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. A better worth signifies better power dissipation as warmth, suggesting deterioration or contamination of the insulating materials. For instance, an aged cable exhibiting elevated readings probably requires evaluation for potential substitute or restore.
The importance of this analysis lies in its skill to proactively establish insulation weaknesses earlier than catastrophic failures happen. By monitoring traits in these measurements, upkeep personnel can schedule preventative upkeep, minimizing downtime and enhancing the general reliability of energy distribution methods. This system affords a non-destructive technique for assessing cable well being, contributing to improved security and decreased operational prices. Traditionally, this technique has been used for predictive upkeep for many years.
