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 component by generating the necessary inductance. It is made from nanocrystalline and amorphous materials, leveraging their unique properties and undergoing specialized heat treatment to achieve excellent DC resistance.
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:
Anti DC component current transformer for electricity meter;
Power system measurement;
Control anti DC component current transformer.
