Bimetalic Ammeter With Maximal Current Indicator
Bimetallic and combined ammeters are especially intended for thermal monitoring of transformers, cables and other electrical devices which have a slow reaction to current changes. They indicate the mean rms current value during the measuring period of the meter (8 or 15 min.). These meters do not react to short current pulses essentially. The range of these meters can be enlarged by means of external measuring current transformers which are also offered
by LUMEL and can be delivered on request if the meter is ordered in the option enabling a direct assembling on the current transformer.
They enable:
– Thermal monitoring of electrical installation with a slow
reaction of current changes (transformer, cables, etc. …).
– Instantaneous reading of rms current values.
– Simple exchange od dials without internal interference.
– Direct plug in on measuring transformers.
