Description

Current transducers (rogowski coils) are toroidal coils without ferromagnetic core and thus they count as air coil. These coils are used to measure alternating currents touchless. The concept is based on the voltage that is induced by alternating current in air coils. To measure currents in a conductor, the coil is placed around the current-carrying conductor. The current flowing in this conductor generates a magnetic field, which induces a voltage in the rogowski coil / transducer. The height of the induced voltage is used as measured variable for the conductor current.

Advantages

- sturdy construction
- no damage of the transmitter due to current peaks
- not linear influence of the iron core nonexistent
- current measurement without opening the circuit
- big current measurement range (several kA)
- big frequency range (1 Hz - 1 MHz-area)
