The sensitivity of partial discharge detection in a high-voltage test environment reduces due to the electromagnetic interference. The quantitative detection and pattern recognition of partial discharge cannot be accurately performed

and it is time-consuming and labor-intensive. This paper proposes a method for generating simulated partial discharge pulses using circuits in the laboratory

and controlling the phase and amplitude of the pulses to output the discharge characteristics of partial discharges. The PRPD spectral output system of partial discharge signal is designed and produced. In this paper

an avalanche transistor is used to generate a pulse voltage with a leading edge time of less than 1 ns to simulate the UHF partial discharge signal. The micro-power comparator

digital potentiometer and other devices are used to control the triggering process of the avalanche transistor to obtain a pulse voltage signal with controllable phase and amplitude. Through the communication between the upper computer and the lower computer

the system can read different types of partial discharge data files

and output different types of partial discharge signals. The original PRPD spectrum of the partial discharge is highly similar to the PRPD spectrum output by the output system. It can be seen that the system can output different types of partial discharge characteristics

and can directly use the partial discharge detection device for analysis and learning

which has high use value.
