Assessment of PD severity in gas‐insulated switchgear with an SSAE
IET Science, Measurement and Technology, 2017 Scientific partial discharge (PD) severity evaluation is highly important to the safe operation of gas‐insulated switchgear. However, describing PD severity with only a few statistical features such as discharge time and discharge amplitude is unreliable.
