    Partial discharge (PD) pulses are considered to be generated after application of overvoltage across a cavity. Their magnitude is proportional to the n-th power of overvoltage. It decreases with an increase in cavity space and moisture content. Very long time lags for PD inception, such as even a day, was confirmed. This phenomenon is associated with PD's statistical time lag in the number of free... View full abstract»

    In substituting sequential stress aging for simultaneous multi-factor aging, the interactions between the factors of influence should be expressed in each experimental equation for single-factor aging as a change in the coefficients with time of aging. Then, if all single-factor aging characteristics can be confirmed experimentally, the characteristic equation for multi-factor aging can be derived... View full abstract»
