Reasons for Choosing Rogowski Coils As Measuring Equipment

1、High measurement accuracy: 

The measurement accuracy of Rogowski coils can be designed to be higher than 0.1%, generally ranging from 1% to 3%, which has higher measurement accuracy than traditional current transformers.

2、Wide measurement range: 

Due to the use of non-magnetic cores, Rogowski coils have the ability to measure over a wide range of currents. The same winding can be used to measure currents ranging from a few amperes to several thousand amperes without saturation or nonlinear errors, and has good linearity.

3、Wide frequency range: 

The frequency range of Rogowski coils can generally be designed to range from 0.1Hz to 1MHz, and special bandpass designs up to 200MHz can be used well for transient current measurement.

4、It can measure small currents in restricted areas that other technologies cannot use.

5、There is no electrical contact between the current sensor and the measured current, and the insulation performance is good.

6、Small in size and light in weight.

7、Easy to use: 

The Rogowski coil has a simple structure, is easy to install and configure, is convenient to use, and can quickly measure current.

8、High reliability: 

Due to the absence of moving parts, the Rogowski coil has high reliability and a long service life, reducing the frequency and cost of maintenance and replacement.

9、Good isolation performance: 

Rogowski coils have good electrical isolation performance, which can effectively protect the safety of measuring equipment and the tested circuit.

10、Strong Customizability: 

Rogowski coils with different specifications and performance can be customized according to user needs and special application scenarios, providing personalized solutions.

In summary, Rogowski coils have the advantages of high precision, wide measurement range, wide frequency range, measurable small current, no electrical contact, good insulation performance, small size, light weight, easy to use, high reliability, good isolation performance, and strong customizability, making them an excellent current measurement device.
