Vibration signals are obtained by putting three sensors on relevant position on the cylinder head. The technology of wavelet transform is applied to extract feature information under normal and misfire operation, feature in time domain of vibration signal is analyzed and single cylinder relative energy in time domain is computed to judge fault cylinder without the top dead center signal, which can...
This paper is concerned with the design and development of an on-line condition monitoring system for large power transformers utilizing signals such as transformer vibration, voltages, currents, temperature and state of switches. The system consists of two parts which communicate each other via Ethernet or series port. The formal is a front-end computer subsystem used for data acquisition and processing,...
