Monitoring of the electrocardiogram during normal activity using Holter devices has become standard procedure for detection of cardiac arrhythmias, transient ischemic episodes and silent myocardial ischemia. Existing devices mostly record "twenty-four" hour activity and then perform off-line record analysis. We present realization of an intelligent(More)
This paper presents a fault classification technique for transmission lines based on the fault sequence components, for fast and reliable operation of protective relays. First, symmetrical components of fault current and voltage signals are extracted. Next, the fault type is classified using the zero and negative sequences. To realize the faulted phases in(More)
