UNIVERSAL AXLE COUNTER FOR RAILWAYS

Axle counters were developed as a substitute for track circuiting. Two models of axle counters known as single entry/exit axle counter

and multi entry/exit axle countersNEED FOR AXLE COUNTERS :

• Monitoring of berthing tracks in station areas and yards.• Monitoring of point zones in station areas and yards.• Automatic signaling systems.• Block section monitoring (between stations) through axle counters

using multiplexers with cable or radio communication (18 GHz).• Level crossing warning system.

TYPE OF SYSTEMS :  There are four types of system

used in the Indian Railways.• One Device (1-D) System.• Two Device (2-D) System.• Three Device (3-D) System.• Four Device (4-D) System.

Radiant Energy

Solar energy is radiation produced by nuclear fusion inside the sun’s core.

It takes millions of years for the energy in the sun’s core to make its way to the solar surface.

It takes 8 minutes to travel 93 million miles to earth. (186,000 miles per second)

The Greenhouse effect traps some of the heat making life on earth possible.

PV Array Fields

IN ORDER TO GENERATE LARGE AMOUNTS OF ELECTRICITY WHICH CAN BE FED INTO THE ELECTRIC GRID, LARGE NUMBER OF ARRAYS CAN BE WIRED TOGETHER TO FORM AN ARRAY FIELD.

Component• One PV cell only produces 1 or 2 watts of electricity, which isn't enough power for most

applications.

• To Increase power groups of solar cells are electrically connected and packaged into packaged weather-tight modules and arrays to provide useful output voltages and currents to provide a specific power output.

• A PV System typically consists of 3 basic components.

• PV cells - Electricity is generated by PV cells, the smallest unit of a PV system,

• Modules - PV cells are wired together to form modules which are usually a sealed, or encapsulated, unit of convenient size for handling.

• Arrays – Groups of panels make up an array.

Conversion Efficiency

The conversion efficiency of a PV cell is the proportion of sunlight energy that the cell converts into electrical energy.

This is very important because improving this efficiency is vital to making PV energy competitive with more traditional sources of energy, such as fossil fuels.

The first PV cells were converting light to electricity at 1 to 2 percent efficiency.

Today’s PV devices convert up to 17 percent of the radiant energy that strikes them into electric energy. (40% NREL)

Photovoltaic's

Photovoltaic systems convert sunlight directly into electricity, and are potentially one of the most useful of the renewable energy technologies.Also known as solar cells, PV systems are already an important part of our lives. The simplest systems power many of the small calculators and wrist watches we use everyday.

SELF EVALUATION• These 30 days Industrial Training has

led me to understand the various designing, assembling and the manufacturing processes of equipments in the industry, CEL.• It has also enhanced my knowledge

about the functioning and management of an industry, which I am sure, will be beneficial to me in my career.
