What is thermography?

Thermography is an efficient preventive and predictive maintenance-be it mechanical or electrical. Thermography is the time- and cost-saving method for non-contact detection and analysis of thermal anomalies during maintenance


How thermography services way out for easy solution?

There was a time when maintaining & detecting problem areas in big production plants or industries & utilities was a tough job. However, the thermography or thermal imaging technique has revolutionized the complete predictive maintenance inspection cycle for all types of industries.

The commonly faced problems by most manufacturing industries & utilities are electrical fires & production downtime, something these industries just can’t afford. Thermography comes up as an effective solution for all such industries.

Thermal imaging cameras help in the quick & accurate scanning of the entire surface of an electrical equipment or machinery to visualize the temperature differences in the form of thermal images. In manufacturing industries, thermography helps the maintenance experts in detecting problem areas & hot spots for preventing production downtime & major electrical fires. It can be applied to a wide range of electrical & mechanical equipment for detecting temperature anomalies, leakages, overheating, overloading, etc.

Thermography in utilities helps detect problems during power generation, distribution & transmission.

Infrared thermal imaging can not only be applied to the manufacturing industries & utilities, but also to facilities like hospitals, hotels & offices. It helps electrical contractors in scanning electrical connections & cabinets, that too in a non-contact mode that allows scanning objects for temperature differences without getting into danger.

Owing to this widespread application of thermography, it has contributed in a big way to substantial cost savings.

  • Manufacturing Companies
  • Electrical Contractors

What are the Advantages of Thermography?
  • You get a visual picture.
  • So that you can compare temperatures over a large area.
  • It is real time capable of catching moving targets.
  • Able to find deteriorating components prior to failure.
  • Measurement in areas inaccessible or hazardous.

Benefits change to Benefits of Thermography?
  • Reduction of production losses due to unplanned.
  • Reduced maintenance and repair costs.
  • Increased equipment life.
  • Increased Mean-Time-Between-Failures (MTBF).
  • Increased productivity and profitability.
  • Reduced insurance premiums.

Various Thermography applications:
  • Condition monitoring.
  • Medical imaging.
  • Research.
  • Process control.
  • Nondestructive testing.

While Transformer is in operation, transformer oil is subjected to electrical, thermal and mechanical stresses. In addition there are contaminations caused due to chemical interactions with windings and other solid insulations, catalyzed by high operating temperature. As a result, the original chemical properties of transformer oil changes gradually, rendering it ineffective for its intended purpose after many years. Hence this oil has to be tested periodically to ascertain its basic electrical properties, and make sure it is suitable for further use or necessary actions like filtration/ regeneration has to be done.


NABL Accredited Transformer Oil Testing Laboratory in India -

National Accreditation Board for Testing and Calibration Laboratories (NABL) is an autonomous body under the aegis of Department of Science & Technology, Government of India, and is registered under the Societies Act 1860. NABL has been established with the objective to provide Government, Industry Associations and Industry in general with a scheme for third-party assessment of the quality and technical competence of testing and calibration laboratories. Government of India has authorized NABL as the accreditation body for Testing and Calibration Laboratories.

Recommended to perform routine tests at least once a year in order to monitor the healthiness of your transformers. Faults can occur at any stage of transformer’s life and evolve rapidly. Testing your transformers on a regular basis will allow you to detect any unforeseen change in the condition of your transformers. Transformer oil purification is a process to remove sludge, dissolved moisture and dissolved gases from the oil. Transformer oil conditioning may also include to some extent improving the acidity of the oil.

 

A good oil purification system is able to deliver filtered oil with parameters as per the standard specification.

 

However, this revival of the oil by oil filtration plant to standard oil parameters is based on the quality of unprocessed oil and its initial process. In case the unprocessed oil does not match the standard oil parameters, then the effort of transformer oil filtration is all in vain. Alternate method of regeneration of transformer oil should be adopted in this case.

 

Transformer oil filtration by vacuum type dehydration and centrifuge type removal of solids and water separation.

 

Transformer oil conditioning is a stream line oil filtration process of sludge purification, moisture removal and gas removal.


The first step in the transformer oil purification:

The first step in this serial process is to raise the oil temperature to a desired level, generally upto 65 Deg C. This aids to give the oil latent heat which later aids to dissociate the moisture and gases from oil in the degassing chamber. Additionally the viscosity of the oil drops which aids in better filtration to some extent. Recommended heater design should consider an area of heating of about 1 to 2 W/sq.cm. In the transformer oil purification plant, the heating system is protected against over pressure built up and excess temperature rise.


Second step of transformer oil purification:

 

The second step of transformer oil purification plant is removal of sludge and dirt from the transformer oil.


Two methods have been used for removal of the sludge:

Removal of sludge by filter candles. and/or Removal of sludge by centrifuging action.
Oil Filtration And Circulation (Min 3 Cycle) Cycle As Per IS:1866:2000.
Field testing of Dielectric strength (BDV) of the Transformer Oil should be carried out in accordance with the provisions of IS 6792 & IS 1866 at regular interval during filtration job. The readings must be submitted to EIC for acceptance before stopping the filtration job.

The BDV test shall only be conducted after giving sufficient time for the oil to settle down after stoppage of the filtration process. Min BDV Value after completion of filtration and cooling down of oil should be min 60KV using 2.5mm gap electrode as per IS 6792 & PPM should be less than 20.

Removal of all suspended particles such as dust, rust, scales, colloidal carbon oxidation sludge etc. up to < 1 micron. Degassing and Dehumidification of Transformer Oil under vacuum. Circulation of heated Oil and Filling of treated oil in Transformer tank. De-acidification by evaporation and adsorption method.

 

Our single stage plants are capable of attaining following oil parameters in 3-4 passes and Two Stage Plants in 1-2 passes.


Oil Transfer & Circulating System: Mainly consists of inlet pump (Gear type positive displacement), Outlet pump (positive displacement Gear type or Multistage Centrifugal) and necessary valves & piping to ensure easy operation and maintenance. Complete system is vacuum tight to have a leak -proof operation.

Benefits Of The Annual Maintenance Contract (Amc) :

In today’s competitive era, quality is a prime factor. The quality output from any Transformer depends on Transformer's repeat performance. To get repeat performance; Transformer maintenance is a key factor. Maintenance of Transformers with requires special skills. Every organization may not have specialized maintenance team to take care of all variety of Transformers. Special engineers are the best people to support in maintaining these Transformers as total technology is available with them. In order to help our customers in getting the best throughput from the Transformer, we have introduced the concept of Annual Maintenance Contracts for the Transformer up to 100 MVA.

 

The Annual Maintenance Contract is the legal agreement normally conducted between two companies wherein the later agrees to render the maintenance service annually to the former at an exchange of the nominal amount. It ensures that the later promises to provide maintenance services to the former all throughout the year on a regular basis.


Annual Maintainance Contract: (Amc)
  • Transformers Annual Maintenance Contract
  • AMC for Erection, Testing, and Commissioning of Transformer
  • AMC for Supervision of Transformers in your plant
  • AMC for Health Monitoring of your Transformers
