DC Immune current transformer

Product description:
- Accurate DC measurement; - Suitable for a wide range of current(from 1.5 to 100A); - Linear output current, high precision; - Compact, delicate appearance; - Encapsulated with epoxy resin to ensure strong insulation ability. DC Tolerance - In normal condition,the power net is sinusoidal AC at loop, positive nd negative waves are symmetry. But in some special Conditions, the circuit have DC, then positive and negative waves will not be symmetry. Common current transformer would be saturation under this condition, and the meter used this CT have large error, even can not work, so just DC lmmunity CT can solve this problems. - As following figure to test the DC error, 0.1 accuracy CT will be controlled within ±3.0%,0.2 accuracy class CT will be controlled within ±6.0%.
