Tape Wound Core for DC Immune Current Transformer
The current transformer DC immune is used to detect AC currents wherever DC offsets exist. The current transformers create a voltage when current flows. They are mainly made for detecting AC currents in a circuit. So with a DC bias, the AC measurement can distort.
Product Introduction
DC current immunity composite cores is combined with amorphous and nanocrystalline cores
The current transformer DC immune is used to detect AC currents wherever DC offsets exist. The current transformers create a voltage when current flows. They are mainly made for detecting AC currents in a circuit. So with a DC bias, the AC measurement can distort.
DC immune CTs are capable of measuring AC and DC component with high accuracy
So even though it has intrinsic high phase displacement, it has an excellent accuracy to satisfy class 0.5 smart meters in addition to measuring multi harmonics in the high accuracy. The characteristics are the supreme linearity throughout the whole dynamic current range and very low current loss.
The Applications of DC immune current transformer are:
DC immune electronic energy meters
Measurement of DC components in the AC line
Cores of precision current transformers for watt-hour meters and transmitters etc. instead of Permalloy and silicon steel sheet.
Cores of measuring and protection current transformers equipped at substations.
DC current immunity transformers in electronic energy meter/watt-hourmeter
Metering transformer in electronic power system
The features are：
Strong DC current immunity
High accuracy grade,Applicable transformer accuracy range 0.5-0.1 Class
Applicable Current range 1.5-200A
Good temperature stability
●Excellent linearity & precision
●Good performance in DC factor
●Double-core-stack design; high initial permeability and no saturation with DC bias.
●Light weight and low cost, much lower price than cobalt-based alloy.
●Excellent stability
