Question no.1 (ask on 17/07/2014) : What is the operating principle of the AmpFlex and MiniFlex sensors?
answered on 17/07/2014 :
The Ampflex sensor is a transformer designed according to the Rogowski-coil principle. The conducting carrying the alternating current to be measured forms the primary circuit, while the secondary is formed by a special winding on a flexible support. At it terminals, this winding develops a voltage proportional to the derivative of the primary current to be measured. This voltage is then carried by a shielded cable to the casing containing all the processing electronics and the battery power supply.
