- Abstract:
- Replacing a lamp in an outdoor installation, like roadway lighting, requires a lot of time and money. The proper maintenance strategy of installed lighting-system components is an essential element in ensuring that systems perform as designed and consequently ensure the safety. The paper presents a method for evaluating the residual life of High Pressure Sodium road lamps and for detecting incoming fault. The proposed method is based on the frequency domain analysis of the lamp current that changes its harmonic content in consequence of the aging.
