Analyze oil to determine circuit-breaker condition
Article Abstract:
Insulating oil analysis in power transformers has been shown to be an effective non-intrusive way of testing the integrity of power transformers. Advances in insulating oil analysis methods now examine dissolved gas, particle profile, moisture, interfacial tension, color, acid number and dielectric breakdown voltage as indicators of potential trouble in the transformer. Insulating oil analysis has proven itself a useful tool in reliability centered maintenance.
