The cost to install and terminate fiber is comparable to that of copper wire. The lightweight, ruggedness, and flexibility of fiber allows it to be easily installed in the substation. Fiber optic communications are inherently immune to electromagnetic interference and provide electrical isolation between the connected devices, which drastically reduces the risks to personnel and equipment. Hardwired communication links are susceptible to electrical noise and distance limitations (up to 150 meters). With the introduction of microprocessor-based devices for monitoring, control, and protection, there is the need for high-speed, low-latency communications in the substation to exchange large amounts of critical data. The products used in these applications must be able to withstand the harsh substation environment, including extreme temperatures, high levels of electromagnetic interference, power fluctuations, and in some cases, vibration. These assets are monitored, controlled and protected by a complex collection of devices to ensure safe and efficient operation of the grid. Substations contain critical assets for transforming, switching and distributing power across the grid. AKM 44611/48471 Top-Mounted Thermometer.
