BEIJING, Jan. 15(Xinhua) -- Invited by the Oman Electricity Transmission Company (OETC), six experts from the State Grid Jiangsu Electric Power Co., Ltd. left for Oman at the end of 2023 and carried out an eight-day technical support and exchange activity for their Omani peers.
Oman has a high proportion of power grid gas insulated switchgear (GIS) equipment, with 98 percent of the more than 100 substations in the country using indoor GIS and open-type transformer configurations. The aging of equipment and insufficient operation and maintenance has greatly affected the safe and reliable operation of the local power grid.
The experts from the State Grid Jiangsu first spent two days conducting comprehensive testing on GIS equipment at six substations in Oman. Through on-site investigations, they discovered that Omani power maintenance personnel detect radio frequency signals in the air, which were weak and led to significant deviations in the test results.
Therefore, the experts suggested collecting signals through built-in sensors to ensure the operational status of GIS equipment. Experts also introduced GIS partial discharge online monitoring devices independently developed by the State Grid Corporation of China, providing live demonstrations of their operation methods and receiving accolades from the staff of the OETC.
In the rest days of the trip, Chinese experts collaborated with Omani experts to jointly research operation and management solutions for GIS equipment suitable for the local conditions.
The staff of the OETC expressed that the equipment and management experience brought by Chinese experts have been very helpful, and they hope for further cooperation and exchange in the field of intelligent operation and maintenance.
