Non-destructive analysis of HV asset insulation

TD/PF is a form of offline testing that comprises a non-destructive diagnostic technique that evaluates the condition of the insulation in assets such as motors, generators, and cables.

Measurements quantify the dielectric losses in the asset insulation, and can indicate potential issues such as moisture ingress, degradation or aging of the insulation.

A benefit of TD/PF testing is its ability to monitor changes in insulation over time, so by periodically measuring and recording these values within Atlas by Monitra™, analysis of condition trending helps to identify progressive degradation or anomalies in the insulation. As a result, TD/PF testing can serve as a vital tool in predictive maintenance programs.
