strømsensor
Strömsensor, or current sensor, is a device used to measure electrical current in a conductor and convert it to a signal proportional to that current for monitoring, control, or protection. Current sensors are used in power electronics, energy management, and industrial automation to track load, detect faults, and enable closed-loop control.
The main technologies are shunt-based sensors, Hall-effect sensors, current transformers, and Rogowski coils. Shunt sensors place
Output and integration: Many sensors output a proportional voltage or current (for example 0-5 V, 0-10 V,
Applications and considerations: Strömsensorer are used in motor drives, battery management systems, renewable energy inverters, smart
