The Internet of Things (IoT) is revolutionising every sector — from agriculture to aerospace. But nowhere is its impact more profound than in electrical systems, both at the residential and industrial level. By enabling devices to communicate, collect data, and react in real-time, IoT is ushering in a new era of smart, efficient, and self-regulating electrical networks.
In this blog, we explore how IoT and smart technologies are transforming electrical systems, with practical applications, real-world benefits, and future trends to watch.

1. What Is the Internet of Things (IoT) in Electrical Systems?
At its core, IoT in electrical systems refers to the integration of smart sensors, communication modules, controllers, and cloud platforms that allow electrical devices and infrastructure to exchange data and make intelligent decisions.
This convergence enables:
Remote monitoring
Real-time data collection
Predictive maintenance
Energy optimisation
IoT-enabled electrical components
2. Key Components of IoT-Enabled Electrical Systems
Understanding the architecture of IoT in electrical environments involves several layers:
Vibration, current draw, and temperature sensors predict bearing or insulation failure.
Integrates with PLC/SCADA systems.
c. Energy Management Systems (EMS)
Centralised dashboards with real-time loads from multiple units or plants.
Track power factor, load shedding, and energy KPIs.
d. Power Quality Analysis
IoT devices detect harmonic distortions, flicker, sags, and swells.
Enables corrective actions.
e. Preventive Maintenance
Data-driven maintenance planning (e.g., transformer replaced before insulation breakdown).
Reduces unplanned downtime.
