Inductively coupled probe for the measurement of partial discharges [PDF]
Review of Scientific Instruments, 2008 Partial discharges are a transient phenomena whose measurement is remarkably important for electrical equipment diagnosis and maintenance. These discharges appear in the measurement circuit as very narrow current pulses of some nanoseconds. Therefore, discharge pulse detection is a particularly difficult problem, especially because they are superposed ...
