AHM1-RC analyzer

New network anlalyzer AHM1-RC

 

The AHM1-RC network analyzer has all the features of the AHM1 analyzer with the advantage of being adapted to use with Rogowski coils. This fact makes it the most easily installed analyzer of our range, together with all the benefits that Rogowski coils offer.

“One of the major benefits of Rogowski coil analysers is how easy they are to add to an existing installation. In addition to this there are numerous other benefits including their resistance to electromagnetic interference or their nanosecond reaction to fast changing currents.”

 What is a Rogowski Coil? 

A Rogowski coil, is an electrical device for measuring alternating current (AC) or high-speed current pulses.

It consists of a helical coil of wire with the lead from one end returning through the centre of the coil to the other end, so that both terminals are at the same end of the coil. The whole assembly is then wrapped around the straight conductor whose current is to be measured. There is no metal (iron) core. The winding density, the diameter of the coil and the rigidity of the winding are critical for preserving immunity to external fields and low sensitivity to the positioning of the measured conductor.

Advantages

  • It is not a closed loop, because the second terminal is passed back through the center of the toroid core and connected along the first terminal. This allows the coil to be open-ended and flexible, allowing it to be wrapped around a live conductor without disturbing it.
  • Due to its low inductance, it can respond to fast-changing currents, down to several nanoseconds.
  • Because it has no iron core to saturate, it is highly linear even when subjected to large currents, such as those used in electric power transmission, welding, or pulsed power applications. This linearity also enables a high-current Rogowski coil to be calibrated using much smaller reference currents.
