Hi to all,

I want to design the Power Theft Detector. Can anybody help me on this.

I think using TDR which is known as Time Domain Reflectometry we can detect the power theft and also locate the position of power theft. But the problem is how to design the TDR System.

i have no idea about TDR

Thanx Ajay for the Reply :-) :-) :-)

Ok ..... First let me tell about the TDR. it is very simple

( Time domain Reflectometry) is a widely used technique to find the fault occurrence in cable. and the instrument is called as Time Domain Reflectometer or Cable Radar or Echo Meter.In this
1. Sending a well defined voltage pulse down to the Testing line and waiting for the echo. 2. Displaying the sending pulse and echo on Fast oscilloscope screen
3. Analyzing the characteristics of Echo such as Shape of the waveform, Direction, Impedance, Magnitude of the pulse.
4. Measuring the Echo time to find the cable length or distance to fault.

and following are the parameters included this
1. Rise Time of the Pulse
2. Pulse width
3. The amplitude of the Pulse
4. Impedance over the cable
5. PVF ( Velocity of Pulse)

I hope the above details have given clear idea about the TDR
For More Details on TDR Please download the below PDF

[lightbox=image_url|title|group|float]http://rapidshare.com/files/150797434/01_Outstanding_TDRs.pdf[/lightbox]

Now my problem is How we can design the TDR System and How we can make use of this TDR Technique in Embedded system for the Power Theft Detection and Location Over the Transformer Lines which I feel one of the great challenging tasks in the Present scenorio.

Can anyone help me on this.

Hi to all,

I think I need to put the end for the TDR ( Time Domain Reflectometry)



let me have one more idea for this
we know DTMF ( Dual Tone Multi-frequency ) which can be sent over the electric power lines for the communication i.e switching of device ( which is called as Device switching via DTMF) by making use of of DTMF Encoder and DTMF decoder like HT9170.
So can we make of the above technique with some other modifications for the power theft detection. please help me on this.

I think TDR *is* the way to go, but it seems you are the expert around here
Any method that works is likely to specialised and complex, I think you will just have to
invest in some expensive test gear and good books,
sorry

Thanx for the reply

While going through the TDR concepts I got stuck in below condition.

For the TDR to work the Cable should be Metallic and atleast two conductors insulated from each other.



what does it mean .... please help me on this.

I think it just means metallic conductors.. ie copper.
You need at least two conductors to look for unusual
interactions between them.

Hi Experiment UK,

Thanx for the reply,

Ok .... Let me take the example of Electric transformer power lines.
it has got two lines ( Metallic conductors) one is Phase and another one is Neutral.
which are insulated from each other. Is it right or not....

Yes that would be correct, as long as the two lines are together in a cable,
and not six feet apart on big pot insulators

I think working with high power systems may make a difficult job
even harder, and rather dangerous.

Sir,I was doing like thisMCP3901_CS = 0;WriteSPI1(0x01);TempData = ReadSPI1( );TempData <<= 8;TempData |= ReadSPI1( );TempData <<= 8;TempData |= ReadSPI1( );MCP3901_CS = 1;and my problem solved by doing like thisMCP3901_CS = 0; WriteSPI1(0x01); TempData = ReadSPI1( ); TempData <<= 8; MCP3901_CS = 1; MCP3901_CS = 0; WriteSPI1(0x03); TempData |= ReadSPI1( ); TempData <<= 8; MCP3901_CS = 1; MCP3901_CS = 0; WriteSPI1(0x05); TempData |= ReadSPI1( ); MCP3901_CS = 1;

Dear Sir Ref. to the discussion held with under sign, the detail is as under--- We are in weighing scale field since 1986. We are assembling the scales by purchasing the material from out source ( From India and other countries). Now we decide to make our own Card in our decided shape. So we want to develop a universal card , which we can make all types of scales of up 100000 counts with 7 segment LED Display . Also with other features like Printing, Counting, RS232 Etc. And Three Pass words at different levels. And we can edit the Softwear. What else you can provide in this field, also mention. We will pay you the development , softwear and testing charges. And up-gradation charges at time to time. Our web site is modern-scales.com Kindly revert.

Please tell me about pic instruction ADDWF fileName,f ; fileName=fileName+W. Why twice memory access (1)fileName+W,(2)fileName=fileName+W, be able in one instruction cycle. For MOVWF fileName ; memory access once in an one instruction cycle.
