CURRENT TRANSFORMER COIL FOR ENERGY METER

Mainly used in single phase or three phase electronic energy meter, serving as current sampling tool or the current measuring tool for general industrial instruments and measuring control equipment. The secondary coil and magnetic core adopt vacuum epoxy sealed package, excellent waterproof and anti-seismic performance and good insulating property. The primary coil can use copper bar or copper wire for connection.Accuracy class can be chose: 0.1 class, 0.05 class.It satisfies the relative requirement of IEC61036 Energy Meter Standard. Note: Wire length and colors can be customized.Current SpecificationCurrent (input/output)Load ResistanceOperating FrequencyRatioAccuracy Class5（60）A/5mA10～25Ω50/60 Hz1000:10.05, 0.15（60）A/2.5mA10～25Ω50/60 Hz2000:10.05, 0.120A/10mACurrent Error And Phase ErrorAccuracy ClassCurrent error r ±（%）phase error ±（’）0.01In0.05In～Imax0.01In0.05In0.2In～Imax0.050.10.058420.10.20.11585DC Measure Accuracy (D type)≤±2.1%Other ParameterWithstand Voltage Of Primary & Secondary4000VrmsIsolation Resistance≥1000MΩ（Testing Voltage:500VDC）Operating Temperature-50～+75℃Stock Temperature-55～+85℃Packing DataNet /pcspcs/CTNWeight/CTN Cubage/CTN
