Testing an Emergency Luminaire Circuit Using a Fault Dictionary Approach (original) (raw)

2008 11th IEEE Workshop on Design and Diagnostics of Electronic Circuits and Systems, 2008

Abstract

In this paper a model for emergency luminaire circuits is utilized for building a fault dictionary so as to be used for circuit fault diagnosis. Simulation and measurements used for testing an emergency luminaire were performed in order to verify the emergency luminaire circuits behavior. Simulation results were compared to the experimental data acquired with the help of an oscilloscope and a measuring system, which offers real-time storage of current and voltage waveform measurements. Simulations of the fault-free circuit and faulty circuit instances proved to be in good accordance to the measured data. A fault dictionary is built and is successfully used to diagnose the most commonly encountered faults in the circuit.
