This project shows another way of developing faulty pilot cable detector based on time-domain reflection (TDR). The faulty pilot cable detector is implemented on Arduino microcontroller. Since it is digital based, it is easily programmed and the circuitry is not as bulky as analogue type. Using the Arduino-based microcontroller, the faulty at the pilot cable can be detected by injecting the TDR pulse signal into the inspection cable or wire. The edge and reflected signals from the inspection cable are captured and measured by the Digital Sampling Oscilloscope. Then, the pattern of healthy or faulty cable with its location can be determined by analyzing the reflected pulse signal (step waveform). This system has been successfully tested on 30m cable with shorted and opened conditions. The whole system to detect faulty in the pilot cable are coded using C language.
