Switching Overvoltage Stresses on Sheath Voltage Limiters: Failure Investigation
Sheath voltage limiters are used in long underground cable systems, when sectionalized cross-bonding is applied for sheath bonding design and protect the sheath bonding system against transient overvoltages. Read More >
Pollution Design of HVDC/UHVDC Outdoor Bushings
Different bushings are used to connect the AC line to the DC line at HVDC substations. Depending on converter station design, these can be placed indoors or partially outdoors and therefore exposed to ambient pollution. Read More >
