High Voltage Surge Protective Devices Recent Developments

Self-healing or self-restoration technologies aim at performing fault location and isolation, and service restoration of power distribution systems in an automated fashion. Some of the intrinsic benefits of this smart distribution component are increased reliability, more efficient use of manpower and resources, and increased operational flexibility. Selfhealing technologies are an inherent part of the Smart Grid and are expected to play a pivotal role in modern and future distribution systems. The switchgear, information technologies and communications infrastructures required for the implementation of self-healing schemes are also the foundation for other advanced smart distribution applications such as automatic system reconfiguration and system optimization. Therefore, an increasing number of self-healing initiatives are being pursued and implemented by utilities around the world as part of the power delivery modernization. The objective of this panel is to discuss recent experiences, advances and trends in the application of self-healing technologies on power distribution systems.
