Abstract

Light intensity is a resultant of Kerr effect measurement which later can be translated to electric field as well as charge density distributions in dielectric liquid. The light intensity can be measured either with photodiode or camera but measurement with both detectors has not been done yet. This study focuses on the comparison of light intensity measurement using Kerr effect with simultaneous detectors of photodiode and high speed camera. Hence, a pair of parallel electrodes is used in the experiment under high DC electric field. Propylene carbonate is used as the test liquid with Kerr constant, B of 1.41x10−12 mV−2. From the measurement results obtained, the light intensities from both detectors were compared and showed significant results as compared to the predicted light intensity ratio.
