Our aim is to identifying the best technologies readily available and also pursuing development
of new technologies and translating these to viable solutions that will benefit the society.One of our excellent product is
KAVAJA THEJAS (Enlightening and safeguarding the power)
Power is the soul of world which is related to electricity and is very essential and convenient
energy source in our day to day. Kavaja thejas results a solution for enlightening and safeguarding
the power. Mainly kavaja thejas focusing on the automatic meter reading and line failure detection.
Electric power reaches our homes from transformers installed in the locality. The consumption of electric
power is measured using energy meter installed at home. The existing meters are either an electronic energy
meter or an electro mechanical meter. It is a common practice that the company sends meter reading personnel
to the consumer premises once in a month or so and record the reading, then calculates the energy charges
based on the prevailing tariff rates, prepare the bill and forward to the consumer. The consumer, on
receipt of the bill, proceeds to settle the bill by paying the amount at the electrical section office or
through online banking resources. It is totally a manual procedure and involves personal effort and
valuable time. However, this process could be automated using computerized system and communication
technologies already been established in the technical world.
Smart energy meters using GSM, Bluetooth, GPRS etc. also have some network installation problems,But all
these system has so many disadvantages. A major problem with electromechanical type meters is their easy
prone to tampering, leading to a requirement of an electrical energy monitoring system. These are very
commonly used in domestic and industrial applications. In the case of electronic or energy meters .These
meters might be analog or digital. In analog meters, power is converted to proportional frequency or pulse
rate and it is integrated by counters placed inside it. In digital electric meter power is directly measured
by high end processor. Here we can explore the possibility of a computerized system installed in the
electrical section office located at the consumer area communicating with a smart energy meter at consumer
premises and do the needful elegantly and automatically. For this power line communication techniques
could be exploited and can be employed as physical layer of communication medium. Hence kavajathejas will
promises the solution for all above
Our project consist of Two sections:
An automatic meter reading system that can be utilized to read the meter reading of domestic
A power line failure reporting system.
The system overview is indicated in below figure. The dotted and dot-dash lines represent
communication of information over the existing power line using power line modems.
Automatic meter reading system consists of two different sections one of which is placed on the
customer’s premises and other on the KSEB office. The residence unit monitors the regular KWH meter
and count the unit that are being used. Each of the customer unit has being assigned a unique code
number. When the master unit at the KSEB office wishes to enquire about the reading it sends out
a request signal along with the corresponding code number of the residence unit. Then the residence
unit accepts the request signal and sends out and interrogation signal along with the code number
of the corresponding residence unit. The residence unit sends out the unit that it has measured
until that particular time and does the billing for that customer can be generated. We can also
calculate separate bill for peak hours.
The power line failure reporting system consists of two different sections one of which is placed on
the distribution transformer and other on KSEB office. The distribution transformer unit monitor the
load across the transmission line. Each transmission line on the distribution transformer consist of
this system with unique code or address. The KSEB unit continuously monitors the distribution transformer section.
If there is any error occur in the load or any line breakage will occur in the transmission line the distribution
transformer section corresponding to it, will send a signal to the KSEB unit.
Both units are controlled by their own microcontrollers.
