Purpose
Current intensity indicator DMA-3 is used to continuous measurement the value of the current in a circuits of three-phases.
Functioning
* Measuring the effective value of current in electrical circuit.
* Measuring the circumference of the circuit is separated from the power indicator.
* Index marked TrueRMS fitted with a transducer gives the correct value of the effective value of current intensity at deformed runs.
