Yash High Voltage Ltd.- Understanding the Importance of Bushings for Transformers( for H.V side and L.V side )

 


In order to protect and insulate the high-voltage (HV) and low-voltage (LV) sides of a transformer, bushings are a crucial component. They serve as a bridge between the external circuit and the transformer, enabling the efficient and secure flow of electrical energy.

The transformer's high voltage winding is connected to the HV side bushing, which can resist high voltages. The LV side bushing, on the other hand, is attached to the transformer's low voltage winding and is built to resist lower voltages.

The transformer's safety and dependability are greatly influenced by the insulation material used in the bushings. Porcelain, polymer, and oil-impregnated paper are the three insulation materials for bushings that are most frequently employed. These materials have strong mechanical capabilities, great insulating qualities, and resistance to environmental elements including moisture and temperature.

Transformer bushings must be tested and maintained on a regular basis to ensure appropriate operation and guard against potential failure. Capacitance and power factor testing, tests for insulation resistance, and partial discharge tests are a few of the frequent tests carried out on transformer bushings.

In summary, bushings are a critical component of transformers that play a vital role in ensuring safe and efficient energy transfer. Proper selection, installation, and maintenance of bushings are essential for the reliable and long-term operation of the transformer.

What is a Transformer Bushing?

Image
In electrical engineering, the term "bushing" refers to a hollow electrical insulator that allows us to safely pass an electrical conductor through a conducting barrier without creating an electrical connection with it, such as the case of a transformer or a circuit breaker. Porcelain typically makes up a bushing. In actuality, however, a number of alternative insulating materials, including polymer, ceramic, glass, etc., might also be employed for the same function.       When a substance possesses an electric charge, an electric field is created. Consequently, when a current-carrying conductor is positioned close to a material at zero potential, the field strength can increase to a very high value, especially in situations where the electric field lines are compelled to bend sharply around the substance. The bushing in this case regulates the size and strength of the electric field, which lessens the electrical forces acting on the insulating material. Transformer Bushing&#

RIS Bushing in Transformer: What It Is and How It Works

High voltage power transformers use RIS bushing, often referred to as Resin Impregnated Synthetic bushing, as an electrical insulator. It is constructed of a composite material with outstanding mechanical and electrical insulating qualities that is composed of glass fibres and epoxy resin. We shall go into great detail about RIS bushing in this article, including what it is and how it functions.  What is RIS Bushing? An insulating element called a RIS bushing is utilised to physically separate the transformer tank or wall from the high voltage circuit. It is a sturdy cylindrical structure made to endure the significant electric stress that the transformer produces. Epoxy resin, which has exceptional insulating qualities and mechanical strength, is infused into the bushing. How Does RIS Bushing Work? A barrier is created by Putting bushing between the transformer tank or wall and the high voltage conductor. Since it offers a channel for the electric current to travel through the insula
