Background

A transformer substation plays a vital role in converting electric power between bulk and local distribution systems. With the growing adoption of unmanned transformer substations in modern power systems, ensuring their reliable and stable operation has become increasingly important. Continuous monitoring and proactive management are essential to track key parameters such as the operational status of the main control room, transformers, circuit breakers, isolating switches, as well as fire alarms and video surveillance in real time.

Given that many unmanned transformer substations are located in remote or dispersed areas, traditional wired monitoring systems are impractical. Deploying a WLINK 4G/3G router at each access point offers an ideal solution by providing a stable, reliable, and real-time cellular network connection between the substation and the central monitoring center—eliminating the need for fiber or fixed-line connections.
