Tips: How to improve the performance of ac current sensor?

1. Method of improving accuracy

Primary side wire of ac current sensor shall be placed in the center of the sensor hole, don't place it deflected.
Diameter of the primary side wire shall fill the hole of the sensor, don't leave a big gap.
The quantity of electricity to be measured should be close to the standard measurement rating Ii of ac current sensor. If conditions are limited, please measure the low level of electricity with a high measuring range sensor. To improve the measuring accuracy, the primary side wire can be wound by several circles of N through the primary side hole, so as to ensure that ampere-turns Ni is close to the rated current Ii.

In addition to the above methods, attentions shall also be paid to installation wiring, work environment and instant calibration.

2. Obtain good dynamic characteristics and sensitivity
In order to obtain good dynamic characteristics, namely the quick reaction time and tracking velocity, the primary side wire shall insert the primary side hole solely. And the wire shall be full of hole.
3. The temperature of primary side current line or flat cable shall not exceed 80℃.

Measuring motor current

I used this current sensor for measuring motor current. Motor specifications: AC 380V, three-phase, 7.5kW. I selected current sensor 0-50A measuring range. The effect is relatively good. The error is relatively small, even for small current.

Current sensor type customized

- Measurement range: AC 0-1A
- Output signal: DC0-10V
- Power Supply for 0-10V : 220V AC
- Hole Diameter Selection : 15mm
I had purchased a current sensor with the above specifications.
Due to the characteristics of the current sensor installation site, it is difficult to release the wiring.
Is it possible to custom-made the core of the sensor as a detachable type (open type)?
I would like to know if it is possible to manufacture with the above specifications with the above-mentioned model or open type."

ATO Responded

Sorry, the measuring range of the current sensor you bought is very small, we cannot customize it into a detachable (open) version at present. Usually the detachable (open type) version is suitable for the measurement of that kind of large current, such as the measurement range of 0-1000A or 2000A.
