**Current Sensor*
1. **Purpose* Current sensors are used to measure the current flowing within a circuit, determining its magnitude and direction. They are commonly employed for monitoring current loads, detecting current anomalies, and various applications in power systems.
2. **Working Principle* Current sensors can operate based on various principles, including inductive, Hall effect, and current transformers. Inductive current sensors measure current by detecting the magnetic field changes it induces. Hall effect sensors utilize the Hall effect to measure current, and current transformers function as per the transformer principle to reduce current to a measurable range.
