Example 3:
The wire to be monitored is "wound" several times through the
Bender current transformer in order to amplify the signal
Setting:
Factor: /3
Measuring current transformer monitoring: On
2. Response value
The response value is the value at which an alarm is output. In case of digital
inputs, set the status (0 or 1) at which an alarm is to be signalled.
Tolerances have to be taken into account (measuring current
transformers, RCMS…) whenever measurements are carried
out. The IEC 62020 specifies that the set response value shall
not be exceeded, therefore an RCMS… shall respond when
50…100 % of the set response value are reached.
Prewarning is therefore to be signalled earlier (x % of
50…100 % of the response value).
The current measuring channels k9…k12 of version
RCMS…-D4/-L4 have positive tolerances as regards the
response values.
