The emergence of electrical employments geared the indispensable use of electrical cables which became the backbone structures that are widely utilized to distribute power and communication signals throughout nearly all modern systems. This increasing importance of wires made their reliable and safe operation a pivotal issue, especially that they are subject to unwanted modifications and breakdowns mainly distinguished as hard faults (open or short circuits) or soft faults, typically featured by minor alterations as insulation defects, that can lead to drastic consequences if not early rectified. It is worthy to note that our interest in soft faults shoved off from the studies that were conducted on cables and showed that 30% to 50% of detected wiring faults are considered to be soft faults which might be far dangerous than hard ones due to their detection difficulty.
