Smart Grid Sensors

LEM sensors enable precise monitoring and optimization in a wide range of applications

Image of LEM Smart Grid SensorsLEM smart grid sensors are designed to deliver the precise monitoring and optimization required for smarter, more resilient energy systems. The electrical grid is transforming to meet new demands, from the rise of electric vehicles to the growth of renewable and distributed energy sources, as well as the increasing electrification of building cooling systems. Data centers and energy storage systems have become essential parts of today’s energy landscape. Managing these increasingly complex and decentralized networks requires smart infrastructure powered by accurate, real‑time data. LEM current sensors provide that insight, enabling precise monitoring and optimization of energy production, distribution, and consumption to enhance reliability, reduce waste, and support a more flexible, resilient grid.

Applications
  • Distribution automation: fault detection, isolation, and restoration
  • Grid monitoring (intelligent substations)
  • Protection and safety
  • Distribution transformer monitoring
  • Distribution automation: voltage control
  • Power quality
  • EV infrastructure
