Indoor Current Transformers

Support Current Transformers (Small Design) The SGS types current transformer are maintenance free cast resin indoors current transformers for rated voltages up to 36 kV according to IEC 44-1 (former IEC185) VDE 0414 or OVE-P20-1/1994 standards. ? Rated primary currents up to 2500 A ? Primary changeable up to 2x600 A ? Rated short-time thermal currents up to 50 kA rms / 1 sec (120 kA peak) ? Accuracy classes up to 0.2S ? Frequency 50 or 60 Hz ? Up to 3 measurement and/or protection cores ? The secondary terminals are arranged in a waterproof sealable box (type of protection IP53) which allows official calibrating and thus usage for account metering. ? The current transformer with particular values of rated power and short-time thermal current are determined by the respective values of accuracy class, rated primary current and instrument security factor. Please contact our representative or our factory directly for a detailed current transformer definition.
