Abstract

499,239. High - frequency current measurements ; current transformers. SIEMENS & HALSKE AKT.-GES. Feb. 17, 1938, No. 5011. Convention date, March 2, 1937. [Class 37] [Also in Group XXXV] In measurements of highfrequency currents with annular core current transformers, rectifiers and direct current instruments, errors due to the increase of capacitance displacement currents with increasing frequency are reduced by locating the ends of the transformer winding on opposite sides of the core. The winding consists of two uniformly distributed parallel connected parts 3, 4 with the ends 3<1>, 4<1> and 3<11>, 4<11> connected together. The measuring apparatus described in Specification 481,081 is disclaimed.
