A new model for recovery voltage of oil-paper insulation system
A new model for recovery voltage of oil-paper insulation system
A theoretical description of recovery voltage on oil-paper insulation systems based on interfacial charge movements is proposed as an alternative to traditional RC-circuit model. The traditional model produces responses that are linear superposition of exponential functions. However the recovery voltage observed in actual time-domain measurement does not conform to the exponential descriptions. This is especially true to the tail of recovery voltage which decay sub exponentially at the rate of rather than exponentially. More data points need more time constants to describe because the curve is intrinsically non-exponential. The interfacial charge model also suggests that the recovery voltage of pressboard can be viewed as reflecting two major processes of charge movements and transfer.

Abstract
A theoretical description of recovery voltage on oil-paper insulation systems based on interfacial charge movements is proposed as an alternative to traditional RC-circuit model. The traditional model produces responses that are linear superposition of exponential functions. However the recovery voltage observed in actual time-domain measurement does not conform to the exponential descriptions. This is especially true to the tail of recovery voltage which decay sub exponentially at the rate of rather than exponentially. More data points need more time constants to describe because the curve is intrinsically non-exponential. The interfacial charge model also suggests that the recovery voltage of pressboard can be viewed as reflecting two major processes of charge movements and transfer.
