Precautions in Connecting Booster Transformer

The following precautions are to be taken while connecting a booster transformer in the traction circuit 

  • 1.  Booster transformer should be able to withstand severe mechanical stresses which will develop due the current of thousands of amperes under the conditions of short-circuit.  


  • 2.  Primary winding insulation of the booster transformer should be kept at 25 kV, while secondary winding insulation is kept at 3 kV because a high potential is created in the secondary winding under fault conditions.


  • 3.  The booster transformer should not be located near the signals or the places where the train is likely to stop.

Alternating Current

  What Is Alternating Current? An  alternating current  can be defined as a current that changes its magnitude and polarity at regular intervals of time. It can also be defined as an electrical current that repeatedly changes or reverses its direction opposite to that of Direct Current or DC, which always flows in a single direction as shown below From the graph, we can see that the charged particles in AC tend to start moving from zero. It increases to a maximum and then decreases back to zero completing one positive cycle. The particles then reverse their direction and reach the maximum in the opposite direction after which AC again returns to the original value completing a negative cycle. The same cycle is repeated again and again. Alternating currents are also accompanied usually by alternating voltages. Besides, alternating current is also easily transformed from a higher voltage level to a lower voltage level.

SOLAR TRANSFORMERS

  The transformers required for wind power and solar DPV require special design features to meet the challenging operating conditions. The industry today has developed different types of transformers for the application. The last few decades have seen very rapid development of renewable energy, especially, distributed photovoltaic (DPV) and wind power. It is estimated that at least 40 per cent of electricity generation by year 2040 would be from renewable energy sources and this would give appreciable reduction of the present level of carbon dioxide emissions of about 10 billion tons per year. The transformer industry is rising to this challenge and has developed special transformers for the DPV generation and wind generation. Transformers are critical components in solar energy production and distribution. Historically, transformers have ‘stepped-up’ or ‘stepped-down’ energy from non-renewable sources. There are different types of solar transformers including distribution, station, su
