Abstract:

Transformers are one of the primary device required for an AC (Alternating Current) distribution system which works on the principle of mutual induction without any rotating parts. There are two types of transformers are utilized in the distribution systems namely step up transformer and step down transformer. The step up transformers are need to be placed at some regular distances for reducing the line losses happening over the electrical transmission systems. Similarly the step down transformers are placed near to the destinations for regulating the electricity power for the commercial usage

Abstract:

In the industrial field, transformers are used as a step-up voltage and are used as a step-down level. In a loaded transformer, the power that comes out of the transformer (transformer output power) is not always 100% because there are losses when channeling to the load. Both losses caused by current flowing in the copper wire, losses caused by alternating flux in the iron core, and losses caused by Eddy current in the iron core which result in the outgoing power (output power) from the transformer to the load is not the same as the incoming power (input power) to the transformer.

Abstract:

The electrification of society, increasing renewable energy sources and mobility charging lead to new loading patterns for power transformers. Dynamic load conditions induce enhanced mechanical stress on the transformers’ windings, potentially causing degradation of the solid insulation over time and compromising the transformer’s short-circuit withstand capability. Thermal expansion of the windings, caused by losses in the copper conductors, occurring as the transformer is loaded, increases the stress. Conversely, magnetic losses in the core and tie plate expansion contribute to a reduction i

However, no detailed models of transformers, developed in Simulink/MATLAB®, were reported in the literature. Hence, in this paper, a virtual laboratory consists of models of single-phase transformers was built for the first time. The proposed models are easy to use and modify, and allow all machines’ parameters to be altered for students to replicate easily to support and enhance the lea

The transporters in DC convey travel in a solitary bearing. Batteries and thermocouples are the main part of DC. A DC voltage can create a positive measure of standard power.An AC voltage from the generator can exchange their energy after they go round through a transformer.</em>

Abstract:

For over a century, a transformer act as a crucial part of the high voltage system. This also acts as an energy alteration device that is used to step-up and step-down voltage for power distribution from power generation to the consumers. Maintaining a transformer is important since a single mistake can lead to a vast amount of problems in a high voltage system in terms of cost. Thus, nowadays, many researchers study the important parts of a transformer, making it to function more effective. One of the studies involves improving treatment in the insulation medium of transformers to improve its

Abstract:

Some industrial applications require high step-up and step-down voltage gain. The transformer less buck-boost converter has high voltage gain than that of traditional buck-boost converter without extreme duty cycles. A transformer less buck-boost converter with simple structure is obtained by inserting an additional switched network into the traditional buck-boost converter. The two power switches of the buck-boost converter operate synchronously. The operating principles of the buck-boost converter operating in continuous conduction modes are presented. A new buck- boost converter is presente

Abstract:

The thyristor-controlled phase-shift transformer (TCPST) is an effective means of controlling power flow, exhibiting a simple structure and a long operating life. However, conventional TCPSTs are limited in their ability to regulate the phase-shifting angle, necessitating the matching of the step-up/down transformer to control the amplitude of voltages. Therefore, this paper puts forth two distinct structures of TCPSTs, each of which is capable of regulating both the phase-shifting angle and the amplitude of voltages: the two-core step-up/down thyristor-controlled phase-shifting transformer (T

Abstract:

This paper presents a hybrid electromechanical transformer that passively transfers electrical power between galvanically isolated ports by coupling electrodynamic and piezoelectric transducers. The use of these two complementary electromechanical transduction methods along with a high-Q mechanical resonance affords very large transformations of voltage, current, or impedance at particular electrical frequencies. A chip-size prototype is designed, simulated, fabricated, and experimentally characterized. The 7.6 mm × 7.6 mm × 1.65 mm device achieves an open-circuit voltage gain of 31.4 and 48.7

Abstract:

The presence of moisture in the insulation of power transformers accelerates the degradation of both paper and oil, thereby increasing the risk of unexpected failures. Due to the hygroscopic nature of cellulose, the insulation can retain up to 8% moisture after the transformer manufacturing process. Reducing this moisture content is crucial in extending the operational lifespan of transformers. The drying cycle of paper insulation is a critical step in power transformer manufacturing, directly influencing the insulation’s longevity and overall performance.

<strong>The main concept of the project here is to generate a high voltage DC from a single phase AC with the help of the capacitors and diodes connected in a ladder network. This concept is often used in electronic appliances like the CRTs,TV picture tube,and o scilloscope and also in industrial appliances. It is also possible to generate up to 10KV DC from this single phase supply,but owing to safety concerns and reasons,this system limits the generating voltage to a 2KV output by limiting the capacitor and diode multiplication factor to about 8.</strong> <strong>https://www.ijiert.org/paper
