Tag: Transformer bushings

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.

● Insulators can also be made from rubber, but with Bushings, it’s not possible.

● Insulators cannot be filled using di-electric, but the same is possible with Bushings.

● Insulators are widely used in electrical equipment we use daily to prevent malfunctioning in wiring. However, you cannot use Bushings in daily electrical equipment.

How many Bushings does a Transformer need to have?

Firstly, please note all types of transformers and ratings contain Bushings. But its count depends upon certain factors like the number of phases and type of connection at low and high voltage sides.

Single Phase Transformers:

A single-phase transformer has four bushings on it.

Three Phase Transformers:

Depending upon the connection type, a three-phase transformer can have nearly 6 to 7 bushings.

● Delta-Delta connection
● Wye-Wye connection
● Delta-Wye with a neutral connection
● Wye with neutral Delta connection

In any electrical supply facility, you would notice the usage of different components. All these components have their own usage. These are important for smooth electrical supply. One of the important electrical components used in electrical supply is transformer bushings.

Brief About Transformer Bushings:

Transformer bushings are capacitance-graded electrical components. These are formed by many conductive inserts. These connect the bushing’s central conductor to the ground. A transformer bushing plays an important role in evenly spreading out the voltage. It can also regulate the voltage around the central conductor.

Popular Types of Transformer Bushings Found in India:

While buying the components from a reliable transformer bushings manufacturer, you can find a variety of items. We discuss more about the common types of bushings used in India below.

Solid Ceramic Bushings:

These are simple designed conductors, having a single conductor inside a ceramic insulator. It is a common choice for units that handle low power. The design of the bushings can come to help if the power supply is at a premium.

SRI Bushings:

These are modern-day transformer bushings that are rapidly becoming a replacement for ceramic bushings. If you operate modern high-end transformers, SRI bushings can come in handy for your use. It is much more beneficial than traditional ceramic bushings as it can prevent the wear and tear of the conductor. However, these bushings cannot handle transformers canaltaronja.cat with high voltage variations.

RIP Bushings:

Composite RIP Bushings are also known as resin-impregnated paper bushings. These are a common choice among electrical workers. The finishing of the bushings is performed by treating mineral oil with resin-soaked paper. You can commonly find ceramic and composite variants of the RIP Bushings.

OIP Bushings:

The Oil Impregnated Bushings (OIP) are commonly used in power transformers. These are much more convenient and long-lasting than other ceramic bushings. These are devoid of partial discharge, which makes them a unique choice among others. If it fails to operate, the performance of the transformer can get affected significantly.

These are some important variants of transformer bushings that you can commonly find in industrial operations. To source them from a reliable source, contact Reliance Potteries.
