The Influence of Atmospheric Overvoltages on High-Voltage SF6 Substations [PDF]
, 2011 Very fast overvoltages are characteristic of high-voltage metal-enclosed SF6 insulated substations. During the transient phenomenon, on the SF6 substation enclosure an undesired, short-lasting induced overvoltage may appear, which cannot be prevented ...

Impact of maximum back-EMF limits on the performance characteristics of interior permanent magnet synchronous machines [PDF]
, 2006 Interior permanent magnet (IPM) synchronous machines are vulnerable to uncontrolled generator (UCG) faults at high speed that can damage the inverter. One approach to reducing this risk is to impose limits on the maximum machine back-EMF voltage at top ...

Anomalous‐Energy Runaway Electrons Originating in Fast Ionisation Wave During Pulsed Gas Breakdown
High Voltage, EarlyView.ABSTRACT Anomalous‐energy runaway electrons (RAEs), whose energy exceeds the maximum potential difference across the discharge gap, are widely observed in various plasma phenomena. This study investigates the origination of anomalous‐energy RAEs in fast ionisation waves (FIWs) formed during pulsed gas breakdown.
