Power systems of the future. 2

For pt.1 see ibid., vo.20, no.1 (2000). The assets and working philosophy of individual utilities will in large measure be reflected by the modernization of their power systems in the next 20 years. The power system of the future should enable utilities to: be more competitive with their overall strategies; provide better service; better manage their assets; extend equipment life; improve diagnostics; and develop reliability-centered maintenance. This paper features FACTS (operating systems, custom power, and improved capacitors), electrical insulation, distribution cables (extruded dielectrics, polymeric insulation, underground vault explosions, fault location, smart cables, neutral and ground corrosion and protection), and transformers (compact transformers, ferroresonance, and solid state transformers).
