1,129,908. Current transformers. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 27 Oct., 1966 [3 Nov., 1965], No. 46554/65. Heading H1T. [Also in Division H2] Current transformers CT are coupled to individual neutral conductors C 1 connected to a star point SP and forming part of a multiphase coupling arrangement (see Division H2) between the output terminals of a generator and a transformer, the conductors C 1 being hollow and liquid-cooled (e.g. by oil or sufficiently pure water) and supported in individual gas-filled sheathings SA by insulators IN which permit thermal expansion of the conductors. |
