Residual current

The residual current flowing through the measuring current transformer 
is continually measured and displayed.

 

If the residual current exceeds 100 mA, it will be indicated on the dis-
play. 

 

If the residual current exceeds 2 A, an alarm message will be signalled. 
Once the residual current reaches values of this magnitude, reliable 
insulation fault location becomes impossible. 

ALARM            1/1

Residual current

   > 2 A
Addr.: 2 Channel: 1
