Current Probes at ILEA

We develop current probes with three different measurement ranges.

Isolated current sensing is one of the many research focuses of the institute of power electronics and electrical drives. The developed current probes can measure both static and dynamic currents very precisely.  

Three devices are developed for the measurement ranges of 200 A, 800 A and 3000 A, which can measure random current flow of direct and alternating currents.

Detailed information can be obtained from the datasheets shown below.

Challenges of current measurement in power electronic circuits:

  • Power flow is realised by the pulsed operation of the semiconductor devices

  • High switching frequency reduces the size of the energy storage devices

  • Fast switching operations reduce the switching energy losses
