Electricity stealing is a common thing to occur nowadays. Stealing electricity from the distribution of the electric supplier will greatly reduce their annual turnover of profits. If consumers that implement any techniques to steal electricity, they must be investigated thoroughly before any legal action can be taken upon them. One of the commonest methods to steal electricity is to tamper with the electric reading meter. But as the time goes by, electric meter has somewhat become tamperproof by becoming digitalized. Electrical thief will without a doubt, come up with a new way to steal electric. Identification will be difficult when all of the supply cables are invisible to the investigator. At the same time, lots of mechanism and circuitries are being deployed to prevent electricity theft being discovered. Unauthorized Tapping Detector (UTD) will give clues whether the cable is tapped or not and where to investigate further. This paper presents an approach in recognizing illegal tapping. This project involves the software simulation part and the experimentation of hardware assembly. This experiment utilise the comparison properties of frequency in the assembly setup before and after tapping position of cable. Results from both methods were analysed and conclusion is made based on the results.
