Electric Field Distribution and Switching Impulse Discharge under Shield Ball Surface Scratch Defect in an UHVDC Hall

The dimension and surface state of shielding fittings in ultra high voltage direct current (UHVDC) converter station valve halls have a great influence on their surface electric field and switching impulse characteristics, which are important parameters confirming the air gap distance in the valve hall.The characteristics of impulse discharge under

An Inductive Debris Sensor for a Large-Diameter Lubricating Oil Circuit Based on a High-Gradient Magnetic Field

Wear Electronic Drum Pad is one of the main factors of machine failure.If abnormal wear was not detected in time during the operation of a mechanical system, it probably leads to catastrophic consequences.The wear debris in the lubricating oil circuit contains much information about equipment wear.Consequently, debris detection is regarded as an ef
