Abstract:

Power quality is one of the most talked about topics these days. Both the power utilities and customers are quite concern with the quality of the power supply, whether it be the power generated by the power utilities or the power consumed by the customers respectively. They need these supplies to be at its optimum value so that the cost is efficient; otherwise problems such as over voltage, under voltage, voltage swell, voltage sag, noise and harmonic caused by the disturbances in power supply could be disastrous. Several methods ....etc

Hi
This is mechatronis project , where Most commercially available low-cost DC-AC converters (Frequency control / inverters) give a square wave of 50Hz output. This is sufficient for a number of devices, especially for devices operating with a transformer. The professional training that a sinusoidal output signal is generated, can also be used to control motors, but is much more expensive. The intention is to build this type of control with the microcontroller. The intention is that through a screen and some buttons speed and run speed is adj ....etc

Working Model of Transformer

INTRODUCTION

The transformer is a device used for converting a low alternating voltage to a high alternating voltage or a highalternating voltage into a low alternating voltage

PRINCIPLE

It is based on the principle of mutual induction that is if a varying current is set-up in a circuit induced e.m.f. isproduced in the neighboring circuit. The varying current in acircuit produce varying magnetic flux which induces e.m.f. inthe neighboring circuit

magneto optical current transformer installed in india

An accurate electric current transducer is a key component of any power system instrumentation. To measure currents, power stations and substations conventionally employ inductive type current transformers with core and windings. For high voltage applications, porcelain insulators and oil-impregnated materials have to be used to produce insulation between the primary bus and the secondary windings.

The insulation structure has to be designed carefully to avoid electric field stresses, whi ....etc

ABSTRACT

This paper describes in detail, field experiments performed on a single-phase, distribution transformer to study the behavior of transformer terminal parameters during internal winding faults. A custom-built transformer provided with external taps was used for these tests. The taps were used to stage various internal winding faults in the transformer. Terminal values of voltages and currents were monitored and the results presented. A comparison of these results with simulation results is also presented

A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction. Electromagnetic induction produces an electromotive force within a conductor which is exposed to time varying magnetic fields. Transformers are used to increase or decrease the alternating voltages in electric power applications.

A varying current in the transformer's primary winding creates a varying magnetic flux in the transformer core and a varying field impinging on the transformer's secondary winding. T ....etc
