Before you make a decision on whether KROM suits your needs we suggest that you have a look at some of the videos below.
All videos have manually written subtitles. They can be turned on by clicking the CC-button in the lower right corner of the each player.
In this video you will learn why knowledge of air-gap flux density is critical in synchronous generator diagnostics. Flux-density asymmetry is a clear indicator of either winding faults or rotor whirl, i.e. dynamic rotor eccentricity. Regardless of the root cause, the result is rotor and stator vibrations. Without a graph of the flux density, distinguishing between electromagnetic and mechanical causes becomes a guessing game, complicating vibration troubleshooting and resolution.
In this video you will learn how to detect dynamic eccentricity by measuring the magnetic flux in the air gap.
The KROM offer has been made even better but don’t take our word for it, see for yourself in this video.
I found this video that I want to share. In the end I mention flux measurements with KROM.
In this video you will learn how magnetic flux measurements can be analysed. An electrical circuit is used as an analogy.
In this video Mattias goes through what to remember when measuring magnetic flux in the air gap of a synchronous generator. The second half of the video describes how to perform a measurement with the KROM flux meter from Genmag. The material in this part is taken from our other videos.
A whirling rotor can be detected with magnetic flux measurements. The principle is explaned with an animation in the video below.

In April Mattias spoke about magnetic flux measurements at the conference Enlit Africa in Cape Town. There are English subtitles that you can turn on under CC.
With KROM you can analyse average flux density per pole. This is a good way to find a faulty field winding.
Here is a three minute instruction on how to set up the KROM hardware.
Analysing magnetic flux with KROM is easy. Here you can see how easy.
Before you analyse your data you have to make a measurement.
As an accessory there is a termination box for the Hall sensor cables. The KROM flux meter has been improved with new sockets for a standard sensor cable.
