110kV Transformer Station Maintenance Service
Due to the increasing electricity demand, transformer stations are appearing more and more. With the function of increasing voltage to reduce power losses during the transmission of electricity to the point of consumption, this is an indispensable component in the power system.
Among them, the 110 kV transformer station is a transformer station with an installed capacity of 2x 25 MVA, responsible for supplying electricity to an area, it can even supply electricity to an entire district.
During operation, the 110 kV station needs to be periodically maintained to avoid damage, ensure stability, and increase the life of the equipment.
The necessary of 110 kV station maintenance
Because the transformer station operates regularly and continuously, it can be overloaded, leading to damage.
During operation, the 110 kV station needs to be periodically maintained to ensure stability and increase the life of the equipment. This maintenance is carried out periodically according to the published regulations of the product when installed.
Over time, some equipment in the 110kV station may encounter some problems that cause damage. The most obvious signs are broken fuse wires, and power outages in the entire system. The cause of the problem may be due to internal equipment errors or incorrect power usage, or it may be due to natural disasters such as lightning, fire, or animal damage.
Carrying out maintenance of the 110kV transformer station will help minimize damage or serious electrical problems that may occur because the technician will have to check the entire transformer station to see if there are any problems. This helps prevent and limit the dangers caused by the station to people as well as other electrical equipment.
