Conductor overheating an d cable insulation accelerated aging can be caused by temporary increases in the RMS values of the voltages and currents due to stationar y disturbances. Waveform distor tion, unbalance and phase displa cements can be considered among the sta tionary disturbances. For distur bances with short duration, there are no significant reductions in the insulation lifetime, but disturba nces acting for long time peri ods will cause cumulative and detrimental effects. Currently va lid models for insulation aging are employed; the expected power quality distu rbance levels are extracted from power quality databases.
