ROGOWSKI COIL SENSOR: https://www.lem.com/en/rogowski-coil

What is a Rogowski Coil?
Rogowski Coil sensors are Rogowski based sensors and used for measuring alternating current (AC) or high-speed current. The induced voltage being proportional to the derivative current in the straight conductor, it is common to plug an integrator to the output of the smart grid sensor as it will provide an output signal that is proportional to the current.
LEM is providing a complete range of Rogowski sensors (for both indoor and outdoor) and integrators.
5 advantages of LEM Rogowski Current Sensor
Rogowski sensors’ absence of magnetic circuit offer several advantages:
• Reduced cost
• Coil can be opened and is flexible, it can be wrapped easily around a live conductor.
• No saturation, resulting in high linearity.
• Low inductance, allowing for fast responses to changing currents.
• No inserted losses
On which applications can Rogowski coils make a difference?
Rogowski current sensors are suitable for various applications, from outdoor or harsh environment for utilities to indoor and C&I environments.
In these areas, they are especially designed for:
• Current monitoring for all typical applications (current demand, Energy efficiency, monitoring for grid or Industrial & commercial applications …)
• Demand power flow monitoring
• Fault detection
• Theft detection

Pls don’t hesitate to contact us if have any opportunity to explore. Thanks. 😊
