1 / 5
HF is a High Frequency Rogowski coil integrator, housed in a compact shield aluminium alloy enclosure and powered directly from the mains. It provides measurement for all kinds of waveforms such as 1/5μs, 8/20μs, and 10/350μs. With a frequency range from 100kHz to 1MHz, it features a direct connection to an oscilloscope.
| Core Advantages | Typical Applications |
|---|---|
|
• High read accuracy: 2% typical • Wide power supply: 4-12VDC • Multiple waveform restoration (1/5μs, 8/20μs, 10/350μs) • Measurement up to 500kA lightning current |
• Measuring devices and lab instrumentation • Lightning protection and monitoring • Pulse waveform analysis • High frequency current measurement |
Rogowski coils are used for the detection and measurement of electric currents based on a simple principle: an "air-cored" coil is placed around the conductor, and the magnetic field induces a voltage proportional to the rate of change of current. This voltage is integrated to produce an output proportional to the current.

Caution! Risk of Danger: Ignoring warnings can lead to serious injury or damage. Installation must be performed by qualified personnel. Ensure all national regulations are observed.
Caution! Risk of Electrical Shock: Parts of the module may carry hazardous live voltage. Ensure protection measures are in place. Disconnect power supply before maintenance.
Warning: Do not stress the coil with mechanical force (twisting, puncturing, excessive pressure), as this will degrade measurement accuracy.
