“…Domestic and foreign researchers have concluded through a large amount of measurement data that the corona discharge pulse current in transmission lines has a double-exponential distribution characteristic, which means that the waveform of the corona pulse current can be represented by a double-exponential function. This function contains two time constants, among which one is used to describe the rise time of the pulse current and the other is used to describe the fall time of the pulse current [1]. The double exponential function of the corona pulse current is shown in Formula (1).…”

In the partial discharge test of the shunt reactor of the ultra-high voltage transmission line, the corona discharge caused by high voltage interferes with the test. To further study the propagation rules of the corona pulse on the line side in the transmission line during the ultra-high voltage partial discharge test, based on the parameters of an actual transmission line, the ATP-EMTP electromagnetic simulation software was used for modeling. The propagation rules of corona pulses in the transmission line were analyzed in detail through the simulation model. As the propagation distance increases, different frequency components show different degrees of attenuation. The higher the frequency is, the faster it attenuates.
