Suppression Measures of Partial Discharge at Rod–Plate Connection in Composite Tower

Energies, 2023
Rods and plates at the connections in composite insulating material towers are commonly fixed to each other by metal bolts, which may cause electrical field distortion at the connections. So, the rod–plate connections are prone to partial discharge under
