Abstract
The moisture in the transformer has always been a matter of concern for its end users - power companies, utilities, and industries. Water is an enemy of electrical equipment, and the transformer is no exception. Several methods have been employed to deal with this challenge, which gets tougher with the age of the transformer. As power continuity must be maintained in most applications, it is not possible to take the transformer out of service for moisture removal. Moreover, the bigger the transformer, the longer the shutdown period and the higher the financial losses. Therefore, online moisture management systems are being adopted
over conventional offline oil filtration systems.
