DC current immunity composite core
DC current immunity composite core
DC current immunity composite core is a special electrical component used in DC circuits, which offsets or reduces the DC part of the DC circuit by generating corresponding inductance. Therefore, it is prepared using both nanocrystalline and amorphous materials, fully utilizing their material properties and possessing good DC resistance through heat treatment processes.
Performance characteristics:
(1) Strong resistance to direct current;
(2) High precision, applicable level range 0.5-0.1;
(3) Applicable current range 5-200A;
(4) Excellent high and low temperature characteristics;
(5) High cost-effectiveness.
Application areas:
Anti DC component current transformer for electricity meter;
Power system measurement;
Control anti DC component current transformer.
