Abstract : Included are methods of testing the various aspects of tap changing devices for power transformers, chapters on measuring contact pressure strength, intermediate contact resistance and torque; testing for the electrical resistance of insulation, for resistance to short circuiting and for mechanical durability. Also a method for checking the sequential action of contacts and their switching off capability is described. (Author)
