On measuring key parameters of an electro-impulse deicing system

Abstract

The peak current and vibration peak acceleration are two important parameters in the electroimpulse deicing system. Available data on two parameters are sparse. An experimental setup to measure the peak current and vibration peak acceleration in the electroimpulse deicing system is presented. The measurement is performed in the icing wind tunnel. Rogowski coil’s principle on pulsed current measurement is applied in the electroimpulse deicing discharge current circuit. It is found that calculated results agree with the measured trend. A piezoelectric vibration acceleration sensor is adopted to measure the vibration peak acceleration. Test results show that when the peak current varies linearly, the vibration peak acceleration increases with the increase of discharge voltages and its variation is approximately linear. The experimental results in the electroimpulse deicing system demonstrate that the proposed measuring method is accurate and reliable.
