Provided you had a reliable test set, testing RCDs used to be straightforward, but life is now getting somewhat more complicated. Peter Wade of Megger looks at why this is and discusses what you need ...

No matter what type of RCD you’re using, if you’re using it to do the job of a Type AC device, you should test it as if it were a Type AC device. In other words, test the RCD for the purpose for which ...

Considering the diode reverse recovery, an accurate design method of RCD circuit in flyback converter is proposed. The proposed method can achieve smaller clamp voltage errors and less power ...
