our prominence as the provider of high-quality, precision-engineered repair and rewind services for Transformers upto 200MVA, 230kV. And to reinstate our commitment, we have commissioned the largest Vapor Phase Drying plant in the region, assuring higher and efficient quality and a much lesser delivery period.
VPD is used in drying of cellulosic insulation of the transformer winding which requires that the moisture content be brought to 5 ppm levels before impregnation of the winding with transformer oil, recovery of the oil and discarding the moisture. The fluid basically acts as a heat carrier to the insulation.
Advantages of Vapour Phase Drying Plant
Testing laboratory of ATS is well equipped to carry out following tests on transformers as per various standards like IEC , IEEE etc.
The Transformer test lab of alfanar technical services has been designed to perform all routine tests on transformers upto 200 MVA, 230kV class. The Laboratory is equipped with the most modern testing instruments.
Special and Type Tests
The site services provided by alfanar technical services, is an alternative to reduce the downtime and cost in the maintenance of the transformers. We mobilize a complete team of fully equipped experts to the sites to carry out the diagnostics, overhauling and repair of the transformers, without compromising on the Quality of service
We dry out moist transform at Site by various methods
alfanar Technical Services' experts provide you with a proper preventative maintenance program, to achieve an indefinite life to the cellulose. Our mobile unit allows expediting this process at your facility on live transformers, thus allowing close to zero downtime and high savings.
Regeneration of insulating oil is the process of removal of contaminants and products of degradation such as polar, acidic or colloidal material, as determined by oil and transformer tests.
With on-site regeneration and desludging, the oil is processed on site in the transformer tank. It is circulated from the bottom of the main tank, heated, and directed through 'structured clay columns', then filtered to particulate removal of 0.2 micron, vacuum treated and dehydrated before it is returned to the top of the unit via the conservator tank. The process is continued until the oil exceeds the specified minimum required levels. The method employs adsorption and thermo vacuum (dehydration and degassing) treatment in restoring the oil.
