Application
Combined bimetallic instruments are intended especially for thermal monitoring of transformers, cables, etc. due to their slow reaction to current changes. They indicate mean r.m.s. current value during the measuring period of the instrument. The instrument does not react to short current pulses essentially. Maximum mean value in a response time period is indicated by the red slave pointer. The latter can be reset or set to zero by means of a knob which can be sealed. Besides the bimetal system the instrument also includes a moving-iron system which measures instantaneous r.m.s. values.
