Open Circuited Underground Cable Distance Locator

It is inevitable to find a critical solution in maintenance environment of electric power applications to find extended length of power cables using electrical means. This paper explains about length measurement of cable which can be extended for finding the location of open circuit point on a power cable using passive electrical parameters like capacitance. For the parameter calculation micro controller assisted with display devices and resistive circuit are used. The microcontroller use algorithm to find the capacitance of the underground cable. The algorithm also calculates the time charge ratio, with the help of passive parameters like current limiting resistance and specific capacitance of cable. The time charge ratio thus helps the microcontroller to calculate the length of the cable. Keywords - Power Cable, Capacitance, Micro Controller, Display
