strømmåling
Strømmåling, or current measurement, is the process of determining the flow of electric charge in a conductor or circuit. It is fundamental in electrical engineering for monitoring power consumption, protecting equipment, controlling systems, and validating measurements in laboratories and industry.
In most cases, current is measured by inserting a sensor in series with the circuit so the
Common sensing technologies include shunt resistors, which produce a voltage drop; Hall effect sensors, which detect
Applications span electrical meters, switchboards, motor drives, battery management systems, power monitoring, and laboratory test benches.
Standards and calibration practices emphasize traceability to international units and repeatability of results. Measurement devices are
Limitations include potential circuit disturbance, temperature drift, and susceptibility to magnetic interference. Proper selection of sensor
