Component Specifications

Definition
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.
Working Principle
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.
Materials
High-conductivity copper (Cu) or aluminum (Al), often with tin or silver plating for corrosion resistance; insulation materials include PVC, polyethylene, or epoxy coatings for electrical safety.
Technical Parameters
  • Conductivity >98% IACS for copper
  • Current Rating Up to 5000A
  • Frequency Range DC to 100 kHz
  • Temperature Range -40°C to +85°C
  • Insulation Resistance >100 MΩ
Standards
ISO 9001, IEC 61869, UL 508
