A transformer is a passive electrical device that transfers electrical energy from one electrical circuit to one or more circuits. A varying current in any one coil of the transformer produces a varying magnetic flux, which, in turn, induces a varying electromotive force across any other coils wound around the same core.

Three-phase transformers are used in three-phase circuits to step up and step down the voltage according to the needs in a power system. You know that electric power is generated
An electrical substation is an integral part of a generation, transmission and distribution system. A substation can interrupt or establish electrical circuit, change the voltage, frequency or other characteristics of
Transformer bushing types are categorized based on their material, manufacturing, and design mainly into the following types: OIP (Oil-Impregnated Paper) Bushing RIP (Resin Impregnated Paper) Bushing RIS (Resin Impregnated Synthetic)
A current transformer (CT) is a type of transformer that is used to measure AC current. It produces an alternating current (AC) in its secondary which is proportional to the AC
Amazed why secondary of current transformer should not be open? If it is left open it may destroy the current transformer. So it is very important that the secondary of
What is the Percentage Impedance? The percentage impedance of a transformer is marked on most nameplates – but what is it and what does the Z% figure mean? The
An induction motor may be considered to be a transformer with a rotating short-circuited secondary. The stator winding corresponds to the transformer primary and the rotor winding to the transformer
Gas-insulated substations (GIS) have been used in power systems over the last three decades because of their high reliability, easy maintenance, small ground space requirement, etc. This article is an
What is Load Forecasting? Electrical energy cannot currently be stored in large amounts. It has to be generated whenever there is a demand for it. It is, therefore, imperative for
In today’s post, we will go through a video that explains the working of single phase and three phase transformers in detail. We have already discussed the working principle of a transformer and Why Transformers are Rated in kVA, Not in kW? Watch the video below..
What is the Rectifier Transformer? Rectifier transformers are different from normal power and distribution transformers because they are special transformers made for industrial application. A Rectifier transformer is a special application
According to IEEE/ANSI Std. an electrical bushing is defined as “an insulating structure, including a through conductor or providing a central passage for such a conductor, with provision for mounting
There are different types of connection employed for three-phase transformers. The star-star (Y-Y) connection of three-phase transformers is the most economical type of connection for small current and high voltage transformers. The
