Study of the moisture capacity of adsorbents used in protectionand service systems of power (auto) transformers

The article is devoted to the issues of selection and research of adsorbents for their effective use in complex services and provision of power transformers. Based on the developed methods, the moisture capacity of adsorbents in transformer oil was empirically established for the first time. The existence of differences in the moisture capacity of adsorbents in humidified transformer oil and in an atmosphere with high relative humidity has been proven. The obtained moisture capacities of adsorbents in different environments are proposed for use as reference values in analytical algorithms of multifunctional automated systems for restoring the insulation of power transformers for digital indication of the resource of adsorbents in order to prevent the processes of desorption of hazardous moisture and ensure their timely replacement/regeneration.
