Abstract
The paper presents a design for a Magneto-Optic Residual Current Device (MORCD) using ferrofluid as the sensing material. As the selection of suitable magneto-optic material was seen as the critical phase in the design, a novel Magneto-Optical performance Indicator is proposed and verified using known optical materials. It was experimentally established that the designed MORCD is sufficiently fast and capable of detecting residual current as low as 1.51 mA.
