Instrument Current Transformer CYECVT1-36N Single Phase Electronic Combined Current and Voltage Transformer Indoor
The products have designed base on IEC60044-8, GB/T20840.8-2007&IEC60044-7,GB/T20840.7-2007 standards, and customers special design service. This series are utilized LPCT&Rogowski coil to meter current in circle, conduct Resistor divider to measure voltage. Installed in any switchgear with High tense voltage below 10kV, compatible with electric instrument, digital measure and protective equipment, able to conduct multifunction such as measure, control, protection and data transmission etc simultaneity.
Remarks: Upon request we are glad to offer transformers according to other standards or with non-standard technical specs..
