摘要
Sensor calibration plays an important role in instrument development and accuracy. This paper presents a method to calibrate current and voltage sensors specially dedicated to power quality measurements which can significantly reduce the distortions introduced by the sensors. The first approach to sensor calibration is based on the response of sensors to DC values imposed by a calibrator. The second method is an AC calibration, where a 50 Hz power signal is applied to the sensors also through a calibrator. The calibration coefficients are obtained by minimizing the output distortion. The minimized output distortion is assessed by the signal to noise and distortion ratio (SINAD) at the output of the sensor correction module.
