Method for measuring currents in multiphase power objects and the current-voltage transducer for the execution of this method

摘要

method of measuring currents in cumulative electricity facilities, in particular in tru00f3jfazowych railway systems of generators, generator - transformer blocks, transformers and electricity energy stations, designed especially for use in automatyce zabez pieczeniowej these objects, in which the current (t) are coupled together with cewkami magnetically measuring (cp)together with arms subsequently measuring (p) voltage, characterised by the fact that in the measuring coils (cp) and measuring sections (p) voltage measuring individual tracks pru0105dowych (t) put in series compensation coils (ck), coupled magnetically with the pru0105do and (t), neighbouring the measuring track pru0105dowym (t),which offset the impact pru0105dowych currents adjacent tracks (t) on the measuring coils (cp) measuring sections (p) voltage measuring pru0105dowych individual tracks (t).pru0105dowo - tension transducer, for achieving this way, built with several tracks pru0105dowych (t), of which at least one is measuring track happened (t), coupled magnetically with the measuring coil (cp), which is then joined with a measurement (p) napiu0119c ia is suchin the measuring circuit (cp) and a measuring arm (p) voltage measuring track pru0105dowego (t) is included in series at least one coil offsetting (ck), coupled magnetically with the track pru0105dowym (t), which pru0105dowym measuring track (t).
