Which is the best current sensor for your power measuring application? Solid-core current sensing technology provides good performance at low cost. But split-core sensors are making strong progress ...

Rogowski coils (see Sidebar and References 1 and 2 at end) perform passive current measurement and are used in test and measurement devices and power-monitoring activities. Calibration is required to ...

Claiming to set new accuracy standards, the RT series ac-current sensors based on patent-pending, perfect-loop technology achieve an absolute accuracy of better than ...

One of the joys of writing for Hackaday comes in learning new things which even after a long engineering background haven’t yet come your way. So it is with the Rogowski coil, an AC current sensing ...

Swiss sensor maker LEM has developed a novel non-contact current measuring technique based on a differential adaptation of the Rogowski principle. Rogowski coils Invented in 1912, Rogowski coils are ...

The CTRC Rogowski coil current transformers are flexible, rope-like current sensors that can be connected around conductors. With their flexible design, the CTRC transformers are perfect for large bus ...

With switching frequencies of MHz and switching edges lasting less than 10 ns, GHz measurement bandwidths are required to visualise some of the important effects occurring in SiC and GaN converters.
