Aim:
This system automatically sends SMS to customer for EB bill cost of each two Months using GSM and auto billing with SMS reply systems. The system will work as auto billing system. Mobile ad hoc networks are the future of wireless networks. Why? Because they're practical, versatile, simple, easy to use and inexpensive! We will be living in a world where our network instantly updates and reconfigures itself to keep us connected anywhere we go. These networks provide a new approach for wireless communication and by operating in a li ....etc

Prepaid Electricity billing system using GSM technique

In conventional electricity billing system, the bill is taken after the utilization of energy. This system has many problems such as the human errors in taking readings and during keeping records. To overcome all such problems we are developing the prepaid electricity billing system This system consists of one card placed at consumer end, which will be connected to the meter. It takes pulses from meter as input and accordingly decreme ....etc

ABSTRACT



Because of high requirements in power, efficiency, installation space and weight, the design of electrical machines for hybrid electrical vehicles is a particular challenge. This seminar describes a comparative study allowing the selection of the most appropriate electric-propulsion system for a parallel hybrid electric vehicle (HEV). This seminar is based on an exhaustive review of the state of the art and on an effective comparison of the performances of the four main electric propulsion systems, namely the d ....etc

1.Zero voltage regulation in a transformer occurs at :
(A)zero p.f. lead 
(B)unity p.f.
(C )leading p.f.
(D)lagging p.f.

2.A parallel plate capacitor has 15 p.F capacitance. If the linear dimensions of the plate are doubled and the distance between the plates are also doubled, then new value of capacitance would be :
(A)15uF
(B)30 uF
(C )60 uF
(D)7.5 u.F

3.Resistance of a 230 V 100 W bulb is R1 and that of a 230 V 75 W is R2. Then,
(A)R1= R2
(B)R1 > R2
(C )R1 < R2
(D)R1 - 2R2

4.The current in a series ....etc

Prepaid Electrical Energy Meter (PENERMET)
EMIF Module
Energy Measurement Interface Module
It is a prefabricated electronics module based on ADE7755 Energy Measurement Chip (EMC). The chip contains both ‘Analog Signal Processing’ and ‘Digital Signal Processing’ circuits for precise and accurate noise free measurement of electrical power consumed by a load.
The chip is factory calibrated to generate 1600 cef pulses at the end of consumption of 1 kWh of electrical energy. This electrical energy meter that uses this chip is call ....etc
