The primary types are Hall-effect sensors (for DC and AC), Rogowski coils (for AC with high frequency), current transformers (for AC power systems), and shunt resistors (for precise DC measurements).
Current sensors provide galvanic isolation through magnetic coupling (Hall-effect, CTs) or air-core designs (Rogowski coils), preventing direct electrical connection between the measured circuit and measurement system for safety and noise immunity.
Accuracy is influenced by temperature variations, magnetic interference, linearity errors, frequency response, and aging of materials. Proper calibration and temperature compensation are essential for maintaining precision.
