Cable testing and diagnostics is a process through which the condition, performance, and reliability of the wire or cable used in the power or communication system are evaluated. This testing determines whether there is any damage, degradation, or defect in the cable, which can cause major hazards in the future. This evaluation is mainly done with the help of insulation resistance test, time domain reflectometry (TDR), voltage withstand test, partial discharge analysis, and thermal imaging technology. Through these tests, hidden problems inside the cable, such as insulation weakness, corrosion, connection deviation, or short circuit, can be identified.
Cable testing and diagnostics are very important in power distribution, industrial plants, substation, and infrastructure development projects. Doing this process regularly reduces the risk of costly cable changes and ensures uninterrupted and safe power supply to the system. The use of modern technology makes it possible to analyze cables quickly and accurately, which saves both time and money for the organization. Proper diagnostics ensure long-term performance and safety.
