Current Sensor

Current sensors are devices used to measure and monitor the flow of electric current in a circuit. They are commonly used in various applications, including power systems, industrial automation, and electronic devices.

In the supply class Electrical And Electronic Properties Measuring And Testing Instruments, there are several types of current sensors available. Some of the commonly used current sensors include:

1. Hall Effect Sensors: These sensors use the Hall effect to measure the magnetic field generated by the current flowing through a conductor. They are non-contact sensors and can measure both AC and DC currents.

2. Rogowski Coils: Rogowski coils are flexible current sensors that can be wrapped around a conductor to measure the current. They are commonly used for high-frequency and high-current applications.

3. Current Transformers (CTs): CTs are widely used in power systems to measure high currents. They work based on the principle of electromagnetic induction and provide an isolated output proportional to the primary current.

4. Shunt Resistors: Shunt resistors are low-value resistors placed in series with the load to measure the current. They work based on Ohm's law and provide a voltage drop proportional to the current.

5. Current Probes: Current probes are clamp-on devices that can be attached around a conductor to measure the current. They are commonly used for troubleshooting and maintenance purposes.

These are just a few examples of current sensors available in the Electrical And Electronic Properties Measuring And Testing Instruments supply class. The specific type of current sensor to be used depends on the application requirements, such as the range of current to be measured, accuracy, and interface compatibility.
