Importance of Maintenance to Increase
a Transformers Life Miracle Electronics
Today, many companies are adjusting their costs
and expenses, and are changing internal policies
that help in reducing maintenance tasks and
operations in electrical equipment. This
obviously brings minimized costs, but only for a
short period of time. In fact, this also results
in increased risks in the long term because less
maintenance means amplified threats. Also, such
modifications and reductions result in making
such transformers work above their normal
load to get the expected performance. And,
ultimately this results in making it difficult to
obtain maximum profit from their normal work.
Therefore, reduction in maintenance operations
results in negative impacts like lack of
efficiency and premature ageing.
Because of all the above reasons and more, it is
advisable that a minimum preventive maintenance
program is carried out to detect risky situations
so that defined corrective actions can be
undertaken. Such maintenance programs when taken
up can avoid mid-term breakdowns, electric
failures, and non-programmed stops ultimately
avoiding inconveniences in the end customers
service. A preventive maintenance schedule
comprises of regular inspections and component
replacements as per the product maintenance
schedule. The organic products within
transformers degrade over time and ultimately
lose the capability to

• withstand stresses that they might see in their
  daily usage, like vibration, short circuits,
  energizing, etc. All of these stresses and faults
  must be detected as soon as possible to avoid
  further damage and repairing costs.
• In order to choose the most appropriate
  maintenance program, you first need to know the
  status and evolution of the transformer. Also,
  you must make sure to purchase your transformer
  from a manufacturer that utilizes the best
  quality raw materials, and standard procedures
  to construct its transformers. One such name you
  can rely upon is Miracle Electronics who
  manufactures power transformers in India that are
  RoHS Compliant, Reach Compliant, and available
  with CE and UL marks. Other elements that need to
  be considered for faults include transformer
  accessories like isolators, oil cooling pumps,
  and tap changers.
• The most important efforts acting on a power
  transformer include mechanical efforts, thermal
  efforts, and dielectric efforts. Similarly, there
  is various diagnosis techniques used for
  analyzing power transformer faults. These
  include
• Mechanical analysis excitation current,
  capacitance, short-circuit impedance, polarity,
  transformer ratio, frequency response analysis,
  and winding resistance.
• Thermal analysis infrared thermographs,
  dissolved gas chromatography, hydrogen
  equivalence method, and furanics analysis.
• Dielectric analysis dielectric rigidity,
  humidity, isolation resistance, capacity,
  dielectric frequency response, and ultrasonic
  method.
• Today, it is even more important than ever before
  to use high qualification measurement equipment
  that allows making the tests as automatic as
  possible and having a data base to optimize
  diagnosis tasks, due to the reduced stop times
  available. As transformer manufacturers, it is
  important to carry out tests that are under
  applicable norms to ensure that the transformer
  will work perfectly under every environmental
  condition.
• To sum it all up, we can say that it is really
  important to make preventive maintenance plans to
  keep active the optimal service conditions, and
  foresee faults to avoid unexpected high costs.
