摘要（英）：

The invention discloses an oiled paper insulation partial discharge inception voltage test system which comprises an alternating current high voltage power supply, a high voltage capacitance-resistance divider, an oiled paper insulation sample tank, a partial discharge measuring instrument and an upper computer. The alternating current high voltage power supply is connected with the oiled paper insulation sample tank. The high voltage capacitance-resistance divider is connected with the oiled paper insulation sample tank. The partial discharge measuring instrument is connected with the oiled paper insulation sample tank, and collects partial discharge signals inside an oiled paper insulation sample. The upper computer is in two-way communication connection with the alternating current high voltage power supply and the partial discharge measuring instrument. According to the oiled paper insulation partial discharge inception voltage test system, the partial discharge measuring instrument is adopted for testing the partial discharge inception voltage of oiled paper compound insulation with different temperatures and different electrode structures, and the partial discharge inception voltage of the oiled paper insulation system is accurately measured.
