In forecoming “more electrical aircrafts”, aircrafts will become more compact and light, as hydraulic, pneumatic or mechanical systems will be replaced by electrical ones. The network voltage is expected to increase far above Paschen’s minimum, thus increasing the risk of partial discharges. These discharges, known as silent enemies, may affect the reliability of the system. Moreover, some electrical equipments are located in unpressurized area and their operating conditions (temperature, pressure) may change in a large range. These environmental parameters (and their cycling) have an influence on discharge inception voltage and may even modify its nature. This paper deals with the influence of the pressure on partial discharges and especially on the modification of partial discharges spectra with pressure. Twisted pairs of enamel wires were subjected to repetitive square voltage waveform and sinusoidal voltage at various pressures.
