Power transformers are the most important part of an electrical grid. The use of Oil filled Transformers is also vital in the supply of electricity across the town, village, or the desired location. 
In this article from the manufacturer “Electrical Transformer”, you will know and explore more about Oil filled Transformers. 
How Do You Define Oil Immersed Transformer
An oil-filled (oil-immersed) transformer is a type of voltage transformation device that uses oil for maintaining a lower temperature. This is not like a dry-type transformer. The installation of this type of transformation is based on the welded steel oil tank. 
These types of transformers contain an oil tank including insulation oil. When they are in operation, the emission of heat from the iron core, the oil transforms into the insulation oil and reaches the cooling medium. 
The size of capacity decides the natural ...

Types of Oil-Filled Transformers 
Oil Filled Transformer Manufacturers consider two types of designs to produce the required products such as:

One-phase oil-filled transformer

One-phase Oil-immersed transformer (50KVA, 25KVA, or 15KVA)

Three-phase Oil Immersed Transformer:

Operations of Oil filled Transformers

Safety 

Every working personnel on the grid should aware of certain necessary facts and take appropriate safety precautions. Each employee or working associate should wear appropriate clothing and safety gear like protective eyewear, gloves, and hard hats. 

Pre-operation inspection: 

There must be a thorough inspection to make sure that every component is in its appropriate place and in good working condition. The inspection is to avoid the chances of damage and corrosion in the functionality of an oil-filled transformer. 

Installation

The right type of transformer should come into place as per the requirement of the client following different licensed orders. The installation process may need certain clarification from the electrician as well. Also, the customer will get approval in case of using any specialized equipment. 

Connection

According to the transformer’s specifications, associates from the Oil Filled Transformer Manufacturer will help a client to complete the tasks relevant to the connection of the required equipment. 

Testing

Before starting the operation of the oil-filled transformers, they should be verified first to check every type of necessary functionality.  

Operation

The checking of equipment will let you know about the functions of the oil-immersed transformers. Once they are active, they will aid in the supply of electricity at the correct voltage and frequency. 

Maintenance

Regular maintenance is necessary to conduct. They will help you to know about the current conditions and functionalities of the transformer and let you identify any potential issues. Here is the list of activities that should be conducted in an oil Oil Filled Transformer: 

Inspections
Analysis of oil samples
Electrical measurements
Test of equipment
Checking temperatures by using a heat-sensitive camera
Monitoring (offline and/or online)

Troubleshooting  

If the operator finds any issue, he will run the necessary tests to identify and name the fault on time. 

Disposal

When the transformer doesn’t function to its extent (at the end of its life), it should be disposed of appropriately.Oil filled Transformers
