This diagnostic process evaluates the situation {of electrical} insulation inside cables. It measures the loss angle, or the tangent of the loss angle, of the insulation when subjected to an alternating present (AC) voltage. The next worth signifies larger vitality dissipation as warmth, suggesting deterioration or contamination of the insulating materials. For instance, an aged cable exhibiting elevated readings doubtless requires evaluation for potential alternative or restore.
The importance of this analysis lies in its potential to proactively establish insulation weaknesses earlier than catastrophic failures happen. By monitoring developments in these measurements, upkeep personnel can schedule preventative upkeep, minimizing downtime and enhancing the general reliability of energy distribution programs. This system gives a non-destructive technique for assessing cable well being, contributing to improved security and diminished operational prices. Traditionally, this technique has been used for predictive upkeep for many years.
