Core Challenges in Deploying Remote Substation Monitoring Solutions

Remote monitoring for substations enables utilities to track the condition and performance of critical assets

Several challenges arise in deploying monitoring systems, especially in diverse substation environments.

1. Communications & Networking Limitations
Substations, especially those in remote areas, face networking issues. Urban locations may have reliable high-speed connections like fibre optics, 5G/4G LTE, or Ethernet, but rural or remote sites often rely on limited options like satellite links or private radio networks. These variations require flexible communication solutions that adapt to each location’s constraints.

2. Resolution & Bandwidth Constraints
High-resolution video and thermal imaging demand significant bandwidth, which isn’t always available. Utilities can overcome this by using sensors with local data processing capabilities, sending only critical alerts or lower-resolution images. This approach reduces the network load while allowing essential data to reach operations teams for timely responses.

3. Power Availability
While urban substations typically access the main power grid, remote sites may lack consistent power. Low-power, energy-efficient sensors are necessary in these cases, often powered by solar panels, backup batteries, or small generators. Power-over-Ethernet solutions also simplify installation in grid-connected areas, reducing infrastructure requirements.

4. Environmental Challenges
Substations face harsh environmental conditions, from electromagnetic interference to severe weather and wildlife hazards. Sensors designed for commercial use may not withstand these elements, so utility-grade equipment is recommended for durability and resilience, ensuring continuous operation under extreme conditions.

5. Sensor Placement
Optimal sensor placement is essential to capture relevant data. By using 3D models and simulation tools, utilities can determine ideal locations for sensors, minimising the number of devices required while maximising data coverage. Proper placement reduces installation costs and ensures that critical assets are effectively monitored.

Deploying remote monitoring solutions requires custom approaches tailored to each substation’s specific needs. Working with experienced vendors can help utilities select the right technologies and configurations to address these challenges effectively.
