定义
The primary conductor is a critical component in current sensors, typically a solid or laminated conductive element that carries the electrical current to be measured. It is engineered to minimize resistance, reduce thermal effects, and ensure precise current flow for accurate sensor operation. In industrial applications, it often integrates with magnetic cores or Hall-effect devices to facilitate non-invasive current sensing.
工作原理
The primary conductor operates by allowing electrical current to pass through it, generating a magnetic field proportional to the current. This magnetic field is then detected by the sensor's sensing element (e.g., Hall-effect sensor, Rogowski coil, or current transformer), which converts it into a measurable voltage or signal for monitoring and control systems.
