0..30 mA 0..30 mAI5 I6
The basic device with module is suitable for use
as a residual current monitoring device (RCM) for
monitoring alternating currents, pulsating direct
currents and direct currents.
With the monitoring of residual currents (RCM,
Residual Current Monitor) of an electrical system
via inputs I5 and I6 (terminals 29/30 and 31/32),
the basic device with module is able to trigger
warning pulses when the limit value is exceeded.
The system operator can be alerted before a
protective device is triggered.
The measurements in medium and high voltage
networks are made via current and voltage
transformers.
NOTE
· The residual current monitoring monitors
the residual currents via external current
transformers and, if a threshold value
is exceeded, can trigger a warning signal.
· Limit values and warnings for the device or
system operator can be configured easily in the
GridVis®software.
NOTE
The basic device with module is not an
independent protective device against electric
shock!
Type A
Type B and Type B+ (enhanced frequency
range)
Connection of suitable external residual current
transformers with a nominal current of 30 mA can
be made on residual current transformer inputs I5
(terminals 29/30) and I6 (terminals 31/32).
The basic device with module measures residual
currents according to IEC/TR 60755 (2008-01) of:
6.2 Activate cable break detection (failure
monitoring) RCM for I5 and I6.
The basic device with module has a “Cable
break detection” feature (failure monitoring).
With this feature, the basic device with module
monitors the connection to the residual current
transformers on the measuring inputs I5 and I6
(module mode Residual current - see chap. 9.2 on
page 34).
The cable break detection for I5 and I6:
· Can be activated via Modbus addresses or in
the GridVis®software.
· Is only available in the AC mode.
Modbus addresses for activating the cable break
detection (failure monitoring):
Modbus
addr.
Measuring
input Value/function
20051 I5 0 = Failure monitoring inactive
1 = Failure monitoring active
20052 I6
You can check whether the cable break detection
is activated in the user interface of your basic
device with module under Menu > Configuration >
Measurement > item Residual current.
If there is an interruption in the connection to
the current transformers, the following Modbus
addresses of the respective measuring inputs (I5
and I6) indicate the fault:
Modbus
addr.
Measuring
input Value/function
20418 I5 0 = Connection to residual
current transformer error free
1 = Error in the connection to
the residual current transformer
20618 I6
The GridVis®software also displays the
interruption in the connection.
NOTE
For further Modbus addresses, see the Modbus
address list for the device (download at
www.janitza.de).
