Magnetic Oil Gauge is also referred to as MOG. it is a device that is fitted on the conservator tank to monitor the transformer oil level. The MOG is a small circular dial shape window placed on the side of…
Voltage control is performed by changing the transformer turn ratio. This is achieved by providing Tapping on the transformer winding. In a tap changing transformer, taping is either provided on the primary or on the secondary winding of the transformer.…
There are in general two types of transformer Shell type and core type transformer These two types differ from each other in the manner in which winding wound on the magnetic core. Core type Transformer In core type, the magnetic…
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…
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…
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…
The vector group of transformer shows the phase difference between the primary and secondary sides of the transformer. There are different ways in which transformer high voltage and low voltage winding is connected. Based on HV and LV winding connections,…
Transformers are essential components in electrical engineering, playing a crucial role in power transformation. Understanding Transformer Losses, the factors that influence their efficiency and performance is important for optimizing their operation. Resistive Loss (Copper Loss) Resistive loss, also known as…
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…
