Gujarat State Electricity Corporation Limited (GSECL), is a leading power generation company in India that owns 10 power generation plants in the state. The switchyard at one of their power plants was facing issues due to inefficient operation of the disconnectors that were reaching the end of their life. This also meant a safety hazard for the personnel working on related operations at the power plant.
Hitachi Energy offered an easy-to-install disconnector retrofit service solution using existing on-site components. The solution was implemented within just three days without additional infrastructure investments. A standard installation like this would normally require plant shutdown of up to 15 days and civil construction. The solution is robust, with in-built safety features and is expected to deliver superior on-site performance.
“We are extremely pleased with the retrofit service solution that Hitachi Energy provided,” said the representative from GSECL. “The operations are trouble-free and efficient and avoid costly infrastructure investments. GSECL would like to replicate similar retrofit service solution for the other power plants in the Gujarat state.”
