## EMF Equation of Transformer and Voltage Turn Ratio

Consider an AC voltage of magnitude “V” having frequency “f” is applied to the primary side of the transformer. ac flux Φm is set up in the transformer core, this flux links with the both primary and secondary winding of the transformer.…

## Open Circuit Test and Short Circuit Test on Transformer( SC/OC)

Mainly two tests are carried out on the electrical transformer which are the open circuit test and short circuit test of the transformer also known as the SC and OC tests. Key takeaways: The purpose of these tests is to…

## Conservator Tank of Transformer- Construction, Working and Types

The conservator tank is the main part of the transformer, It provides space for the expansion of oil and acts as a reservoir for transformer oil. In this article, we will explore the construction, function, and working principle of the…

## Scott Connection of the Transformer-Application

The Scott connection of the transformer is a standard method of connecting two single-phase transformers to perform the three-phase to two-phase conversion and vice versa. Scott connection of transformer is also known as T – T connection. In Scott-T connection, two…

The working principle of the transformer is based on Faraday’s law of electromagnetic induction. The three-phase power transformer is the main device of every power system. the main function of transformer is to step up or step down the voltage…

## Transformer Oil BDV Testing Procedure

The dielectric strength of transformer oil is known as BDV or break-down voltage. A Transformer Oil BDV test is performed to find the dielectric strength of transformer oil. BDV is the minimum voltage withstand the capacity of transformer oil without…

## Transformer Polarity test, Additive, Subtractive ,Procedure,diagram

The transformer is the main device of the transmission and distribution network hence its reliability is important in every aspect. The transformer must be able to deliver the required power to load. single transformer unit is used for distribution purposes…

## Buchholz Relay in Transformers | Construction,Operation and Principle

What Is Buchholz Relay? Buchholz relay is a mechanically operated relay that is used to protect the transformer from internal faults that occur inside the transformer tank like an inter-turn fault. Buchholz relay is an oil and gas-operated device. The…

## Back to Back test of Transformer (Sumpners Test) Procedure

The efficiency and regulation of the transformer can be calculated using open circuit and short circuit test on the transformer but to measure temperature rise during operation, it is necessary to conduct a full load test on the transformer. for…

## Parallel Operation Of Transformers- Conditions, Reasons

Transformers are said to be connected in parallel operation when their primary connected to a common supply and secondary connected to a common load. The function of the transformer is to deliver power to the locality, city. But in some cases, a…
