Abstract :
In most of the engineering applications, air is used in conjunction with solid insulation. The interface forms a weak point for the occurrence of partial discharges (PD). Therefore it becomes essential to know the behaviour of the PD in such a system. The work presented in the paper is a study of the PD corona pulse shape in air-solid interface under varying conditions of gap and pressure. Some results on the pulse height distributions of the PD in air-solid interface are also highlighted
