Estimation of water content in power transformers in service by polarization and depolarization current measurements

This paper focuses on the comparative analysis of two different methods for water content estimation in power transformers. The first method under study is the Karl-Fisher coulometric method that measures the water content in oil and correlates it to the water content in paper. Use of four well know...

Summary:This paper focuses on the comparative analysis of two different methods for water content estimation in power transformers. The first method under study is the Karl-Fisher coulometric method that measures the water content in oil and correlates it to the water content in paper. Use of four well known correlation curves is compared and discussed in the paper.
