Which current transformer is more accurate?
Precision Current Transformers: These CTs are designed for high-accuracy applications and are often used in instrumentation and metering systems where accuracy is crucial. They typically have high turns ratios and low phase shifts.
Rogowski Coils: Rogowski coils offer excellent linearity and accuracy, especially at higher frequencies. They are often preferred for measuring high-frequency currents and in applications where physical size and weight are critical factors.
Hall Effect Current Sensors: These sensors utilize the Hall effect to measure current and are known for their accuracy, especially at low currents. They are commonly used in electronic circuits and power monitoring systems.
Magnetoresistive Current Sensors: These sensors offer high accuracy and linearity across a wide range of currents. They are often used in automotive, industrial, and power distribution applications.
When selecting a current transformer, it's essential to consider factors such as the required accuracy, frequency range, load conditions, and environmental factors. Additionally, certification standards such as ANSI or IEC may also dictate the acceptable level of accuracy for specific applications.
