Important Facts About Transformer Bushings: An Ultimate Guide

Have you ever wondered what the purpose of bushings in the transformer is? If yes, then you must read this blog. Transformer bushings carry the lines from the transformer. There are two types of lines: low-voltage and high-voltage lines. This provides insulation between the body of the transformer and the live wires, eventually preventing chances of short circuits. Finding a reliable transformer bushings manufacturer in India is essential. Let’s dive deeper into the subject below.

Understanding The Principles of Transformer Bushing

As mentioned above, the bushing helps keep the wires insulated from the transformer body. Bushings are created using insulation material specially curated to control the voltage level.

Can bushings lead to oil leakage in the transformer?

Yes! Bushings can lead to an oil leakage from the end point of the transformer. Atmospheric conditions, miss installation, aging, or bushings are the primary reasons for this.

Extremely cold or heat can result in rusting, which will eventually cause a metal loss in the bushing pockets. This can lead to cracks in the oil seal which causes leakage at the end.

How do insulators differ from bushings?

Insulators and bushings are vital components of the whole power system. Let’s have a look at the main differences between insulators and bushings.

● Insulators can be either hollow or filled. On the other hand, bushings are always hollow to allow the wires to pass.

● Insulators are used in equipment, whereas Bushings are utilized in Transformer and shunt reactor circuit breakers.

While the most common type of testing is oil testing, you can implement the electrical testing method to get precise results. You can purchase premium quality transformer bushings from the reputable Transformer Bushings Manufacturer in India for product assurance.


What is a Transformer Bushing? 


The transformer Bushing is a kind of insulating structure that forms the passage for current-carrying, energised conductors through the grounded tank of the transformer. Either the conductor is built into the bushing, like a bottom centred one, or drawing in a separate conductor through the centre. This can be a draw lead or draw rod bushing.  


Types of Transformer Bushings 


Transformer Bushings usually have two principles, a solid/bulk type and capacitance graded bushing. The latter is also known as the condenser type.  

The manufacturers make solid bulk bushings using porcelain or epoxy insulators. You can mainly utilise this for low voltage windings of the transformer. On the other hand, capacitance graded bushings are designed for high voltage ratings and high voltage windings.  


The failure of transformer bushings is considered a leading cause of transformer failure. Hence, the transformer asset owners must consider its quality. There is typical bushing failure because of moisture ingress, lightning strikes, misapplications, corrosive sulphur, broken connections, etc. 


Why Should You Test the Transformer? 


Routine electrical testing is mandatory, and you should perform it every 3-5 years for the utility companies. For electrical testing, you need to de-energise the unit and isolate it to perform complicated processes. There are several reasons why performing electrical testing of the transformer is essential.  


  1. Acceptance Testing.
  2. Bringing the Transformer Out of Storage  
  3. After the Transformer Trips Offline 
  4. Verification of the Oil Test that is unacceptable 


Transformer Bushings Maintenance 


  • Cleaning  


Before testing, you should clean them of the dust, impurities and dirt particles. You can administer a simple bushing cleaning method – elbow grease and soft rags. If the bushings are dirty, cleaning with solvents is also helpful. Other methods are pressure water washing with CO2 and more. 


  • Visual Inspection  


Check the bushings for cracks and other damages. If the damage is severe, the current leakage can become excessive, showing carbon trackings on the surface. Flashovers can also occur if you do not clean these bushings periodically. 



  • Thermographic inspection    


You can also inspect high voltage bushings with infrared cameras to check loose connections.
