Typically, the bis approved transformer manufacturers in India use the recommended, Statistical Quality Control or also known as SQC methods as far as possible. This SQC could be used by bis approved transformer manufacturers in Karnataka in order to maintain control over the quality of the product during its production.
The bis approved transformer manufacturers in Maharashtra generally maintain copies of any records or connected papers which could be required further by BIS. In fact, these documents are required to be made available at any time on request by the auditor. For all stages of production, the factory or in this case the bis approved transformer manufacturers have to maintain appropriate controls as well as checks in order to ensure that their product specification conforms to the various requirements of the Standards set by BIS.
According to the drafts of the BIS standards, bis certified transformer companies list need to maintain the following set of measures while manufacturing the product.Article 6.1.1 states that each transformer when tested needs to pass the routine tests that have been administered. If any transformer should fails in any one or more than one of the requirements as specified by the BIS standards, the product shall be deemed unfit for the purpose of marking. Sub article 6.1.1.1 mentions that, although a transformer has been rejected under main article 6.1.1, the transformer may however, be suitably repaired and the defects can be rectified. In this case such transformers which have been repaired must then be tested again and they shall conform to all the routine tests.

Points to be remember while buying a BIS approved transformer
- First of all, you need to look for a reliable BIS approved transformer manufacturer and supplier.
- Choosing right place to buy a BIS approved transformer from and maintaining it is as important as taking care of our assets, so next time your industrial transformer has a problem making sure you go to the right place.
- Check if the manufacturer offers customized transformers to meet your requirements so that you get a BIS approved transformer best suited for the purpose you want to purchase it for.
- Check for the protection of the device you want to purchase, and ask the manufacturer for a guarantee.
BIS Test Reports
- Test Report
- Test report will be issued for the equipment/products tested, at no extra cost, but only upon payment of the final bill of test charges. In case of requirement of additional copies of test report/test certificate, the Customer shall inform the Testing Authority before commencement of the test. Separate charges will be levied for such requests.
- The report will contain the record of the values of test results, the physical condition of the equipment/products during/after the test(s) copy(s) of Oscillogram(s), graphs, drawings, photographs, etc as appropriate.
- Test Certificate
- The sealed test certificate is issued, on request and on payment of additional 10% of the total test charges when an equipment/product/sample of a particular type and rating has satisfactorily passed all the specified tests in compliance with the conditions stipulated in a published National/International Standards.
- This Certificate is issued in justification of the satisfactory rating of the equipment/product/sample for which it is tested.

BIS approved transformer manufacturing process
BIS approved transformer benefits
- As there is an RTCC board with AVR (Automatic Voltage Regulator) LV side voltage stays in want extend by changing tap consequently.
- For changing a tap, shut down of industrial facility isn’t dependable. Be that as it may, due to the on-load transformer, you can change tap in any event, when your manufacturing plant is running.
- Due to the on-load transformer proficiency of the transformer expands, misfortunes of the transformer and other electrical hardware decline brings about low influence utilization and the general existence of the transformer and other electrical gear increments.
- Due to the on-load transformer, the voltage at the LV side stays in limit against the voltage changes from the HV side
