Study of the dielectric degradation of XLPE and EPR power cables by switching impulses
The insulation of the high voltage power cable will be placed under higher electrical stress by switching surges during the power system operation. The switching surge weakens the power cable insulation and it leads to ...
The Effects of Switching Impulses on the Partial Discharge Activity and Breakdown Voltage of 15 kv XLPE and EPR cables
A growing trend in the electrical industry is to move away from overhead lines and towards underground distribution. The cables necessary for underground distribution are stressed in various ways, and one of the most ignored ...
Accelerated Aging Study of Machine Winding Insulation under AC and High Frequency Pulse Voltage Application
It is common practice to perform accelerated aging with 60 Hz ac to determine the lifetime characteristics of insulation used in the machine. Comparable breakdown measurements are performed at different voltage levels and ...
Investigation of the influence of dielectric charges on passivation efficiency in SiC devices
Silicon Carbide (SiC) is a wide bandgap semiconductor that is currently of major interest for power electronics applications. SiC-based semiconductor devices and circuits are presently being developed for use in high-temperature, ...
