Introduction
The energy meter is an electrical measuring device, which is used to record Electrical Energy Consumed over a specified period of time in terms of units.
Market Potential
Every house, small factory, business establishment, shops, offices etc. need at least one energy meter to register power consumption. The supplier of electrical raises the bill on the basis reading shown by this meter. The producer of electricity sale the electricity to the electricity boards and boards have to sale this energy to the consumer. Consumer needs to pay the amount against the bill raised by the supplier. The data generate by the energy meter
is the base to raise the bill by power supplier. Because of massive rural and urban electrification programme of Government, there is a good demand for this product. This product is available in single phase and three phases at different current rating as per customer's requirement. Though, newly developed electronic energy meter is also available in the market but in view of simple techonology involved to manufacture this product and for replacement of spare parts, the present demand and future prospect of this product is reasonably good.
Technical Aspects
Process of Manufacture
Energy meter is basically an assembly of electrical and mechanical components. The design of energy meter depends upon which rating of current and voltage upon meter has to work. The components like potential coils and current coils are to be designed in accordance with customer's requirements. Other components like magnets, terminals, Disc and reading registration mechanism are to be designed accordingly. All these components fixed in housing and connection to be made as per circuit designed. Every step needs to be checked, electrical parameters before sub assembly. Complete assembly put on testing bench for final testing to set accuracy of the meter. This testing bench is very important equipment fully computerized. In this bench we have to set power factor frequency, current ratings and speed of rotating disc. When every electrical parameter is checked than meter is to be sent for despatch and ready to install in the customer's premises.
Pollution Control
The Government accords utmost importance to control environmental pollution. The small-scale entrepreneurs should have an environmental friendly attitude and adopt pollution control measures by process modification and technology substitution.
India having acceded to the Montreal Protocol in September 1992, the production and use of Ozone Depleting Substances (ODS) like Chlorofluore Carbon (CFCs), Carbon Tetrachloride, Halons and methyl Chloroform etc. need to be phased out immediately with alternative chemicals/solvents. A notification for detailed Rules to regulate ODS phase out under the Environment Protection Act, 1986 have been put in place with effect from 19th July 2000.
Energy Conservation
With the growing energy needs and shortage coupled with rising energy cost, a greater thrust in energy efficiency in industrial sector has been given by the Government of India since 1980s. The Energy Conservation Act, 2001 has been enacted on 18th August 2001, which provides for efficient use of energy, its conservation and capacity building of Bureau of Energy Efficiency created under the Act.
The following steps may help for conservation of electrical energy:
i) Adoption of energy conserving technologies, production aids and testing facilities.
ii) Efficient management of process/manufacturing machineries and systems, QC and testing equipments for yielding maximum Energy Conservation.
iii) Optimum use of electrical energy for heating during soldering process can be obtained by using efficient temperature controlled soldering and de-soldering stations.
iv) Periodical maintenance of motors, compressors etc.
v) Use of power factor correction capacitors. Proper selection and layout of lighting system; timely switching on-off of the lights; use of compact fluorescent lamps wherever possible etc.
