Abstract

In this paper, a brief description of fiber optic based system for detection of single-phasing faults in 3-phase induction motors used in underground coal mines has been given. The system has an alarm facility which start sounding in absence of power. It also consists of three light emitting diodes of different colors to show the absence of power in a particular phase along with the alarm. Optical fiber, being a dielectric, non-metallic, and non-sparking is an intrinsically safe media and is ideally suited for single phasing faults detection of 3-phase motors used in underground mines or in any other hazardous environment.
