Transformer inrush current or magnetization inrush current is a transient input current drawn by a transformer during its energization. Depending on several factors, the magnitude of the magnetization inrush current…
Noise is an unpleasant, unwanted and annoying sound. Transformer noise, quite commonly known as the ‘humming sound or buzzing sound’ of transformer, is one of the major problems with large…
Open circuit test and short circuit test are conducted to determine the core loss, copper loss, and equivalent circuit parameters of a transformer. In this article, in addition to the…
In order to understand the equivalent circuit of a transformer, we suggest you read Ideal transformer first and then come back and continue from this point. What is an equivalent…
A transformer is an AC device used to step down or step up voltages. To visualize the current flow and other circuit properties of a transformer, certain assumptions are made,…
Electricity does not exist naturally in any useful form. It has to be generated from any other sources of energy such as solar, wind, hydro, thermal, atom, etc. Photovoltaic cells…
You might have come across various types of transformers in your daily life either knowingly or unknowingly. This article illustrates various transformer types. Before getting into classification, here is a…
Voltage regulation of transformers can be a little tricky to understand. Every piece of equipment is designed to operate at a particular voltage or voltage range. Therefore, it is a…
An electric transformer is a device used to step up and step down ac voltages. This article will help you understand their basic concepts, construction, the principle of operation, tests…
What is the purpose of transformer oil? Transformer oil functions as a coolant as well as insulating material. It also enables transformer protection during internal faults. It is chemically stable…
