Previously, to repair and overcome the existing problems on the grid, the working unit had to cut off all electricity and take safety measures before proceeding with the construction, interrupting the power supply, affecting electricity customers. The work often had to be arranged to be done at night, during off-peak hours, which was very hard and difficult for the workers.
But now, the application of science and technology to put into use the method of connecting and repairing equipment on the grid that is carrying electricity using Hotline technology has brought many benefits in the management and operation of the grid system.
With this job, after the Power Company checks and discovers any problems or defects on the power grid that could threaten an incident, it will be reported to the company. From there, the hotline repair team will coordinate to handle, replace and fix the problem immediately without having to wait or arrange a power outage plan like before.
Handling of incident threat at Nam Dinh Power Plant (heat emission above 100°C).
The hot electricity repair construction is applied by Nam Dinh Electricity Company with new and modern technology.
There are two methods applied: the method of using insulating rubber gloves and specialized insulated bucket trucks; or for inconvenient traffic locations, where bucket trucks cannot reach, the method of using insulating rubber gloves combined with insulated supports, insulated poles, or also known in the industry as the Platform method, is applied.
Implement the customer's new branch connection Platform method.
In addition to the construction work of repairing and replacing poor quality equipment on the grid, handling points at risk of incidents, the hotline construction work is also carried out in connecting and putting investment projects into operation quickly and promptly after being accepted as eligible for energization, helping to prevent overload, reduce losses, improve power quality, and serve customers better and better.
Connecting substations to prevent overload to ensure power supply during the hot season of 2023.
Hotline electrical repair is a new step forward for the electrical industry in the process of improving service quality as well as electrical quality.
Since applying hotline repair technology, Nam Dinh Power Company has always performed well the Hotline work on the grid, especially the regular repair work to prevent and fix defects on the grid promptly and quickly, contributing to reducing incidents occurring on the grid.
The application of hotline repair technology has brought many practical benefits and efficiency, helping to save time, prevent and minimize incidents on the power grid, reduce power loss, contribute to increasing labor productivity, improve the reliability of power supply, and meet the increasing demand for electricity of customers.
