A novel system has been devised to eliminate power theft by automatic release of high voltage pulse in the transmission line in response to the command received by the remote termination unit (high voltage source) from arduino in the event of theft being detected. Due to high voltage pulse in the transmission lines, the pilferer's appliances drawing powers illegally by way of tapping get impaired. This operation is transient (for 1-5 seconds) and during this time the supply of voltage for the normal consumers is kept suspended. However, in case of emergency, i.e., when the normal supply cannot be disturbed, the bypass mode is activated so that consumers continue to get un-interrupted power supply, and during this period the process of theft elimination is kept suspended. The actual working of this novel system has been demonstrated by simulating the process in Proteus 8.6. The process thus developed is effective and reliable.
