Smart grid sensors continuously monitor key electrical parameters such as:

• Voltage levels
• Current flow
• Frequency stability
• Power quality
• Faults and outages

They send this data to utilities or control systems, enabling real-time decision-making and automation.

⚙️ Types of Smart Grid Sensors

1️⃣ Phasor Measurement Units (PMUs)

• Measure voltage and current in real time with high precision
• Use GPS timing for synchronization across the grid
• Essential for monitoring grid stability

👉 Used in wide-area monitoring systems (WAMS)

2️⃣ Fault Detection Sensors

• Detect issues like:
  • Short circuits
  • Line breaks
  • Equipment failures
• Help utilities locate faults quickly and reduce outage time

3️⃣ Smart Meters (End-User Sensors)

• Installed in homes/businesses
• Track electricity consumption and send data to utilities
• Enable dynamic pricing and demand response

4️⃣ Transformer Monitoring Sensors

• Monitor:
  • Temperature
  • Load
  • Oil condition
• Help prevent failures and extend equipment life

5️⃣ Line Sensors (Overhead/Underground)

• Installed directly on power lines
• Measure current, voltage, and environmental conditions
• Useful for real-time grid visibility
