Abstract :
A portable Schering bridge which is applicable for power factor, dielectric loss, and capacitance tests on condenser bushings and other equipment of higher capacitance in the field is described in this paper, and operating procedure is given. Such tests are desirable for forestalling failures of equipment. Although earlier power factor tests on bushings have been made in the field, this is probably the first application of the Schering bridge to field tests.
