Abstract

This paper presents a power over fiber (PoF) voltage and current sensor to be used in high voltage applications. The current sensor is based on a microelectronic hall sensor and the voltage sensor is based on a capacitive voltage divider. The measured signals are transmitted from the unit at high voltage to the unit at ground potential using an innovative pulse width modulation (PWM) multiplexed method. This technique is experimentally demonstrated by measuring voltages and currents up to 1.6 kV and 100 A, respectively.
