Know everything about transformer testing

Transformer testing is performed to maintain the performance and specifications of the transformer. A transformer is considered to be a vital part of electrical generation and distribution. If the transformer does not work properly, it may affect the complete generation or distribution system. So it is important to ensure that routine transformer testing and maintenance are needed with the help of good quality transformer testing equipment.

 

Why is transformer testing necessary?

 

The requirement for transformer testing is to keep a check on the functioning of the transformer and reduce the chances of failure. Every electrical equipment requires maintenance from some failures. Transformer failures may occur due to mechanical, thermal, and electrical factors. Even insulation breakdown can cause transformer failure. Proper transformer testing can prevent failures of electrical equipment to a huge extent. For that, you may need transformer testing equipment like transformer turns ratio meter, CT polarity tester etc.

 

What are the benefits of transformer testing?

 

Transformers maintain their working capacity and lessen the chances of failure. Transformer testing equipment such as HV transformers testers can boost your transformer's life management. Do you know that reliability and accuracy of transformers can directly impact the reliability of the grid? Failure of such assets can hamper the complete grid. Now, if you plan to replace the HV transformer that requires proper planning and is a costly affair. Nowadays, most industries have embraced a wide range of comprehensive transformer testing equipment which can offer you a whole view of your transformer's health.

 

Transformer testing equipment can be helpful:

 

Transformer testing equipment can help in keeping a check whether the main parts or components of your electrical transformers are working correctly or not. The testing tools check the functions of your complete transformer. They can help in reducing working failure risk and can confirm specifications and good performance of the transformer. You can perform various diagnostic tests on power transformers. This equipment gives an efficient and easy analysis in less time.

 

What are some transformer tests?

 

Some transformer tests are:

 

a) Routine test

 

The routine test is performed to confirm the operational performance of the transformer. Here in this test, LV and HV winding resistance is measured. It can also measure the insulation resistance of LV and HV windings. 

 

b) Polarity test

 

The polarity test is referred to as an induced voltage direction in the transformer's two windings (primary and secondary). When the connection of two transformers is done parallel, then the polarity test has to be considered a good connection of your transformer.

 

c) Special test

 

A special test is performed to receive vital information useful to users. In special tests, it tests like short circuit tests, measurement of acoustic noise level, a zero-sequence impedance of three-phase transformers etc.

 

Transformers play a vital role, taking from generation of electricity to utilization of electricity. Therefore regular transformer testing and maintenance are recommended to check whether your transformers are working properly, to prevent future failure risks due to some issues.
