Description
Moving iron panel instruments are predominantly used in the usual technical
frequency range 15...100 Hz for alternating current and alternating voltage
measurements in the ordinary technical frequency range 15...100 Hz.
Moving iron instruments practically show independently of the wave form -
also at high harmonic content - the effective value of the alternating current.
In order to avoid overloads when starting the engines aminstruments are ge-
nerally delivered with overload scales 2xIn /=100 % overload). The final
scale values correspond in .../5A and in .../ 1A to those of the current trans-
formers.
The scale course of moving iron instruments is in the beginning a bit com-
pact and almost linear between 10 and 100 % of the final scale value. The
length of the overload scale amounts to about 10 % for a scale of 100 %
overload referred to the scale length
