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%. |

Questions about this model
How do I get a price for the DC immune mini current transformer
Email [email protected] or message us on WhatsApp with the model, the ratio, the accuracy class, the burden in VA and the quantity.
What is the burden and why do you ask for it
The burden is the total termination impedance seen by the transformer: the measuring instrument, the connecting leads and the winding itself. Accuracy class cannot be guaranteed without it, and long lead runs add resistance that has to be counted.
Can this model be customised
Ratios, secondary current and mounting can often be adapted within the same frame. Send us the requirement and we will confirm what the frame allows.
