Overvoltages caused by the interruption of small inductive transformer currents
IEEE Transactions on Power Systems, 1988The interruption of small inductive currents can cause high overvoltages, which may overstress the dielectric strength of the equipment. Based on detailed dynamic models for the circuit breaker and the transformer, a variety of parameters which influence these overvoltages is systematically investigated by digital simulation.

Proceedings of the American Institute of Electrical Engineers, 1915
Reasons are given for the selection of initial inductances as a means for calibrating current transformers, the most important of which is the wide use to which they may be put besides the calibration of current transformers. The design and manufacture of the apparatus is described, reasons being given for the choice of the form of the secondary coils ...

Bearing fault detection using wavelet packet transform of induction motor stator current
Tribology International, 2007Induction motor vibrations, caused by bearing defects, result in the modulation of the stator current. In this research, bearing defect is detected using the stator current analysis via Meyer wavelet in the wavelet packet structure, with energy comparison as the fault index. The advantage of this method is in the detection of incipient faults.
