Application of plastic optical fiber in 10kV ring main unit

Application of Plastic Optical Fiber in Power Systems: 10kV Ring Main Unit Partial Discharge Monitoring Solution In modern power systems, the safe and stable operation of power distribution equipment is crucial. With the continuous improvement of power grid automation and intelligence, higher demands are placed on the real-time monitoring of equipment operating status. In 10kV power distribution systems, the ring main unit (RNB) is one of the important power distribution devices, widely used in urban power grids, industrial parks, and new energy power plants. If insulation degradation or partial discharge (PD) occurs inside the equipment and is not detected and addressed in a timely manner, it may lead to equipment failure or even power outages.

Why are plastic optical fibers being used more and more in power systems?

The operating environment of power equipment typically has the following characteristics: strong electromagnetic interference, high voltage environment, complex industrial environment, and long-term continuous operation. Traditional copper cables are easily interfered with in strong electromagnetic environments, while plastic optical fibers have natural electrical insulation properties and are not affected by electromagnetic interference, making them very suitable for use in power automation systems. The main advantages of plastic optical fibers in the power industry include: ✔ Strong resistance to electromagnetic interference

✔ Good electrical insulation performance and high safety

✔ Stable transmission and low bit error rate

✔ Flexible installation and low maintenance costs. Therefore, POF optical fiber is gradually becoming one of the important technologies for internal communication in power equipment.
