Typical Energy & Power Applications

1. Substation Asset Health Monitoring

• Challenge: Legacy substations lack monitoring on critical SF6 breakers and transformers.

• Solution: Retrofit with NB-IoT SF6 density monitors and oil level sensors. Data is transmitted directly to the central control room, enabling condition-based maintenance and reducing outage risk.

2. Smart Distribution Grid (Pole & Transformer Monitoring)

• Challenge: Thousands of distribution transformers across a wide area are unmonitored.

• Solution: Install NB-IoT clamp-on current sensors on transformer low-voltage bushings. Real-time load data helps balance phases, prevent overloads, and optimize grid planning.

3. Renewable Energy Asset Management (Solar/Wind)

• Challenge: Remote solar farms and wind turbines require frequent site visits for basic checks.

• Solution: Deploy NB-IoT weather stations (temperature, irradiance) and vibration sensors on turbine gearboxes. Centralized data collection reduces O&M costs and maximizes energy yield.

4. Underground Cable & Manhole Monitoring

• Challenge: Underground cable vaults and manholes are prone to flooding, gas accumulation, and overheating, posing safety risks.

• Solution: NB-IoT water level, gas (H2S/CH4), and temperature sensors provide continuous monitoring, ensuring worker safety and cable integrity.

5. Environmental Compliance Monitoring

• Challenge: Need to monitor for oil spills from transformers near waterways or protected areas.

• Solution: Install NB-IoT oil-on-water detection sensors in containment pits. Instant alerts enable rapid response, preventing environmental fines and reputational damage.
