The partial discharge (PD) leads to catastrophic failure of the medium voltage (MV) switchgear insulation. Determination of the PD source (defect) location in high voltage (HV) equipment is very important in the maintenance procedures and in isolating the root cause of PD generation. In this paper. the transient earth voltage (TEV) detection method was used to acquire defect-initiated... https://foldlyers.shop/product-category/other-metal-boxes/
