Blackouts on high voltage (HV) transmission lines occur due to harsh weather and non-climatic reasons such as human errors and mechanical failures. While it is impossible to prevent all such situations, utility officials and contractors can be equipped to meet such emergencies.


This paper discusses: (1) the economic impact of climatic events in the USA and economic justification for having Emergency Restoration (ER) plans and, (2) emergency restoration procedures for downed transmission lines in Oman. Key aspects of emergency restoration procedures are discussed.

Keywords: Economic impact, Emergency, High voltage, Restoration, Transmission lines, Blackouts.
