Lightning Impulse Voltage Stresses In Underground Cables
Journal of Physics: Conference Series, 2023 Abstract Underground power cables are crucial for transmission and distribution. Lightning can stress their insulation, but not directly. So, impulse cable testing is studied. This research examines the cable’s transient response to standard and non-standard lightning impulse voltage waveforms.
