In actual scenarios, it is often necessary to accurately measure the current in components or power lines. The standard ammeter usually has limitations and cannot measure the current exceeding dozens of amperes. Although this is sufficient for many applications, it is easy to imagine a scenario where the current is significantly higher:

Electric motor (about 150A)

Railway overhead line (about 1000A)

Generator current of power plant (several kA)

For these high current requirements, you can use current sensor , which converts the high input current to a small but proportional output current. For example, a 1000 a input current can be converted to a more manageable 2a output current. Conversion is based on a scale factor or conversion ratio, calculated as input current divided by output current. In this case, the scale factor is 500.

In addition to measurement applications, the current sensor has a variety of other functions. They are used in control technology and protection systems where the reduced current is conducted to residual current devices (rcd) or control devices not designed for high currents.
