Recovery experience of power equipment from tsunami disaster

In 2011, Japan suffered from a massive earthquake and tsunami. Thermal power plants operated by the Tohoku Electric Power Company were also affected by seawater inundation. Almost all power equipment such as switchgears, motors, cables, wires in Shin-Sendai Thermal Power Plant were inundated. This study investigates seawater intrusion in several low voltage wires, and discusses the refurbishing criteria required to realize rapid restoration of the plant. Nearly 2600 wires were subsequently reused, and recovery was completed within five months. The plant resumed its commercial operation at the end of 2011, and wires have been working well until now.
