Questions to Ask Before Buying an Industrial Transformer in India

A transformer is a piece of essential equipment used to power electrical machines. It is used both for small household equipment and for heavy industrial machinery. 

If you are looking to buy an industrial transformer from one of the many transformer manufacturers in India, there are a few questions that you need to ask. This will ensure that you find the right machine for your requirements. Following are some of those essential questions.

1.  What is the load or kVA requirement? 

The first thing that you need to ask is what is the loading requirement. Transformer manufacturers in India produce machines with varying load capacities. If there are any expansion plans in the future then that also needs to be factored in while deciding the load of the transformer.  

2.  How many phases are required? 

Usually, transformer manufacturers in India make single and three-phase transformers. The single-phase transformers are suitable for households and small equipment, while the three-phase ones are used in big industries.  

Based on your requirement, you will need to decide which type will suit your needs best.  

3.  Which type of transformer to opt for? 

Next, you will have to ask whether you need an oil-cooled or dry-type transformer. The oil-cooled transformers are usually more affordable and suffice for most requirements. However, if you are looking for an easy to install machine then you might consider a dry-type transformer.  

The space available will also dictate which transformer is more suitable for your needs. For example, a corrugated transformer is more suited for smaller installation spaces.  

4.  What is the voltage requirement? 

Transformer manufacturers in India make transformers that provide voltage as per individual need. You will have to first decide what is your specific output. That will give the voltage requirement of your transformer.   

5.  What is the maximum loss permitted? 

If you are buying a transformer in India, then you need to adhere to the losses as specified in IS 1180. You cannot buy a transformer that produces higher losses. If you want a more efficient transformer with lower losses, then that also needs to be specified.   

While these are the most basic questions that need to be asked before buying an industrial transformer in India, here are a few other additional points that you can consider for a better experience-  

1. Whether any specific clearances are required. You should also check if you need any tests to be done other than the standard ones. 

2. What is the length of the warranty period? This is especially important in case repairing costs are high. 

3. How safe is the transformer and whether you require any upgraded insulation and fire protection. 

4. What is the environmental impact of the machine?  In India, there are several options available in the market to choose from. However, the right questions must be asked before making an informed decision as to which industrial transformer to buy. Doing so will ensure that you buy the right machine for your specific business requirements and avoid any hassles in the future.
